Lift. Log it.
Get stronger.
A fast, focused training log that plans your week, tells you when to add weight, and stays out of your way between sets.
No account. No ads. No subscription. Your training data never leaves your devices.
Everything you need in the gym. Nothing you don't.
Built for people who follow a program and want to see the numbers go up.
Weekly plan
Set up seven days with exercises, sets, rep ranges and rest. Today's session is waiting when you open the app.
Automatic progression
Hit the top of your rep range on every working set and the weight goes up next time. Bodyweight moves progress by reps and sets.
Rest timer
Starts by itself when you check off a set, with a notification and haptics when it's time to go again.
Personal records
PRs are detected as you lift. Every exercise keeps its history, best sets and a chart of how far you've come.
Progress
Weekly volume, sets per muscle group, body weight with goal line and trend, body measurements and progress photos.
120+ exercises
A searchable library with filters and favorites. Add your own exercises whenever you need them.
Widgets
See today's workout and your week at a glance on the Home Screen.
Gym tools
Plate calculator, one-rep-max calculator, and kg or lb, your choice.
Bring your history
Import from Strong or Hevy with a CSV file, and export everything again whenever you like.
Leave the phone in your bag.
