3m downloads :) I put a lot of features for free so could optimize earnings more
Over the years I’ve learned a lot about long-term app maintenance, cross-platform challenges, and keeping codebases alive, shifting frameworks, database migrations and OS updates.

Fast forward 12 years, that simple timer has grown into an ecosystem: Android, iOS, Wear OS, Apple Watch, and a coaching platform. All built solo, with no AI assistance, and redesigned 4 times to keep up with UI trends.
In 2013, I couldn’t find a decent interval timer for my workouts on the Android Market (Google Play wasn’t even called Google Play yet!). Could you believe that? Typing 'interval timer' returned nothing! So I decided to build a simple App while in college.
I spent 12 Years Building an Interval Timer App. 🧵

Upgraded the screenshots of TidyLegend. From now on I am focusing on the Benefits not the features. Makes a massive difference. Try it!
