Didn’t know I needed this app
Been lifting for a while now and still have trouble calculating what plates to use. This makes life at the gym so much easier, I never have to worry about miscalculating again. And it's more than calculating plates, there’s also neat info hidden around the app like learning about wilks and RPE I wish I could give this more than 5 stars! And free, I would definitely pay for this app.

Love this app
Out of the different calculators and bar loaders out there this app ranks the best. It’s super easy to use, i like the plateau tab because there’s solid info there. I like the estimated max and meet prep a lot (even though I don’t compete in powerlifting I like how I can gauge my sets and reps). I like the interface too. Overall it’s simple, straight to the point, and a great tool plus it’s a got a little sense of humor

Amazing App!!!
This is one app I would definitely recommend to any competitive strength athlete. Easy to use and simple. I thought this was just a weight conversion app but it is much more than that. It takes everything into consideration including weight conversions, meet advice, rpe calculator, etc. All in all a great app and well designed.

Better than the rest
I have been a lifter for years and I have never quite found an app that can help me with my weightlifting journey. This app is very useful for any lifters whether they are just starting or have been in the powerlifting world for years. I definitely recommend this app.

Id use and suggest to other powerlifter
During weightlifting sessions, primarily powerlifting, in powerlifting gyms with kilo plates, I’ve struggled to calculate the weight on a bar. Stepping into certain gyms, like mount Vernon, they have sheets up that say “4 reds and a silver = this amount of weight” so this app is pretty useful and fulfills it’s purpose; to quickly put the number in and for us powerlifter to do less thinking and more gripping and ripping.

Best app even for beginners!
I just started training with weights. It’s being a struggle understanding the change of weight but this app makes it easy peasy. Would totally recommend for someone just starting to train and needs a double check to their math.
