Is Kohlrabi really free?
Yes. The tracker has no paid tier, no trial and no ads. Optional tips pay for hosting.
Do I need an account, and where is my data?
No account to log. Signed out, data stays in this browser. A free account adds sync and share links via an emailed code. Settings, Data exports a JSON backup and CSV.
Is it in the App Store?
Not yet. Open kohlrabi.us and add it to your home screen; it opens full-screen like an app.
Can I import from Hevy, Strong or MacroFactor, and export my data?
Yes. In Settings, Data, import a CSV export from Hevy, Strong or MacroFactor, or a MacroFactor program sheet (.xlsx), and review the exercise matches before anything is saved. Kohlrabi also imports its own CSV format, restores its JSON backup, and exports a JSON backup and a CSV of every workout. See the import guide.
Does it work offline?
Yes. Once loaded, you can log a whole workout with no signal. With an account, it syncs when you are back online.
How do I install Kohlrabi on Android or iPhone?
On Android, open kohlrabi.us in Chrome, tap More (⋮), then Install and create shortcut. Or tap Install Kohlrabi in Settings, About, when it shows. On iPhone, open it in Safari and tap Share, then Add to Home Screen. See Install the app.
Does Kohlrabi use kilograms or pounds?
Both. Pick Pounds or Kilograms in Settings, Display & Units; a Strong import can ask which unit its file uses.
Does Kohlrabi have a rest timer?
No. Kohlrabi has no rest timer, by design: it logs your sets and suggests your next weight.
Does Kohlrabi work with Apple Health or Google Fit?
No. Kohlrabi does not connect to Apple Health, Google Fit or other health apps.
