All calculations and history stay on your device. There is no sign-up, and the app does not ask for your name, email, or health data. LiftCalc is free and shows a banner ad at the bottom of the screen.

Important notice
LiftCalc is a calculator, not a source of training, medical, or rehabilitation advice. Estimated 1RM values are approximations. Use a spotter and proper safety equipment for heavy attempts, and train within your own limits.
