Gym Logbook: Workout Tracker

Built for the gym floor: log a set in two taps, never lose a session, insights show what you've trained and which muscles are falling behind. Fully offline.

Gym Logbook is a fast, offline-first weightlifting logbook built for the gym floor — large controls, few taps, and sets that never get locked behind “done.”

START FAST • Empty workout, templates with planned targets auto-filled, or Balanced session from under-trained muscles • Wheel pickers for weight, reps, duration, distance, and multi-param cardio • Duplicate last set in one tap; apply previous-performance hints when you want to progress

TRAIN SMARTER • Exercise catalog with muscle groups, region filters, form guides, and favorites • Supersets (library presets + ad-hoc) with alternating focus and rest timer (Live Activity / Dynamic Island) • Personal records by category and estimated 1RM (Epley) for weight × reps

SEE YOUR HISTORY • Calendar workout history, Insights (summary, weekly chart, muscle-balance spider), and per-exercise progress • Recycle Bin with 30-day restore; Export / Import full backup (JSON or CSV ZIP) • Optional Apple Health export for finished sessions (no calorie guesses)

YOUR ACCOUNT, YOUR LANGUAGE • Optional Sign in with Apple or Google (guest works offline) • Cloud sync for finished workouts when signed in; in-progress stays on device • UI in English, Russian, Armenian, Swedish, Norwegian, Dutch, Danish, Polish, French, and Arabic

Built for gym speed. Local-first so you never lose an in-progress workout.
