My Apps

Over the years, I have built some pretty awesome apps. Some personal projects, some work projects, and many open source. Check them out:

My Cadence

Big, simple, cadence (RPM) display for indoor cycling. Connect a cadence sensor & in seconds you are ready for your spin & fitness classes! Free with no time restrictions!

My Stream Timer

My Stream Timer is an easy to use countdown and count-up timer for streamers. Multiple timers are available that write a file to disk to use with OBS, SLOBS, or your favorite streaming application. Have it auto start so it works with Stream Deck! Built with WPF and .NET Core 3 and completely open source on GitHub. Available on the Microsoft Store for Windows 10 and macOS.


Meissner Nordic

Meissner sno-park grooming & weather reports, announcements, events, trail maps, and more. Everything you need for a fantastic cross-country ski trip. Take the trail maps on the go with offline access to every map in the sno-park.

Retired Apps:

At some point apps have to be put to rest, and a few of mine have been.


Leave that pen and paper behind: Scoreboard enables you to easily keep score for any game with up 4 players or teams. Effortlessly keep track of game scores including board, sport, dice, or anything else!

Scoreboard doesn't stop there, as it also keeps a full history of every game that you have ever played along with scores, so you can go back and check the scores later.

Scoreboard works great with all sorts of board games such as Qwirkle, Sushi Go, Dominoes, Phase 10, and Mastermind. It is also great for dice and sports such as baseball.

Meetup Manager for Organizers

As a Meetup.com organizer, I always wanted a way to check in attendees, and that is where Meetup Manager came from! It is available for Android, iOS, Windows Phone.

My StepCounter

One of my favorite apps that I built in my spare time is My StepCounter. I built it around the time that Android Kit Kat came out, and this was the first time Android had a built-in pedometer API. I built My StepCounter for Android, inspired by Mike James' original project for iOS. You can grab it on Google Play today.

Social Post

Frustrated that Apple removed the ability to easily tweet without having to open the Twitter app, I built Social Post, which allows you to easily post to Twitter and Facebook without loading up their full apps. You can grab it on the App Store.

My Media Center

The first professional application that I developed when I worked at Ceton was My Media Center. This app gives you full control of your Windows Media Center PC. I developed the app for Android, iOS, Windows Phone, and Windows Store.

Puppy Kitty Overflow

A super silly and fun app that I built in a single day, Puppy Kitty OverFlow plays animated GIFs of cute dogs and cats. Available on Android, iOS, and Windows Phone, and of course open source on GitHub.

Days Until Xmas

ChrisNTR built the perfect iOS and Windows app to count down the days until Christmas, and I decided to bring it to Android! You can grab the source code on GitHub and download it from Google Play today.

Xamarin Evolve (2016)

After building the 2014 Evolve app, I was in full control once again to build and innovate for the 2016 app. With full online/offline synchronization, labs, calendar integration, push notifications, and so much more, it is one of the coolest and largest apps that I have published. You can read more about it on the Xamarin Blog and find links to the source code!

Bike Now for Pronto

When Pronto bike sharing launched in Seattle, I knew I had to build an app, and Bike Now was born! Inspired by Jeremie Laval's Moyeu, you can browse for stations and see how many bikes are in each. Available open source on GitHub and downloadable on Google Play.

The Digital Media Zone

The first app that I ever wrote was The Digital Media Zone, and it was for Windows Phone. You could browse news articles, save them offline, and even stream the DMZs podcast right on your phone.

Xamarin Evolve 2014

When I started at Xamarin, I had the privilege of working on the conference app that all attendees would use. It was built with Xamarin.Forms version 1.2, and it was pretty great. You can read about it on the Xamarin Blog.

Evolve Quest
