Log sets, estimate your 1RM, and calculate plates in seconds. Maximus runs fully offline — your training data never leaves your device.
Three tools lifters actually open every session — no clutter, no noise.
Every logged set feeds a live estimated 1RM for each lift. See your trend line over weeks, compare exercises, and know exactly where you stand before you touch the bar.
Type in a target weight and Maximus works out exactly which plates go on each side. Configure your bar weight and the plates you actually own, down to the micro-plate.
Enter any weight and rep count to get an estimated one-rep max, then see it broken down into Max Effort, Heavy, Strength, Hypertrophy, and Volume percentages for programming.
Maximus ships fully localized in six languages, with more planned.
No subscription, no recurring fees, no account required. Pay once and Maximus is yours on every device you own.
We're opening a limited beta ahead of launch. Sign up and we'll email you the moment a build is ready to test.
