Cross-Platform In-App Purchases for Xamarin.Mac Apps!

This week, one of my best friends Frank Krueger released his brilliant app iCircuit 3D for macOS (he also wrote an awesome blog on how it was made). While I know that catalyst support for Xamarin (and .NET MAUI) is coming soon, I still think there are great opportunities to monetize macOS apps written in C# today (see iCircuit 3D!). I released my In-App Billing Plugin a few years ago for iOS, Android, and UWP apps and it has been awesome to hear how it has helped so many developers monetize thei…

Introducing My Cadence for Arduino, a DIY Cadence Display for Indoor Cycling

It is official, my holiday hacking is officially complete! This past week I started and ┬álaunched a brand new app called My Cadence for both iOS & Android. This simple cadence display app is a perfect pair for my recent $400 DIY spin bike that I have been using for Peloton and Apple Fitness+ classes. However, my holiday hacking wasn't complete until I brought My Cadence to a third and final platform... Arduino! What sparked my interest was when snowzach posted on HackerNews his Arduino proje…

Asking for app reviews really works! It just takes 1 line of code!

Last week I launched a new app called My Cadence for both iOS and Android. Even though it was a quick app that only took me a week or so to build and ship, I still followed my checklist of best practices to ensure as much success as I could. I of course did real world testing myself and with TestFlight users, I tested light and dark theme modes, and I even put in-app purchases in from the start! Even with all of this, there one line of code (using the Store Review Plugin) that can really make a…

Porting My Cadence to Android in 1 Day!

It seems like it was just yesterday that I was writing up a blog post on how I was launching My Cadence for iOS and then blogging about how I wrote and shipped the app in under a week. Well, it wasn't yesterday, but it was just 5 days ago! After I shipped the iOS version, I was watching some HGTV on Hulu and thought to myself, "how long would it take me to ship this app on Android?". The answer is around 4 hours' worth of work, and about 4 days of waiting for Google Play to approve my applicatio…

Building, testing, & shipping My Cadence for iOS in less than a week

My holiday hacking came early this year when I decided to build my own DIY spin bike. Soon, after a few rides, my mind started to swirl with app ideas of how to improve my ride. Then when Apple released Apple Fitness+ without support for displaying cadence information from sensors I knew I had to build an app. That app is My Cadence, which connects to a small cadence sensor and displays the current cadence. It is actually packed full of awesome features including custom themes, in-app purchases,…

Introducing My Cadence for iOS & Android - a Simple Cadence Sensor Display

It has been nearly 3 weeks since I put together my DIY spin bike and I have now clocked in over 25 rides! Let's just say I am really enjoying have the bike at home now that it is chilly and more rainy outside. Last week I wrote a blog on my experience and did a full Apple Fitness+ review video, in which I mentioned one of the issues I had was the lack of Cadence sensor integration into the app. Knowing your cadence is really important during a ride because it is your RPM that you are spinning th…

Building a $400 at home DIY spin bike for Peloton & Apple Fitness+

TLDR: I combined the Sunny SF-B1002 Bike, the moofit cadence sensor (now sold out, checkout the Magene sensor), a tablet holder, and gel seat cover to build my own at home spin bike ready for Apple Fitness+ and Peloton digital. In this blog I break down my entire decision process, review the bike setup combined the services, and give final impressions after 2 weeks. I love cycling. I started to get into outdoor cycling after college in Arizona, where I would regularly go out 5 days a week on the…

5 Must Install NuGet Packages for New Xamarin Projects

Starting your first project can be a bit overwhelming. I mean heck, I wrote nearly 3,000 words breaking down every bit of what to select and what each option means. Oh, and I also have a full video series walking you through it step by step on my YouTube channel. Before I start writing code in my projects I take some time to configure my projects and then install essential NuGet packages that help me be super productive from the start. Yes, it is true that Xamarin.Forms and Xamarin.Essentials ar…
