Semaphore APPlying Expertise; IoT

The Internet of Things (IoT) allows for the constant advancement of that which is good – and making it better. As mobile app developers for more than a decade, long before an “app” was called an “app” – Dallas’ Semaphore Mobile was building “productivity tools,” so too has the team been creating IoT products long before there was such a moniker.

“IoT is all about access to information and the opportunities are limitless from phones or any other internet access,” said Semaphore’s Founder and President, Eric Silverthorn, whose company has developed nearly 400 iPhone apps and close to 300 for Android. “We’ve been building the technology since it was simply called ‘engineering,’ – now, it’s IoT. Whatever you want to call it, it can make any industry, any company, any user, stronger.”

The industry isn’t mellowing any time soon, more products, more tools, and more options available and always on the horizon. With the population using their phones, for much more than talking – lots more than they are talking the opportunities for apps to be received, used, and relied upon grows literally every second – of every day – for every product.

Semaphore has developed apps for iPhone and Android devices in numerous fields, from a lighting company who can control the illumination in their stores or on billboards to a utility company to determining how much, and how, its customers are using electricity. A softdrink company is determining its inventory in any given machine, how much money is being held, and what needs replacing.

“We have a definite understanding both the hardware and software needs of our customers and of how I0T can be implemented to meet their needs,” said Silverthorn, “Our expertise enables our customers to cost effectively use the technology – and the technology to support our customers’ best.”

Semaphore Mobile APPlying 10 Years of Expertise to Support Startups!


Dallas’ Startup community is celebrating itself this week as Dallas Startup Week 2018 begins.  For five days from early morn til the wee hours strike, founders and funders, hopefuls and hiring types will make their way from Uptown through Downtown and far up to Frisco with events dotted along the way.

Semaphore Mobile not at all a startup – the company celebrating 10 years and nearly 400 iPhone and close to 300 Android apps developed is proud to be a part of DSW ’18 and all connected!

From the time that Semaphore’s previously produced for private sector clients “productivity tools” became known as apps – with the launch of the Google Store and AppStore providing a market for the greater public to enjoy –  Semaphore’s founder and president Eric Silverthorn has remained present in all areas of the market.

Semaphore Mobile’s locally based team, with admin and project development management and developers local, is of great benefit.  “About 20 percent of our customers have come to us as a second resource, their first ‘across the pond,’” said Silverthorn.  “It very rarely is cheaper, faster, or better when outsourcing development projects and we’re proud to have our team here in the Dallas area, available when our clients need to reach us.”

Starting up is something Silverthorn knows much about – his career starting as a radio engineer then morphing into a satellite systems designer.  Traveling the globe, 100+ countries in a few short years, Silverthorn was a pioneer in that industry as well.

Still, connecting to Dallas’ Startup community has been about learning, teaching, and growing.  Meeting new faces, and learning about new product and resource, has made for new clientele – referrals – and relationships.  “Being out there and getting to know who are the up-and-comers, and seeing who we can help succeed is what it’s all about,” said Silverthorn.  “As an entrepreneur, you are always starting, growing, and building.  The day you think you are above those coming in – you’ll be on your way out.”

Taking the capabilities he once offered to clients around the world to be in touch with their teams, Silverthorn, who is a Houston native who has made North Texas his home since 1990, and Semaphore Mobile have made startups its sendup.

“We’ve worked with companies large and small and there’s almost no area we haven’t addressed,” said Silverthorn, noting that games are the only format not in his wheelhouse.  “From health to shopping, food plans to plumbing inventory and music programming – we’ve done it all and we’re always looking or the next great challenge.”

You APPsolutely Need to Revisit, Revise, and Research


Since 2008 millions have found an “App for that,” and millions more have tried.  Eric Silverthorn and Semaphore Mobile stepped into the arena at the start, one of Dallas’ mobile app development forerunners, creating productivity tools before the word “app” came to be.

In 2002, a Liberia-based client requested the ability for security and productivity tools.  With Blackberry and Nokia at the helm of the market, Semaphore created a format that focused on the provision of mobile application software solutions to enterprise customers.  The allowance expanded to include the prototyping and development of industrial control systems that interconnect to mobile networks, and Semaphore’s products allowed users to transmit and receive data in remote environments – services which continue today through the Dallas mobile app home-base.

With the 2008 announcement that Apple would be hosting software applications used on iPhone and iTouch devices, it was a natural transition for Semaphore Mobile to enter the mobile app development arena and the last eight years have seen Semaphore’s production of nearly 400 iPhone Apps, including more than 100 for iPad, and close to 300 for Android operating systems.  There were 500 apps available on the App Store in its premiere summer, today that number is over 1.5 million, and for Android users there are another million.  That’s a lot of competition, and the Dallas mobile development field has grown – with many companies that come – and go – in a blink.  The Semaphore Mobile App development team has survived, and grown stronger.

“The world changed with the opening of the App Store and what we’d built as internal communications tools quickly became a format opening to the public market as well,” said Silverthorn, Semaphore’s founder and President.  “One of our first public Apps was a Craigslist App and in a quick flash, the opportunity to build entertainment, health-related, and countless other subjects came about.  We stepped in and the mobile application development opportunities are now seemingly endless.”

As the startup and entrepreneurial market has grown, Dallas’ mobile app development needs have expanded significantly.  Co-working spaces, filled with companies on their way up – provide a bevy of prospect.

Semaphore’s capabilities include mobile application development to support entertainment, health care, browser, e-commerce, mobile network monitoring tools, points of interest GPS/triangulation location, GSM remote command and control of industrial equipment, security software message encryption.

“We’ve been in the Dallas mobile app development market since before the market opened and I’m proud of the work we’ve done,” said Silverthorn.  “We have clients who’ve returned for enhancements and second and third new applications and it’s been a great experience.  The idea that there’s an ‘App for that’ is a great truism and at Semaphore, we haven’t been stumped yet.”

2017 disAPPearing: Mobile Dev & Cloud Services in Review

As we come to the end of another year we reflect on the changes and growth in our own lives; personally and professionally and – in doing so – stop to review how the world of technology is constantly enhanced, making improvements to every aspect of our workspace daily. The functionality of an app will determine if server development is required to support the app.

If we roll back 15 years, a lifetime in this development space, companies needing a server  had to buy a piece of hardware, find a place to host it, deal with the burden of maintenance and capital expenditures for an item that was constently depreciating.

With the introduction of cloud services and hosted solutions the need to physically own the hardware became unnecessary.  “Click here” on a website and reach server backend hosts such as Amazon AWS, Google Cloud, and Rackspace, and pull more services, or downsize if necessary, allowing customers to manage the backend themselves.

“All three of these companies, and there are others, who provide excellent service.  We all have a responsibility to perform an analysis to determine which server host best fits the requirements,” said Eric Silverthorn, president of Dallas-area based Semaphore Mobile which, since 2008, has produced nearly 400 iPhone apps and close to 300 for Android users.  “User login for instance requires a database that holds its client’s information. In some instances, such as apps that allow users to play videos, an app may need content management to support the backend system to hold the videos.”

There are third party companies, such as Twilio, that allow app owners to leverage the functionality such as user authentication or build of chat rooms.  These services, offered through API connections can save a significant amount of time and money when building an app.

 “Semaphore Mobile’s team of programmers, for IOS, Android, and Ruby on Rails, provide superior development services for our clients,” said Silverthorn.  “New year, new season, and for our Semaphore’s team in our tenth year in the market providing development, strong service and support, and good guidance.”

WrAPPing Up the Year With Updates, Upgrades, & New Products!

It’s the end of the year and people are fitting in their last minute medical checkups, dental appointments, and treatments to be sure they are healthy – ready for the New Year more wealthy and wise!  With many upgrades and new products on the market, and millions of products being purchased between Black Friday and after-Christmas sales, making sure the products you are providing to your clients – and moreso the products you want to provide to new customers are fresh, clean, and able to meet and beat the needs of the ever-growing mobile market.

“You can’t just build, release, and watch and wait – you have to test, and retest – to update and be ahead of the market,” said Eric Silverthorn, president of Dallas-area based Semaphore Mobile which has produced nearly 400 iPhone apps and close to 300 for Android users.  With its full team working in the DFW Metroplex, Semaphore Mobile creates from the start, and is able to update, and upgrade, its own products and those built by others.  “The millions of apps that are out there and being used are pulling from your product and you need to be sure than when a user comes to you, it’s working – and it’s sharp.”

With each new model of phone, tablet, and more, even the slightest of updates to an app brings the possibility for bugs to creep into the programs.  Testing, testing, and testing again is of course key, but even with the greatest of preparation, given the combinations of technology, it’s sometimes difficult to beat the bugs.

“Bugs are the beast and they’re out there but the more we test, the more we communicate with our clients, the better chance we have of being polished,” said Silverthorn, his team dedicated to working with their clients; regular testing, regular follow-up meetings, and support available once the product is released.   “Short of our customers each having a fulltime team – and that comes at a mighty overhead, allowing our team to be involved with your product and review on a regular schedule, will save time, frustration, and negative response from users.  It’s not always ‘easy’ to beat the bugs – but that’s what we do.  Moving apps ahead with operating systems upgrades is a must.”

It isn’t about reinventing the wheel, just making the wheels you have spin sleeker, perhaps be shinier, hold more tread, and most certainly perform – and out-perform – out on the road.

Semaphore Mobile joins the App and Google stores now in a decade in providing creative, responsive, and reliable products to the market – with many of its clients returning for their support and referring their service.

Check-in, and check up, your product with Semaphore Mobile’s team and ready yourself, and your users, with a fresh start, to a fresh year.

APPreciating Tech Connects to Goodness; Semaphore Mobile hAPPy to Connect Community

Our phones, tablets, and watches are with us 24/7 and with that the opportunities to do good – to be good are as well.  While education and entertainment-related apps, and those for travel, business, health, social connections and professional productivity tools are the vast majority of how we spend our time, it is the handheld reminders and prospects that allow users of all ages to connect to lending support.

In the blink of an eye, you can be linked to make a charitable donation or register and participate in fund-raising sport or other activities, to finding volunteer opportunities or daily diaries of carrying out random acts of kindness and spreading smiles.

“There really is an ‘app for that,’ and ‘that,’ includes giving and doing for others,” said Eric Silverthorn, president of Dallas-area based Semaphore Mobile which has produced nearly 400 iPhone apps and close to 300 for Android users.  With its full team working in the DFW Metroplex, Semaphore Mobile looks forward to projects that make a difference.  “We’ve done projects large and small, those that build business, others that build businesses closer to their communities. With almost 10 years in the market there’s little we haven’t been approached about and we are always up for the challenge.”

Humanity, and reaching out – there’s definitely an APPreciation for community members to APPly support to those in need.  As the holiday season is almost upon us, realize how you and your company can build a stronger sense of community within, or to the broader public, by action-based events and programming, donations, or other creative realms, or how you as an APP user can spread your heart, and smiles.

iPhone & Semaphore are Celebrating 10! Let Semaphore Mobile bring you and your clients up to date!

Semaphore Mobile and the Apple iPhone are turning 10 this year and a celebration of the future that is now is happening!

Your Momma may have taught you that looks aren’t everything – still true – but that you have a look is something and something big beginning this fall with Apple’s new iPhone X with Face ID and a 1,000,000 to 1 contrast ratio bringing every color to its truest value.   The enhanced cameras, wireless charging, a 5.8” screen that fills the body with little framing at all and no home button!  Apple is all in with cameras on the front and back making augmented reality absolute reality, animojies that bring your expressions and words to life.

Also new, and slightly less pricey, is the iPhone 8 and 8-plus – if anything Apple does can be considered “standard,” with better cameras and general upgrades to the 2016 models that include wireless charging, shiny glass backs, an A11 Bionic processor, two gigs of RAM, and they can shoot video in 4K.

“Watch” out for the newest wrist manager – Apple’s third edition, cellular version, allows the user to make calls while away from the phone and Apple TV 4K, with HDR and more are also on the way.  Sitting still – or surfing the seas – Apple goes ahead of the flow to make it possible for the user to stay ahead, taking one bite at a time.

Steve Jobs would be proud – he thought different, and wanted us all to do the same! Semaphore Mobile thinks different, we think ahead and ready, and we’re here to bring your new apps to the audience, and to update your already posted products to market too.

“We’re motivated and we’re excited at the introductions and our team is ready to design and create for the next generation of Apple greatness,” said Eric Silverthorn, president of Dallas-area based Semaphore Mobile.  “The business is absolutely different than when we both came on the scene but we’re strong and successful and thrilled to still be producing the best products for the market.”

Semaphore Mobile had 12 apps posted the day the APPle Store opened, and another almost 400 in the decade since – along with almost 300 Android apps. Semaphore Mobile, with its whole team and production in the DFW Metroplex, is ready to bring you to the newest future – the future which is here.

Welcome to double digits iPhone. Semaphore Mobile is honored to share a decade of excellence with you!

Testing the Top of its Class; APPdev Semaphore Mobile Studies Up!


Almost a decade into the technology of mobile applications – as the public clicks, swipes, and types, the stakes are high for the millions of apps posted to the market and patience for products that misfire, is rare.

While the products that apps are built for have changed over the years – evolving constantly with updates and new forums and formats posting by the minute – so too have the ways for developers to test for those products and the learning curve – is but quick!

“When the Appstore opened, everything was tested manually – an easy trial as Apple’s product format is one background,” said Eric Silverthorn, President of Dallas-area based Semaphore Mobile – the area’s longest standing development house.  “Testing for Android presents an issue regarding manual testing because with so many device types, so many manufacturers, the many users have Android operating systems that are several years old. Android – not a one-stop test all.”

“Automated testing can be helpful however scripts have to be written correctly because errors likely create situations where developers are chasing bugs that don’t truly exist,” said Silverthorn, whose Semaphore Mobile posted 12 products to the 2008 opening of the App Store, and followed with Google almost immediately.  “Developers testing have to answer the question of ‘are problems in the code I have deployed a part of the app, or is the issue related to the test platform we are using.’”

With a 100 percent of the Semaphore Mobile development team in Dallas, the group is able to be on task, and on the money, for its clients.  Testing is done in-house and then with the client, before sending products to market.

For Semaphore Mobile, in its tenth year of developing for Apple and Android operating systems – with close to 400 iPhone apps and nearly 300 for Android – their design, and testing capabilities, put them at the top of the class.

Don’t grAPPle with amateurs. Semaphore Mobile’s Experience matters!

How much will it cost? The first and most-oft asked question is “how much will my app cost.” There is no flat cost or flat rate – and the answer will always be it’s about the time spent on the project; the client’s time, the developers’ time, and the coming together  in the progression of the journey to close on publication.

Rates will also vary on the expertise and talents of the team you choose to develop your project – as in any industry there are those who will promise the world, but deliver the dungeon and others who are able to more realize your goals in practical form.

“There is no obvious path for any one of our clients but for almost 10 years we’ve been able to treat our clients well, to produce what they want, and to bring their products to market,” said Eric Silverthorn, President of Dallas-area based Semaphore Mobile – the area’s longest standing development house – which posted 12 products to the 2008 opening of the App Store and which has since created close to 400 iPhone and nearly 300 Android operating system apps.  “Many of our clients have returned for additional development enhancements, new products, and word of mouth has definitely been our best public relations model.”

Semaphore Mobile’s 100-percent locally based team, from the admin and project development manager to the lead developer and his team, are available to its customers.  Rather than hoping that you or your team on the other side of the world will be awake during working hours, you can be sure that this hometown, home team, will hit your timezone.

“About 20 percent of our customers have come to us as a second resource, their first ‘across the pond’ as they say,” said Silverthorn.  “It very rarely is cheaper, faster, or better when outsourcing development projects and we’re proud to have our team here in the Dallas area, available when our clients need to reach us.”

“There is no obvious and guaranteed path for app development and we have many clients who’ve come in looking for just one format – and decided to develop both,” said Silverthorn.  “We’ve had clients come in with a design drawn on a napkin – and others with incredibly mature plans – and we’re able to turn both versions of the dream into reality.”

Expertise? Semaphore Mobile’s development team has nearly 100 years worth of combined experience and the camaraderie and respect from all levels of the company is strong.

Using collaborative tools, the team stays connected to each other and its clients by using Join.Me, Basecamp, screenshare capabilities, frequent meetings and calls.  Again, that Semaphore Mobile is based in the central time zone, rarely are team members more than an hour or two off the clock of their clientele.

With communication truly the key to success, there can’t be enough opportunities to be sure the plan, and thereafter support, updates, and more are able to meet the clients’ needs.

“App”roaching a decade of success –

Semaphore Mobile’s team has been producing since before the Apple & Google stores launch!

“Sure we can make that happen!”

That was the beginning of Semaphore Mobile’s foray into the App world – actually the beginning of bringing what was, to what is – using format and forum of what Semaphore’s talent had been building productivity tools – really the first concept of applications, apps, for Blackberry, Nokia, and Palm, to the greater public as iPhone and Android expanded the space that commerce had been using for years.

“We got a call from a marketing company to help build the first Craigslist app and, because we were the team experienced in Objective C, we had a leg up on the requirements of the App Store before it opened,” said Eric Silverthorn, President of Dallas-area based Semaphore Mobile – the area’s longest standing development house – which posted 12 products to the 2008 opening of the App Store and which has since created close to 400 iPhone and nearly 300 Android operating system apps.  “Three weeks later it was up and running with the debut and in the next year we did nearly 15 projects in the healthcare, entertainment, food, review apps, and more.”

As brands embraced the concept of mobile, as a magical brand extension, marketing with Semaphore broadened the possibilities.

“We’ve gone from the intro of mobile apps for people’s phones – to their tablets and watches and the skies are almost limitless,” said Silverthorn.  “Formatting is what it’s all about and we’re able to build whatever the client’s focus is.  While phones and tablets can be coded universally, watches don’t need page builders and desktops and laptops don’t need GPS.”

The APPetite for apps continues to grow and Semaphore’s local development team continues to expand to meet the desire industries-wide.  “There’s a generation who has grown up APP-ful who can’t remember a time without being entertained or ordering up, at the stroke of a swipe,” said Silverthorn.  “We’re proud of the work we’ve done and excited about what’s to come.”

“Sure we can make that happen!,” – starting its tenth year, making it happen is still Semaphore’s answer, still Semaphore’s commitment.
