Per-side plates for every set — in kilograms or pounds.
04
Rest timer
A wall-clock rest timer between sets — it self-corrects after you background the app.

Optional account sync — restore your training history on a new phone. Off by default.

Your data

Local-first, by design.

Signed out, nothing leaves your phone. IronLifts works fully offline and stores your training entirely on-device. There are no accounts required, no analytics, no ads, and no third-party trackers.

Sign in only to back up. If you choose Sign in with Apple or Google, we store just enough to sync your own data across your devices — and you can delete your account and everything in it from inside the app at any time.
