RackMath Barbell Calculator

Pay to use

Just use chatGPT instead. I wanted something that would help me keep up with what weight is on the bar. Everything you tap on is “upgrade to premium”.

Has helped me stay focused on gains. I use this app almost every workout, I start by using it for my warm-ups and then for my lifts. I bought the premium upgrade which is really nice for converting to KG and seeing percentages of my working weight for warmups. I wish it had a dark mode, but it does what it is supposed to well.

If every option is going to be an upgrade just be honest about it. I got this thinking that I could use it to calculate the plates I needed. Everything was a premium upgrade. Obviously they just care about the money. Keep moving on….

Great for the free version but gotta say I had hoped paid would have more features.

I recommend this app to all of my lifting buddies. It’s so simple, so clean, make my lifting life better. Thank you to the dev for a great product, at a very reasonable price -Dennis

Love how you can enter in the weights you have and the app uses those to provide you with the easiest way to load the bar for that number. Less mental work while lifting when tired.

This is a great product. It does everything you’d want it to. The feature that allows you to tell the app which weight plates you have is particularly helpful—that way it only suggests combinations you can actually put together what what’s on hand.

When I’m in the gym, it’s hard to think about the math. This app is so easy to use I can stay focused on my lifts.

Most importantly, this is an amazing app. The ability to calculate 5/3/1 percentages (using 90% of your 1RM for your training max) is very useful. One suggestion for a streamlined experience, as someone who calculates many weights at a time, instead of having a pop up that tells you how much weight has been rounded off (that you have to click away), implement that weight into the screen somewhere.
