FEATURES - 1RM calculator with optional RPE: reps left in the tank are counted, so 10 reps at RPE 7 is treated like a 13-rep max - Transparent formulas: your estimate is the average of Epley, Brzycki (up to 12 reps), Wathan, and Mayhew - Estimated rep maxes from 2 to 12 reps, each shown as a percentage of your 1RM, for planning working sets - Save results to your history by exercise, including your own custom exercises - Edit or backdate saved records - Export your history as CSV - kg or lbs, light or dark theme - 9 languages - No account needed: your records stay on your device PRO - 1RM progress chart for each exercise - Rep max table with your best recorded set for each rep count - No ads Pro is available as a monthly or yearly subscription, or as a one-time lifetime purchase. Subscriptions renew automatically until canceled in your store account settings. Your 1RM is an estimate, not a tested max. Estimates are most reliable at lower reps.
