User reviews

Best barbell racking app, if purchase would work…

The features in this app supersede any others I’ve tried! The problem comes after the 7-day trial. The purchase functionality just doesn’t work. The button to unlock full access does nothing when clicked, so the app is unusable. Additionally, the contact form on the developer’s website doesn’t work. Please fix it, man! You’ve got a great app here!

Cool app!

Very cool app for workouts. Gives options for how much weight on the barbell with various plates, and instant calculations on which plates to remove/how many to add for targeted weights. Makes workouts easier.
