My home screen widget isn't updating. How do I fix this?

On some Android devices, battery optimization settings can stop widgets from updating properly.

Try the following:

  • Disable battery optimization for Chrono91
  • Allow background activity

Xiaomi / HyperOS devices (common fix):

  • Go to Settings > Apps > Manage apps > Chrono91

Once these settings are adjusted, the widget should update normally.
