  • This app hasn’t received enough ratings or reviews to display an overview.

Imported routines now match what you actually train. If you brought your history over from Strong, the routine we build from it looks at every session instead of just your most recent one. No more leg days without squats. A clearer app, screen by screen. Programs, Records and Muscles are calmer and easier to scan. The theme picker finally shows you what each theme looks like instead of three coloured dots. Setup, your way. Everyone gets the setup wizard once, so you can pick your units, bodyweight and Apple Health exactly how you want them. Fixes. A set can no longer be logged with zero reps. Your set count stays visible while you type. And if your email needs confirming, the app now tells you so instead of quietly bouncing you to the sign in screen.
