SQLite stays the primary workout store, so the app works signed out. Sign in when you want AI, backup, reconciliation, and restore across installations.

06 · Apple Watch

The session
on your wrist.

The companion is not a passive timer. Start a saved workout, adjust weight and reps, complete sets, move between exercises, skip rest, and finish—while the iPhone remains the source of truth.
