## What is Sinew?

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.
