It would give it 5 stars if the temperature would show its decimal places. Example; 38.3 Celsius and not just 38 Celsius. It's a small difference, but it's very important. fix battery temp overlay please. updated: We sincerely appreciate the update and improvement implemented in the display of battery temperature, which now includes decimals. We greatly value your attention to our comments. 5/5 stars

Thank you for your review. Regarding the integer temperature display, we currently show only whole numbers to save display space, but we recognize that this is insufficient for observing minor temperature changes. We will address this in the next update. Thank you for your continued support of Usage Overlay.

It does what it says. But an option to display the top resource hogging processes would be nice.

Thank you for your review! I’m glad you’re enjoying the app. Showing resource usage for individual apps requires system-level access that regular Android apps generally don’t have. This app also keeps permissions to a minimum, so I’m unable to offer this feature. Thank you for understanding.

Really cool app, would be even nicer to use if registered a quick action to show the overlay form them quick panel, or an app action so it could be started from OneUI routines
