ZeroLog: Offline Gym Tracker

ZeroLog is an offline gym tracker built for people serious about lifting, not social media. Log workouts, track PRs, and see your real progress without an account, cloud sync, or subscription.

WORKOUT LOGGING
Log every set in seconds. Weight, reps, and set type with one tap. Pre-fills your last session's weights automatically.

REST TIMER
Auto-starts after every set. Customize rest time per exercise — 60 seconds for curls, 3 minutes for squats.

AUTO WARMUP SETS
Tap once to generate 3 warmup sets at 40%, 60%, and 80% of your working weight.

PERSONAL RECORD DETECTION
Automatically flags new PRs mid-session with confetti and vibration.

MUSCLE VOLUME ANALYTICS
Weekly volume by muscle group — push, pull, legs, arms, core. Built-in push/pull balance warnings.

EXERCISE LIBRARY
500+ exercises with cloud search. Create custom exercises with bodyweight and cardio support including full treadmill tracking.

POCKET LOCK
Lock the screen mid-workout so nothing gets tapped in your pocket. Hold to unlock.

WORKOUT RECOVERY
If the app closes mid-session, pick up exactly where you left off.

100% OFFLINE. PRIVATE BY DESIGN.
Everything stays on your device. No account, no tracking, no subscription.

ZeroLog is free. A small banner ad appears during rest periods only.
