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.
For about the cost of a cup of coffee, RackMath has a one-time in-app purchase that gives you access to these premium features:
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?
A portion of all proceeds from RackMath and all other Happy Lifting Co. products are donated to the Centre for Addiction and Mental Health (CAMH) - because a healthy body includes a healthy mind.
