GainLog: HIT Workout Tracker

GainLog is a workout tracker built for people who actually lift. No flashy animations. No AI coaches. No social feeds. No subscriptions. Just a straightforward tool to log your workouts and track your progress over time.

BUILT FOR FLEXIBILITY Everyone trains differently. GainLog lets you start a workout and add exactly the exercises you want, in any order — no templates to set up first. Whether you follow a strict program or freestyle your sessions, the app adapts to you, not the other way around.

KEY FEATURES

• Log workouts freely — add any exercise from your library on the fly
• Build your own exercise library, organized by muscle group (Chest, Back, Shoulders, Arms, Legs, Core)
• Track sets, reps, and weight for every exercise
• Rate your form (Meh, Good, Perfect) to track more than just numbers
• View progress charts showing your strength gains over time, per exercise
• See your previous workout data right below each exercise — never forget where you left off
• Add personal notes and form cues to any exercise
• Auto-save drafts so you never lose an in-progress workout
• Performance Evolution view — filter your whole training history by muscle group
• At-a-glance home stats: workouts per week, strength trajectory, and muscle group progress
• Export all your data to CSV anytime
• Import data from CSV backups, including backups from older versions of the app

YOUR DATA, YOUR CONTROL All your workout data stays on your device. There are no accounts to create, no cloud syncing, and no servers collecting your information. Want a backup? Export to CSV with one tap. Moving to a new phone? Import your data right back in.

DESIGNED FOR THE GYM Quick input fields let you log sets fast between exercises. The interface stays out of your way so you can focus on your workout, not your phone. Jump between exercises with a tap, and let the app remember your position if you need to check something else.

WHO THIS APP IS FOR

• Strength trainers who want a simple logbook
• People tired of bloated fitness apps with features they'll never use
• Anyone who values owning their own data
• Lifters who know what they're doing and just need a place to track it

GainLog does one thing well: it helps you track your workouts with zero friction. If that's what you're looking for, welcome aboard.
