Musklr: Lift heavy. Log fast.
Rep counter, PR & 1RM tracker
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
Log every set and rep in two taps. Know your 1RM. 2,000+ exercises with anatomy diagrams, plus PRs you feel on your wrist. Bulk, cut, or run a 5x5.
Log a set in two taps. Never lose a session. Feel every PR on your
wrist. Built for the gym crowd that takes progressive overload
seriously, knows their 1RM, and runs proper programs.
TWO TAPS. SET LOGGED.
kg on the left, reps on the right. Same column order on iPhone and
Apple Watch. Auto-fill from last week's set, just confirm or adjust.
Numbers stay where you left them. No menus, no friction.
2,000+ EXERCISES. ONE TAP AWAY.
Every lift, every variation, with an anatomy diagram showing the
muscles worked. Squats, bench press, deadlifts, overhead press, RDLs,
dumbbell curls, cable tricep pushdowns, hip thrusts. Filter by what's
free in the rack: barbell, dumbbell, kettlebell, machine, cable.
Filter by the muscle you want to hit. Find the lift, log it.
BUILT FOR BULK, CUT, AND SHRED
Bulk on a hypertrophy block, cut for summer, run a strict 5x5, or
grind a push/pull/legs (PPL) split. Whatever the routine, Musklr
handles it. Track volume per muscle group: back, chest, legs, arms.
Watch your physique build compound by compound. Every set, every rep,
every gain logged.
PRS THAT FEEL LIKE PRS
When you lift heavier than you ever have, the watch double-buzzes and
the phone celebrates. Confetti, only when earned. Estimated 1RM
(e1RM), max weight, total volume, top set reps, duration, distance.
Every kind of PR, tracked per exercise and per session, with smart
deduplication so the same record doesn't celebrate twice.
A REAL LIFTING APP FOR APPLE WATCH
Designed for wrist-first. Live heart rate on the active set. Rest
timer that follows you between phone and watch, never both buzzing.
PR celebrations with haptics on both devices, in the same second. The
watch isn't a complication. It's a real surface.
SEE EXACTLY WHAT YOU'VE TRAINED
A live muscle heatmap lights up the muscles you've hit, set by set.
Front and back, in real time. Catch the imbalance before it becomes
an injury: the back angle you skipped, the leg day you keep missing.
PROGRAMS THAT EARN THEIR PLACE
Bring your own routine or follow a curated one. Hypertrophy blocks,
strength phases, custom splits, built once and edited without losing
history. Workouts show you the muscles before you tap Start. Share
with friends or keep them private.
LIFT WITH YOUR PEOPLE (OR DON'T)
Built like a feed, not a leaderboard. Fully optional. Musklr works
without an account at all. If you want to share, your profile gives
you bio, links, recent PRs, and the workouts you actually finished.
Follow friends, like their PRs, drop a comment after a brutal set. Or
post nothing, ever.
WORKS OFFLINE
No account, no internet, no waiting. Lose signal in the basement gym?
Sets queue and sync later. Cloud sync is optional and turns on when
you sign in.
PRO
The free tier is fully functional. No ads, no nags, no paywalled
basics. Pro adds unlimited programs, deeper history and analytics,
and your public lifting profile.
PRIVACY
Your training data is yours. Delete your account from inside the app
whenever you want.

1.231.1 - Buttons in Musklr emails now open the app on your iPhone instead of a web page.
1.231.0 - Your records land on the set that earned them, every exercise card has a ··· menu, and the workout screen stays quick while you type.
1.230.0 - Sign in with Apple shows its progress and says if it failed, and a friend's workout that won't load says so, with Try Again.
1.229.0 - Supersets rest after the whole round, and the Watch saves exactly what you dial with the crown.
1.228.0 - The Apple Watch app redraws far less, and timed sets stopped on the wrist keep their real time even with your iPhone out of reach.
1.227.0 - The Lock Screen and Dynamic Island buttons work without opening Musklr.
1.226.0 - Musklr now needs iOS 17 and watchOS 10; version 1.225.0 keeps working on iOS 16.
