This app functions as a one rep max (1RM) calculator and a logbook. It helps you estimate the maximum weight you can lift for a single repetition based on your performance with lighter weights and multiple reps. You can also use it to record your lifts and monitor your strength gains over time.
To calculate your 1 Rep Max, select the type of lift, enter the weight you lifted, and the number of repetitions you completed (up to 10 in the free version). Then, tap the 'Calculate' button to see your estimated 1 Rep Max weight.
