On July 31, the developers of Moves will be shutting the app down. This means it will no longer be possible to track steps with Moves, nor will it be possible to sync steps from Moves to Walkadoo. You can learn a bit more here: https://www.moves-app.com/
Not to worry! If you have an iPhone 5s or newer, or an Android phone, you can switch over to the Walkadoo app to continue tracking your steps.
Alternatively, if you're participating in a sponsored program that's providing a step tracker, you can switch to that device.
A full list of step trackers compatible with Walkadoo can be found here.
