Get the app

Put FitMathHub on your home screen. It opens like an app and the calculators work without a connection, at the gym or on a run. Free, no account, no app store.

If your browser shows an install option, the button above does it in one tap. Otherwise follow the steps for your device below.

Save every calculator for offline use

The calculators you open are kept for offline use automatically. To have all of them ready before you lose the connection, download them once now: about 2 MB.

  2. Tap the menu (⋮) and choose Install app or Add to Home screen.

iPhone and iPad (Safari)

Computer (Chrome or Edge)

What the app does and doesn't do

  • It's the same site, in its own window, without the browser bars.
  • Your numbers stay on your device, exactly as on the website. There's no account.
  • Calculators you've opened (or all of them, with the button above) work without a connection.
  • To remove it, delete it like any other app.
