Workout logger · iOS & Android
repsync
Start the workout. Log the set. Rest. Next.
repsync guides you through a session one set at a time, with big readable numbers and controls you can hit mid-workout. When the bench you need is taken, defer the exercise: it moves to later in the session and the sets you have done stay saved.
In development · not yet in the App Store or Google Play
One set at a time
Captures · Push Day



A gym app should get out of the way between sets, not ask for attention.
Most of a workout is waiting: for the rest timer, or for a machine. repsync keeps the screen on what matters now, the weight and reps for this set, and keeps every set on the phone first. A dropped connection never costs you a set.
It's built on the same stack as Slime Squares: React and TypeScript in a Capacitor app for iOS and Android, with optional account backup to a Cloudflare Worker. The server recalculates every total from the sets themselves.

Still to come
Rough order- Testing on real phones, then the first store builds.
- Editable routines, so you can build your own splits.
- Automatic backup that retries when you're back online.
- Training with friends. The friends screen is a preview for now and nothing is shared.
repsync is in development. This page will link to the App Store and Google Play when it launches.
