How a session works
Gravlog is a gym set log for one Android phone. You write down the exercise, the weight, and the reps. The log stays on the phone. There is no account.
Start a workout Open a session and add a built-in movement, or type your own name. Each exercise can hold up to 30 sets. A session can hold up to 20 exercises. Enter weight from 0 to 9999, with up to two decimal places, and reps from 0 to 999. Mark a set done when you finish it.
Rest timer After a completed set, a rest countdown runs inside the app. The default is 90 seconds. You can change it in steps of 15 seconds, from 15 to 300. Skip ends the countdown. The timer does not ring after you leave the app or lock the screen.
Last time The next time you add an exercise you have already finished, Gravlog shows the last completed set. That hint is free. It does not open the full history.
