Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Improved the widget's readability and accuracy. Device names, elapsed times and other text now use the same color as the battery percentage (black in Light Mode, white in Dark Mode). Tapping anywhere on the widget now opens the app and refreshes to the latest values. We also fixed cases where the widget and the app showed different battery levels or elapsed times.
