About
Log every set. See last time's numbers. Leave the gym knowing you got stronger.
Sinew is a gym log built for barbell, dumbbell and machine training. It is fast between sets, honest about your progress, and stores your training log in the app on your iPhone — no account, no workout server, no tracking.
FAST WHERE IT MATTERS • Your last session's weight and reps appear on every exercise as you log. • A nudge tells you what to do next: add 2.5 kg, or stay and beat your reps. • Steppers and one-tap repeats — logging a set takes seconds. • The rest timer starts when you finish a set, with +30s when you need it.
KNOW YOUR STRENGTH • Estimated 1RM for every lift, trended over weeks and months. • Session volume, sets and time for the week at a glance. • Personal records are spotted automatically — trophies land when you beat your best.
THE TOOLS A LIFTER ACTUALLY USES • Plate calculator: exact plates per side for any target, or the closest total that exists. • 1RM calculator with the standard percentage table. • 94 exercises with muscle tags and short technique cues. • Routines for your push, pull and legs days. • Kilograms or pounds — switch anytime; your data never moves.
YOUR DATA IS YOURS • Workouts are stored in the app on your iPhone. No Sinew account, workout server or tracking. • Import your history from Strong, Hevy or FitNotes as CSV with Pro. • Export your workouts as CSV with Pro — no lock-in. • Deleting the app removes its local data; exported files and device backups are separate.
SINEW PRO Logging is free, forever, with unlimited workouts and history. Pro unlocks the analysis layer: strength charts and 1RM trends, unlimited routines, RPE tracking, and CSV import & export. One subscription, or a one-time lifetime purchase.
