GrooveLog

You log a movement and an amount, correct an entry, and set reminders. Cycles run 3 to 6 weeks. Targets use 40 to 60 percent of a repetition or hold reference. The app states that these figures are not percentages of a one-rep max and not a measure of recovery.

Logging, corrections, a local JSON backup, history, reminders and a preview of the next cycle are free, up to three active cycles. Pro saves named objectives across cycles.

There is no account and no automatic cloud sync. The journal stays on the device.
