Your gym log.
Yours alone.
BettyGym is a quiet workout logger for strength training. Record sets, watch progress, and keep every kilo on the device in your pocket.
Inside the app
Home, logging, statistics, and profile — the four screens you live in.
Built for real sessions
Ten starter lifts — squat, deadlift, hip thrust, and more — plus any custom movement you add. Empty logs on day one. You fill the history.
Favorites first
Keep the lifts you actually do at the top. The rest of the list stays collapsed until you need it.
Weekly progress
See workload and sessions by week, month, or 3 months — plus progress on a single movement.
Simple profile
Name, height, weight, and BMI on device. Edit anytime. No account to create.
Backup & restore
Export a JSON backup or a CSV of logs. Import the same files back into the app if you switch phones.
Offline by design
Everything lives in SwiftData on your iPhone. No cloud, no ads, no tracking pixels.
How a session looks
01
Open Home
Favorites on top. Expand All Exercises when you want a new lift, or tap + to add your own.
02
Log the work
Sets, reps, and a kilo field for every set. Workload is reps × kg, summed. Intensity is a simple percentage.
03
See the week
Statistics charts compare this period to the last. Long-press a log if you need to edit it.
Coming to the App Store
A private gym log for iPhone. No account, no cloud — just your lifts on your device.
