StrengthCalc is a gym utility used for beginner, intermediate, and advanced lifters.

If you're having trouble figuring out what your most heaviest lift is in a particular exercise, this is the perfect app for you. StrengthCalc will determine what your estimated one repetition max is, without actually testing it! Save yourself the time of trial and error.

StrengthCalc will show you how many reps you have to lift in order to hit a specific weight. Just input a number into the weight field, leave the reps field empty, and click Rep Maxes. It will show you the required weight and reps you need to lift in order to theoretically hit that one rep max. Let StrengthCalc guide you towards a stronger you! This app will show you the weight you need to lift, in the 2-12 rep range.

If you're an advanced lifter following a specific training program that utilizes percentages of your one rep max, StrengthCalc can tell you those percentages as it will break down your one rep max from 40-95%, through 5% increments. Stop wasting your time calculating each percentage.
