I have been using this app for years and I've always been impressed by its simplicity and speed. The best feature is the ability to modify the plate value by simply sliding your finger up or down on the screen. This makes it very convenient to adjust the value without typing or tapping. I highly recommend this app to anyone who is looking for a simple and effective plate calculator app!

Thanks so much for the review Micah!
It really is fast

The workout app I am using at the gym doesn’t have it’s own plate calculator built in so I needed to find something to quickly switch to from that to determine my weights I’m wanting (rather than actually trying to do the math myself). The sliding up and down to change the weight value works extremely well, and really can’t think of anything I don’t like about the app.

Thanks for the kind words!
The best tool for my power lifts

Plate calculator is a valuable asset to my workout routine that I had yet to find before it was recommended to me by a friend. It's extremely helpful to figure out exactly what I need, and it's easy accessibility and usage are more than worth the price. Fantastic app, would recommend to anyone looking for an easier way to keep track of their workouts.

A barbell calculator that actually saves time

When my mind is cloudy from endorphins and all of my blood is in my muscles, this app spares me the mental math and keeps me focused on my training. Every other barbell calculator I’ve tried is janky and takes me out of the focused state I want to be in at the gym.

Haha that's the goal! Thanks for the review.
Minor fixes and improvements.
