Two-finger protractor with 180 and 360 modes. Offline, no ads.
Simple Protractor is a fast, touch-driven protractor for measuring angles right on your phone screen. Place two fingers along the arms of an angle and read the value in degrees, live, with one decimal of precision. No stylus, no clunky menus, no signup. What you can do: - Measure any angle by placing two fingers along its arms. Simple Protractor draws both arms from a shared vertex and shows the reading in degrees with one decimal place while your fingers stay in contact with the screen. - Toggle between a 180 degree semicircle and a full 360 degree dial to pick the range that matches your workflow, whether that is a workshop cut, a picture frame corner, or a homework diagram. - Keep the last reading on screen after you lift a finger so you can copy the value into notes before the next measurement. - Start measuring the second the app opens. There is no home grid, no wizard, no promo screens. Why choose Simple Protractor: - Fully offline. The app never opens a network socket. - Zero permissions. The manifest declares no runtime permissions, no INTERNET, no location, no storage, no camera, no microphone. - No ads and no advertising SDK. - No in-app purchases and no billing SDK. - No analytics, no tracking, no crash reporting SDK. - Small install size and quick startup on modest hardware. - Clean Material Design surface with automatic day and night themes that follow your system setting. Simple Protractor is designed for woodworkers, DIYers, students, drafters, teachers, and anyone who needs to check an angle without unpacking a physical protractor. Compatible with Android 7.0 (API 24) and newer.
