As an iOS developer, I always feel the lack of simple app to check position of objects/elements in any picture or screenshot. Now it's very easy to find position and size of any UI element, specifically x/y position and width/height/size.

This app is specially designed for making Mobile Quality Assurance Engineer (QA Engg.) life much easier. Now they can quickly review Mobile UI with point & pixel perfect dimensions within minutes.

Step1: Take Screenshot of the app to debug it. This will automatically be saved to your Camera Roll -> Screenshots album.
Step2: Open Screen Ruler app and you can see your recent screenshot, enable ruler and straight line frame.
Step3: Check your screenshot dimensions and UI element positions by zooming in/out and using rulers and line frame.

Other fantastic features of Ruler app:
- 4 Sided dynamic ruler. You can also adjust ruler position using your finger. Long tap for more options.
- Free hand ruler scale. It can also rotate to check angles.
- Straighten line frame.
- Long tap & move on screenshot to show RGB color values of any position.
- Multi-feature crop too.
- Change Aspect Ratio.
- Screenshot Resizing.
- Change Device Scale Factor.
- Double-Tap, Pan, pinch gestures to zoom and move pictures.

Download to see how QA engineers accelerating their business by reducing time to check pixel measurements.

Measures pixels between two points in an image

This exactly what I needed to measure the distance between two isobars on a weather map. Having the angle between the two points is neat.
One possible improvement would be to have a measure tool that returns distance (and angle) instead of reading off a ruler.

I have no idea what the units of measurement are. Pixels? Mm? Certainly not cm or inches, which is what I was looking for. I wouldn’t have even thought to rate this if it hadn’t left me with such confusion. Any sort of labels would’ve changed this to no review, or even a four star. But I’m just confused. Which is disappointing.

At least you can upload images of your actually screen, which is more than I can say for the last app I tried. That’s keeping this from a one star.

Not ready for Primetime

First time you open this app, it remains on. No off switch. I'm not sure if the measurement is in pixels or whatever. I can't use this.
