About RackMath Barbell Calculator
When weightlifting, you want to focus on your workout. You don’t want to spend time calculating which weight plates you need to load onto your barbell. The RackMath barbell calculator is the simple solution to this problem. It calculates what weight plates you need to load onto your bar to achieve your desired weight.
Quick:
Stop doing the math in your head. The plate calculator will do the math for you. If you are into weightlifting or powerlifting and consistently perform heavy lifts like the squat, deadlift and bench press, then you won’t find a better weight plate calculator. Simply enter the weight you want to lift, and instantly you’ll know how to load your bar. It makes a perfect companion to weightlifting programs such as Starting Strength 5x5 or Jim Wendler’s 5/3/1.
Safe:
Don’t step into the squat rack with the wrong weight by accident. You can count on the RackMath barbell calculator to make sure you’re loading your bar correctly.
Customizable:
Other weightlifting plate calculators just assume you have certain plates and unlimited stock. We know that’s simply not true. This is why Rack Math is designed to let you set your own equipment inventory. Select pounds or kilograms and choose which weight plates (and how many) are available to you.
Fractional and non-standard weight plates:
Other weightlifting calculators do not include fractional plates or lesser used weight plate denominations. RackMath's inventory offers fractional plates as well as a large number of denominations.
RACKMATH PREMIUM* FEATURES
More bars:
With RackMath Premium, you get access to a variety of bars so you can move beyond the squat rack - use a dip belt, hex bar, leg press machine and EZ curl bars.
More plates:
Increase the plate maximum from 8 plates to 12 plates.
More customization:
Have a smaller, lighter bar? Now you can set your bar weight however you desire. Want Rack Math's plate inventory to match your own exactly? Go ahead and customize your plate colors.
Reverse calculator:
Load up your weightlifting bar with whatever plates you want and then see how much weight you're about to lift.
Rep range calculator:
Calculate your theoretical lift weight across reps, from your one-rep max to 30.
Percentage changes:
Perfect for pyramids and warm up sets, you can quickly increase or decrease your weight by any percentage you want.

This is a good app for a small price. However, it's a real shame that you cannot truly customise the plates. True, you can change the colours but you can't change the weight - which is what you have the app for in the first place. For example, I have 0.125 kilo micro plates but the smallest option on this app is 0.25 kilo, so the app won't help me at all with micro loading correctly. It seems like a massive oversight because I would guess a quick bit of coding would allow you to create custom plates in the app. For that reason it misses a star for me, but hopefully they will make it so you can actually customise your plates in the future. Other than that it's good.

Once purchase for a very very small fee this app is the best weight plate calculator you will very find. Choose from Lbs and Kg change the bar weight, tell the app what weight plates you have avaliable, tell it the total weight you want for the exercise and BOOM!!! It does it perfectly. Well done developers this is just what my thick lazy brain needed.

Best App of its kind in the store!! The user interface is also really easy to follow! Free App is great but I upgraded for the small fee and haven't looked back.

Bright battery wasting theme, the worst inventory system I've ever seen (you must select 2,4,6, or 8... no infinite option for gym use, no custom options have fun on leg press day!), only two bar options, also without any custom sizes. One of the worst plate apps in the store.

This app is great. It would be perfect if you could change the weight of the barbell. Mine weighs 40 pounds so this app isn't usable for me right now. *Edit* - Great! Just upgraded and changed my review to 5 stars. Thanks!
