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.

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.

Works great

Easy to use, does exactly as advertised.

Would be nice if you could enter two weights and it comes up with the optimal setup so that switching avoids moving extra plates. Those that work out with a buddy and alternate sets would appreciate that.
