Focus on working out - not the math.

 

We don't know about you, but trying to do plate calculations in our heads after grinding our way through a set...no, thanks. So we set about creating an app that would handle all your barbell math. We also knew not everybody has the same set of weight plates hanging around, so we included a customizable inventory to match the equipment that's available to you.

RackMath is FREE to download on iOS and Android.

Increased plate quantity - each plate denomination increases from 8 to 16

Customizable bar inventory - set your bar weight to whatever you desire; or use a dip belt, EZ curl bar, hex bar or leg press

Reverse calculator - put the plates on first and then total up the weight

Rep range calculator - using various formulas, see your estimated rep range from your 1RM to 30 reps

Percent change - easily change your lift weight by a percentage amount

Percent table - great for warm-up sets and pyramids

Unit converter - convert a weight from lb to kg and vice-versa

Collars - customize and add collars to the calculations

No ads - obviously, right?
