Log the lift. See the trend. That's it.

Iron Log is a simple weight-training tracker: log the lift, watch the numbers climb, and get on with the next set. Everything stays on your device — no account, no subscription, nothing sent anywhere. Live now on the App Store.

Get it on the App Store Android coming soon

On-device, full stop

Your training history lives on your phone and nowhere else. Delete the app and it's gone — which is exactly how it should be.

Fast between sets

Logging a set takes less time than racking the bar. No forms, no forced rest timers, no social feed of other people's deadlifts.

The trend, visible

Progress shows as a line you can actually read — per lift, over time — so a heavier bar is something you can see coming.

Strong is a long game.
