On-screen Ruler APK for Android

On-screen Ruler is a useful utility application designed for Android devices, allowing users to measure objects directly on their screens. This free app creates a floating ruler that can be used for both digital and physical measurements. It offers the flexibility to switch between measurement units, including centimeters and inches, making it suitable for various tasks such as UI testing and design work. The app is easy to set up, requiring only permission to overlay other applications, after which users can immediately start measuring.

The On-screen Ruler features a simple interface that enables users to slide the ruler across the screen, providing a customized measuring experience. Users can also adjust the color of the ruler's markings, although options are somewhat limited.
