About Ischys Workout Tracker
Ischys is a fast, private workout tracker for lifters. Every set, routine, and personal record lives entirely on your iPhone — no account, no cloud, no tracking. Your training data is yours.
BUILT FOR THE GYM
• Log sets in seconds — weight, reps, warmup, drop and failure sets
• Build routines and start them in one tap, or freestyle an empty session
• A rest timer that keeps running when you leave the app — right on your Lock Screen
• Auto-fills your last session's weights and reps, so you're not retyping
• Personal records tracked automatically: heaviest set, best volume, most reps
APPLE WATCH
• Start a workout on your phone and it runs on your wrist
• Live heart rate and active calories during the session
• Log sets, adjust rest, and end the workout from the Watch
YOUR DATA, YOUR DEVICE
• 100% on-device — no account to create, nothing uploaded, no analytics
• Import your history from other apps (CSV) and export it any time as JSON
• Optional Apple Health: save finished workouts and read your heart rate
OPEN SOURCE
Ischys is open source — see exactly what runs on your device at ischys.app.
