Kaido provide direct integrations to Apple Health, Google Fit and Fitbit activity trackers. 

If you use another health and fitness tracker for example Strava or Samsung Health you can still use this device to track your activity during the challenge. 

To do so, connect your device to your smartphones health application, either Apple Health or Google Fit, before connecting that to Kaido.

Your Apple Health/ Google Fit will then send Kaido a record of your total activities across both devices.
