How Pro works

  • Monthly: renews every month until you cancel. Eligible new subscribers get the first week free.
  • Lifetime: a one-time purchase that keeps Pro forever.
  • Both unlock the same Cero Pro. Prices are shown in the app, in your currency.
  • Payment is through your Apple Account, and you can cancel a subscription in your account settings at any time, at least 24 hours before it renews.
  • Restore your purchases on a new iPhone from Cero’s Pro screen.

Over the limit of 2 saved timers? You can keep using the timers you already have.

Cero is a timer, not a medical device. If you’re new to hard exercise, are pregnant or have a health condition, check with your doctor first, and stop if you feel unwell.
