Screen Ruler is a powerful and indispensable tool for iOS developers and Mobile Quality Assurance Engineers (QA Engg.). This free app allows you to easily check the position and size of any UI element in a picture or screenshot. With just a few simple steps, you can accurately determine the x/y position, width/height, and size of any object.

To get started, take a screenshot of the app you want to debug, and it will automatically be saved to your Camera Roll. Open the Screen Ruler app, and you'll find your recent screenshot. Enable the ruler and straight line frame to start measuring. Zoom in/out and use the rulers and line frame to check the dimensions and positions of UI elements.

Screen Ruler offers a range of fantastic features to enhance your measuring experience. The 4-sided dynamic ruler allows you to adjust its position using your finger, and a long tap provides additional options. The free hand ruler scale can also rotate to check angles. The straighten line frame ensures accurate measurements, and a long tap and move on the screenshot reveals RGB color values at any position. The app also includes a multi-feature crop tool, the ability to change aspect ratio, screenshot resizing, and device scale factor adjustment. You can even use double-tap, pan, pinch gestures to zoom and move pictures.
