a:gain is the workout tracker built for lifters who care about one thing: getting stronger. Progressive overload is the foundation of muscle and strength: gradually increasing weight or reps over time. a:gain makes tracking this effortless so you can focus on lifting, not logging. LOG SETS IN SECONDS Tap, enter your weight and reps, pick your intensity, and you're done. a:gain auto-fills from your last set so you spend less time on your phone and more time under the bar. Add quick notes like "Drop set", "Slow negative", or "Paused rep" to capture how you trained — not just what you lifted. SEE YOUR PROGRESS INSTANTLY Every session is compared to your previous one. Volume, reps per set, and load per rep are broken down with percentage changes and progress bars. Green means you're improving. It's that simple. POWERFUL ANALYTICS Dive into interactive charts for every exercise. Track average weight, estimated 1RM (Epley formula), and total volume over time. Tap any data point to see a full session breakdown with per-set details and intensity levels. BODY WEIGHT TRACKING Log your body weight and track trends with a smooth 6-month chart. See your current weight, weekly average, day-over-day change, and total progress from when you started. WORKOUT HISTORY & REPEAT Browse your full training calendar month by month. See exactly what you did on any day — then tap "Repeat Workout" to clone every exercise and set to today in one tap. AI COACH ANALYSIS On supported devices, get an on-device AI breakdown of your session: exercise synergy, set pattern detection (pyramids, drop sets, straight sets), strong points, areas to improve, and rest/density tips — all from a virtual strength coach analyzing your actual data. Powered by Apple Intelligence. Your data never leaves your device. ORGANIZE YOUR WAY Group exercises under custom workout types. Run PPL, Upper/Lower, Bro Split, or your own program. a:gain comes preloaded with a Push/Pull/Legs split and 18 exercises to get you started. DESIGNED FOR SERIOUS LIFTERS • Quick set logging with auto-fill from last session • 3-level intensity tracking on every set • Session-to-session comparison with % change • Interactive charts with 1RM estimates • Body weight trend tracking • Monthly workout calendar with clone feature • AI-powered session analysis • Supports kg and lbs • No account required • No subscriptions • All data stored on your device No social feeds.

You can always look back at the motivating process of your body leaning out and your muscles growing bigger in one smooth video. ◆ 3 Features You’ll Love No Login Required, Start Instantly: Start capturing and tracking your progress the moment you open the app. 100% Private & Secure: Your data is securely stored locally on your device.
