Show HN: 12 Years Building an Interval Timer App

[melvinzammit]

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.

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.

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.

Here's to all the solo indie App Developers out there!

Do you have some screenshots from 2013? It would be interesting to compare.
