Hey Product Hunt 👋 I'm Gero, the solo developer behind gainzy. About a year ago I was paying €6/month for a workout app just to see my own PR history. Not for a coach. Not for a program. Just to access data I had already created myself. I thought that was wrong. So I spent the last months building the alternative. gainzy is a fully native SwiftUI app — no cross-platform shortcuts, no cloud backend, no account. Everything lives on your device. I built it because I wanted something that treated analytics as a basic feature, not a premium one. The full feature list is genuinely free. Apple Watch, Dynamic Island rest timer, volume charts, PR tracking, iCloud backup, CSV export — all of it. I have no intention of monetising this. A few things I'm especially proud of: The "last time" feature — every set row shows your previous weight and reps automatically, so you always know what to beat. It's just super practical mid-workout and I use it every single session. The Dynamic Island rest timer — put your phone down between sets and see the countdown without unlocking. Honestly this started as a gimmick, but seeing it come to fruition was one of the best moments building this. 400+ exercises with muscle diagrams — I wanted a library that's actually complete, not one where you have to add half your exercises manually. I'd love honest feedback, bug reports, or just to hear what features matter most to you. Happy to answer any questions below. Thanks for checking it out. → usegainzy.com
