Tap through sets with targets in view and rest timers built in.
Track Progress
Every session updates your projections and next-session targets.
Tailored to You
Set your numbers once, then progression adapts as you lift.

Guided opt-in progression
Progression rules are prescribed by the program and selected based on performance, but you retain the final say.
Edit anything
Change a weight, add a set or drop one mid-session. The app guides, it does not dictate.
Cloud Sync
Sync your history & progress across devices.
Program & lift progression charts
See how your lifts progress over time.
Templates
Save the workout shapes you keep coming back to and start from one instead of a blank screen.
Offline first
Every set is saved to your phone the moment you tap it, then syncs once you have a connection. No signal needed to train.
Scriptable
Programs are implemented in a custom language called 'IronScript' with a streamlined editing experience in the web dashboard.
