Cadence Calculator is a free Android app developed by Kukinoid that helps cyclists calculate their cadence. Cadence is the number of revolutions of the crank per minute, which is the speed at which a cyclist pedals or turns the pedals. This app is a great tool for cyclists who want to improve their cycling performance and reduce the risk of injury.

The app is straightforward and easy to use. It provides a simple interface that allows users to input their cycling speed and the number of teeth on their bike's chainring and cassette. The app then calculates their cadence in revolutions per minute (RPM). In addition, the app has built-in help that provides information about cadence and bicycle gearing.

Overall, Cadence Calculator is a useful app for cyclists who want to improve their cycling performance by monitoring their cadence. The app is free to use and provides accurate calculations. The only downside is that it is only available for Android devices.
