**Overview**

Previously, step tracking was based on Google Fitness. Now, users can utilize their phone’s built-in sensors for more precise step tracking. This guide explains how to switch settings and key considerations when making this change.

###

### Additional Permissions

Using phone sensors for step tracking requires the following additional permissions:

* **Foreground Execution Permission**: Required for real-time and accurate step tracking.
* **Notification Access Permission** (optional): Used solely to prevent step tracking from stopping unexpectedly. This permission is never used for other purposes.

  * *If this permission is not granted, step tracking may stop. We recommend either running the app periodically or enabling the permission for uninterrupted tracking.*
