What Lifters Are Saying

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.

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. This app is very useful for any lifters whether they are just starting or have been in the powerlifting world for years; to quickly put the number in and for us powerlifter to do less thinking and more gripping and ripping.
