Felker Tech is a brand name created by Nick Felker, a web and Android developer, for personal and freelance projects


You'll get projects with the latest designs for mobile devices and PCs. Following native design trends mean things are faster, more reliable, and means users will give better reviews.

 Multi-Device World

It isn't enough just to target one device class. Responsive design allows apps and websites to scale from wearable computers to phones, tablets, PCs, and TV consoles.


As a developer, I can help you figure out what kind of project you're trying to build. Even if I'm not working on the project, I'll lend advice. I enjoy technology and am excited to build new things.

 Social Media

Marketing your project to others isn't always easy. I can help set up social media strategies, plus SEO (search engine optimization) will also improve your ranking on search engines and increase page views.


Here are some projects that I have developed.

Web Apps


This is an open source word processor that is designed to greatly simplify the writing process. Formatting is often a large barrier to writing, and that's the greatest problem that Gltn solves. The web app will format your document perfectly based on any sort of format. There's plenty of APIs in place to format papers, run plugins, show themes, and plenty of other really helpful tools. It's available on GitHub.

Android Apps

Weather Delta

The idea of this app was to use a simple interface to convey to the user the weather over the course of the day. Colors play a primary purpose in visualizing the change.

In addition to working on mobile, watches, and TVs, there is a watchface available as a premium feature. A widget is also included for users to keep the app on their homescreen all day.

Android Games

Gaming is a very popular industry that allows users to quickly get acquainted with a topic and master it. Simple user experiences encourages learning and productivity along with keeping a high user retention.


If you talk to a random child in Philadelphia, they probably couldn't tell you much about the city's local history. How could students learn? There is a mobile site like the History Channel, where they'll be pummeled with ads. Alternatively, other sites end up reading like a boring report. There is not a great way for young students to learn history outside of a lecture, classroom setting. nVader allows students learn history in an independent way through exploring a city and collecting items in areas of more historical significance.

Epic Table Tennis

Responsive games, games that can be played on any operating system, on any device, are uncommon. A lot of infrastructure needs to be developed under the hood to work with mouse, keyboard, touchscreens, gamepads, etc. While this is possible for AAA game companies,a lot of indie developers only create simple HTML games or Android games. It's hardly cross-platform or responsive. Many solutions require a lot of special work to compile, or are finanically prohibitive to new game developers. Plus, these custom libraries are often hacky and don't use best practices.

This game was built using the open source Web Game Bridge library, a library designed to give native features to web games. Though the game is written in Javascript without any additional effort, the library detects device types and applies features like native login and game services when on Android. Epic Table Tennis is developed to have the same experience on any device or platform while feeling like a native game.

Android Wear

Android Wear is a very powerful new platform. Wearable devices are designed to let technology fit seamlessly in our lives. It's always connected, and always available to you. There's no need to pull out your phone, unlock it, go to the app drawer, and open the app. How does that change our use of technology?

Additionally, there's another really powerful element here, and that is ubiquitous computing. Computing is, of course, all around us. However, computers don't always know that. If I have a tablet and a laptop, how well do they communicate? Android Wear comes with APIs to communicate between your devices, allowing for remote control as well as having a rich ecosystem that works together.


This is a collection of premium watchfaces that shows you data in addition to the time of day.

Wrist Dice

My first published app for Android Wear is a dice roller. This is a great use of the wearable platform. With a quick voice command, you're in the app. You can quickly roll a variety of dice. Dice appear as circles or squares. The mobile app can change settings on your wearable. Everything stays in sync, which reduces setup time.


This idea comes from my jazz band. How can one get a sense of a beat without a drummer? Blocky metronomes are loud and overpower the band. This is where wearable technology really shines. Being on your person, it can inform the conductor through an inconspicuous vibration. This app also employs remote control features. It's hard to scroll through beats per minute on a watch. So, I can enter a number on my phone and get that value mirrored on my watch. I can start and stop on either device. It's two devices, but a singular experience. It's a simple yet great example of ubiquitous computing.
