Hello Dear Prospective Customer.

You should know that we don't build games we don't play games either. :-)

We are dedicated to keeping costs low for our customers. This means 1.) the cost of creating the app and 2.) the ongoing cost of maintaining/improving the app. That is why we use a single code base architecture, to the greatest extent possible. ("single code base" means that there is one set of code for all three mobile platforms - iPhone, Android, and Windows - so that one code edit can change the functionality in all three platforms.)

Hybrid apps and Xamarin apps:

There are two approaches that achieve single code base architecture - hybrid apps and Xamarin coded apps. We use either approach, as appropriate.

The speed and responsiveness of these apps continues to improve and the cost savings in app creation and app maintenance is jaw dropping.

Additionally today's coding frameworks which we use to build these apps, enable us to work very efficiently and pass the savings on to you.

In conclusion:

Whether you have a great consumer app you want built, or an enterprise app for improving efficiencies in-house, we are at your disposal to help you realize your vision.

I'm an independent businessman in Pittsburgh, Pennsylvania and I am ready to work hard and get your app built with all the bells and whistles. I use a super flexible staffing model and pull in resources as needed to get your app delivered on time.


  • apps are tested on iOS, Android, and Windows hardware as needed, so we have no doubts it will run on your hardware.
  • and I can set up the server with any needed database and/or web services

This app accesses the phone's SMS system to text your business card, or whatever 4 lines of text you want. In Google Play and in iTunes
The data is in the cloud so if Mom has an iPhone and Dad has an Android, and they use the same account, they share the same data. Powerful Home and Store views.

I've been a developer and a business owner for ... a long time and have seen alot of trends come and go. I have a distinct knack for picking winners. - code techniques and technologies that improve efficiencies and performance.

Because I am a coder, I can make sure that coders working for me are efficient and working hard - also helping them out if they get stuck.

I want you to know that if you have pdschullerDotCom LLC make your app, you are in good hands.

Thank You
Phil Schuller
