The strength tracker that stays on your phone.
Log sets, estimate your 1RM, and calculate plates in seconds. Maximus runs fully offline — your training data never leaves your device.
Built for the barbell, not the feed.
Three tools lifters actually open every session — no clutter, no noise.
Watch your numbers climb, exercise by exercise.
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.
Never guess a loadout again.
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.
Plan your training percentages instantly.
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.
