Lckdin; Gym & Workout Tracker

Lckdin is a serious training log for people who lift, built to capture what actually happened in the gym, not a simplified version of it.

OFFLINE BY DESIGN
No account, no login, no cloud sync. Your training data lives on your device in a real database, works in airplane mode, and never leaves your phone except when you choose to export it. Full JSON and SQLite export, anytime — your data, not ours.

LOG ANYTHING YOU ACTUALLY DO
Straight sets are just the start. Log drop sets, rest-pause, clusters, myo-reps, mechanical drops, and left/right unilateral work. Group exercises into supersets, giant sets, circuits, complexes, pyramids, EMOM, AMRAP, and interval blocks — with a full-screen timer for Tabata, EMOM, 30/30, and custom ladders. If you can do it in the gym, Lckdin can record it.

BUILT FOR SPEED IN THE GYM
Logging a set is two taps. Nothing blocks the screen waiting on a calculation — the app stays fast between sets, every time.

TEMPLATES AND SPLITS
Six built-in training splits with full day-by-day templates, or build your own. Starting a workout copies your plan into the session automatically, with progression rules applied — so your history stays exactly what you did, even after you change the plan going forward.

DEEP ANALYTICS
Over 85 statistics across volume, strength, records, consistency, muscle balance, recovery, and body composition. A full-body muscle heatmap shows what's been trained and what hasn't. Personal records are detected automatically and preserved correctly even if you delete a session. Every chart supports period comparison and CSV export.

PHYSIQUE TRACKING, PRIVATELY
Track body measurements and progress photos with pose guides and a compare slider. Photos stay in the app's private storage — never your camera roll, never a cloud album — with an optional biometric lock on top.

LCKDIN PRO
Most of Lckdin is free, permanently. Pro ($2.99/month or $19.99/year) removes the occasional video ad and unlocks a set of specialist statistics for advanced analysis. Banner ads remain for free users to support development. Subscriptions auto-renew until cancelled; manage or cancel anytime in your App Store account settings. No free trial. Terms of Use and Privacy Policy are linked in Settings.

Lckdin doesn't track you, doesn't sell your data, and doesn't need an internet connection to work. It's a logbook, not a platform.
