PowerLine is a utility application developed by Urbandroid Petr Nálevka, available on Android platform for free. The app provides smart indicators in the status bar or anywhere on the screen, ready to use with features such as Battery, CPU, Memory, Signal, WiFi, Phone usage, Bedtime alert, Storage, SMS, Missed calls, Network usage and more. With the latest update, the app now offers indicators on the lock screen and navbar with Accessibility service.

The application offers a simple yet effective design with an option to have any number of indicators on the screen simultaneously. The app also includes an auto-hide feature in fullscreen. The free version of the app comes with two indicators, while the PRO version offers more. Additionally, PowerLine allows users to create their own indicator with Tasker. However, the app may ask to enable its Accessibility Service to draw indicators over the navbar and lock screen if the user decides to use the cheating protection feature. It is important to note that the service is only used to show the indicators in the areas that are normally inaccessible for an app and does not collect any personal information.
