The set table does the remembering
Last session sits greyed out beside every row and pre-fills the fields. Repeating a set is one tap on the circle. Tap the set number to mark it a warm-up, a drop set, or a set taken to failure. Warm-ups stay out of your totals and your records, where they belong.

What is in it
- 873 exercises, with instructionsSearchable by name, muscle or equipment. Add your own when something is missing.
- A rest timer that starts itselfIt begins the moment you tick a set off. Per-exercise durations, and a notification when it is up, so it works with the phone in your pocket.
- Routines that stay honestSave the exercises and sets you plan to do. If the session goes differently, Kusog offers to update the routine and leaves what you already logged alone.
- Four records per exerciseHeaviest weight, best estimated one-rep max, best set volume, best session volume. Underneath, the heaviest you have ever lifted at every rep count.
- Charts that go back as far as you doEstimated 1RM, top weight, volume and reps over time. Volume by week, and sets by muscle group.
- A streak counted in weeksA week counts if you trained in it. Rest days are part of training, so they cost you nothing.
- Writes to Apple HealthFinished workouts save as strength training, so they count toward your Activity rings. Optional, and everything works without it.
