Most lifting apps make you start a workout, follow a session, track rest times, and finish before your lifts are saved. Lift Log is different. Open the app, pick a lift, enter your sets, done. Your history saves automatically so you can track strength, volume, and progress over time — without ever starting a "workout." Built for lifters who want a clean logbook, not a complicated fitness app. WHY LIFTERS LIKE IT • No workout mode, no timers, no clutter • Log sets, reps, and weight in a few taps • Browse your history on a simple calendar • Progress charts: estimated 1-rep max, top set, and volume over time • Suggested surfaces lifts you haven't trained in a while, by body part • Add your own custom exercises PRIVATE BY DESIGN • No account, no sign-up • All data is stored on your device and never leaves it • No ads, no tracking, no analytics • Export your data anytime as a JSON backup, and import it back Just log your lifts. See your progress. Never start a workout timer again.
