I've been lifting for 10+ years and I have never been truly happy with any workout tracker so I have been using Google Sheets until I made my own.
Splitt is a native iOS app (SwiftUI + SwiftData) that does one thing: tracks your sets across training sessions. No account, no AI, no social. Your data stays on your device.
The live activities are actually useful as you can log all your sets + see your rest timers directly from lockscreen.
Not coming out with a groundbreaking product here, just making something I use myself.
