About
Estimate your one rep max (1RM) from any set. Enter the weight and reps you lifted, add RPE if you track it, and get your estimated max in seconds. 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.
