Checkman is the unique application that helps you test the UI design of any mobile/tablet applications. Screenshot any iPhone/iPad's app and open Checkman to check the photo.

Let us show you how Checkman makes magic:
- Zoom in the screen, and you will see all details of elements in a larger view.
- Check if elements are aligned well together. Drag a ruler to the sides to figure out whether elements are aligned properly.
- Measure paddings and margins to compare with design mockups.
- Measure distances of elements in different units (Px and Pt)
- Measure dimensions of elements (width and height)
- Never miss any color. Just touch and hold your finger anywhere on the screen and witness the magic.
- Show iOS grid to follow Apple's guidelines absolutely
