How much did you lift last time, and for how many reps? AGERU is a workout log that starts from that answer. Pull up your last weight and reps, adjust only what you want to change, and log the set the moment you finish it. No ads to close, no account to create. For anyone logging their first set, and for anyone chasing their own numbers. It isn't built to compare you with other people β€” it's built for your own training. [Start from last time] Your previous weight and reps are one tap away. Type straight into large input fields, and choose Bodyweight for calisthenics to log it in kg from your body weight. [See the days add up] A 12-week activity map shows which days you trained and how many sets you completed. Open any past session from the calendar and look back on the work. [Know where you stand, muscle by muscle] A radar chart shows strength scores for chest, shoulders, arms, legs, glutes and back, based on estimated 1RM for key lifts and your body weight. Scores are a reference only and do not guarantee physical condition or results. [Find any exercise fast] Search by name, browse by muscle group, or pick from recent exercises. Illustrations show the movement and the muscles it targets. [Keep every small step] See how today compares with last time and when you hit a personal best. Charts track weight, reps, total volume and estimated 1RM over time. [A guide to what to train next] Recovery status per muscle group is estimated from your logged sessions. Treat it as a guide β€” how your body actually feels, including any pain, comes first. [No ads. No account] Start logging without signing up, and never see an ad in the app. Records are saved automatically on your device. They can be lost if you delete the app or lose the device, so please read the in-app notes on handling your data. [Your records survive a new phone] Sign in with Apple to back up your workouts and custom exercises. It's free. Sign in with the same Apple ID on a new device and your records come back. Without signing in, every feature still works with no account. [In your language] AGERU follows your device language. 39 languages are supported, and you can switch anytime in Settings. One set today lifts tomorrow's you. AGERU - Workout Log
