Built for the set you're about to do

No feeds, no streaks, no coaching upsell. Just your plan, what you did last time, and a fast way to write down what you did today.

Track anything by the session

Strength, reps only, timed holds, cardio, bodyweight, body measurements or plain counts. Pick a type and the log fits it.

Last time, at a glance

Every exercise shows your previous session's weights and reps, so progressive overload is a glance, not a scroll.

Machine taken? Swap it

Keep alternatives for each exercise with their own targets. Switch in one tap and keep the history comparable.

Forgot to log? Backfill

Change the day in the header and log into any past session. It turns yellow so you never do it by accident.

Kilograms or pounds

Switch between metric and imperial any time. Nothing is rewritten, so your numbers stay exact.

Your data, your file

Export your whole log as a backup file and import it on another device. No cloud account in between.

Three steps, then just lift

Desktop

In Chrome or Edge, click the install icon at the right of the address bar.

Questions

Is OpenLog free?

Yes. There is no paid tier, no ads and no sign-up.

Where is my training data stored?

Only in your browser on your device. There is no account, and your log is never uploaded. The one exception is the optional AI plan builder: what you type into it is sent to OpenAI to write your plan, and is not stored.

Does it work offline?

Yes. After the first visit the whole app is cached, so it opens and logs in a basement gym with no signal.

How do I move my log to a new phone?

Export a backup file from the menu, send it to the new device, and import it there. Import replaces what was on the new device.

How do I install it on my phone?

On Android or desktop Chrome, use the Install button. On iPhone, open the site in Safari, tap Share, then Add to Home Screen.
