Body Builder is the no-nonsense workout tracker built for serious lifters. Log every set, chase personal records, and study your progress — without subscriptions, accounts, or distractions. Your data stays on your phone, always.
TRACK EVERY SET
Organise exercises by category and log weight, reps, and rest time for each set. Body Builder calculates your estimated one-rep max as you go, ranks your best lifts all-time, and flags personal records the moment you earn them.
WORK WITH PERSONAL TRAINERS
Print out your recent activity or create a pdf to send to your personal trainer.
STUDY YOUR PROGRESS
A 1RM line chart for every exercise shows your strength over 1, 3, 6, and 12-month windows — automatically rescaled so real improvements don't look like flat lines. See your top-10 all-time lifts, season bests, and session volume at a glance.
SET YOUR SEASON
Create a. customisable season and recognise personal bests and progress within the season as well as across all time.
BODYWEIGHT EXERCISES
Pull-ups, dips, and ring work log naturally. Mark any exercise as bodyweight and the app tracks extra load separately, syncing with Apple Health to calculate total weight lifted.
WORKOUT HISTORY
A full calendar view shows every training session at a glance. Tap any date to review the complete log — weight, reps, and estimated 1RM for every set.
REST TIMER
A persistent floating timer keeps your rest honest. Set your preferred duration once and the timer sits above any screen until you're ready to go again.
