Camera Ruler Pro

About Camera Ruler Pro Android App

Camera Ruler PRO is the first app in the android market that allows you to take a picture of an object, accurately measure the size of it, annotate and save the measurement into a picture so as to share with friends or for your own records. This PRO version provides more comprehensive functionality than the free version, and is free of ads and watermarks. The current version supports coins in US dollar, Euro, and Canadian dollar.

Some tips for accurate measurement:
1. Place your item on the ground or a flat / level surface such as a desk top. Place the coin next to or on the item.
2. You can also hold the item vertically, and place the coin on or next to it.
3. Hold your camera parallel to the item. Keep the item and the coin at / close to the center of the camera's field of view.
4. Pay attention to the level at the lower-right corner. Tune it to the center by slightly rolling your phone. The level dot will turn green when centered.
5. The app will try to find the coin automatically. Once it finds it, it will lock the coin by drawing a red circle on it.
6. If the app is not able to lock the coin, please try to change a coin or the background. Basically, please try to increase the color difference between the background and the coin. Sometimes, some extra light helps too.
7. Once the coin is locked, tap on the coin.
8. Zoom, rotate, and move the item to the center; measure it by sliding the two red lines.
9. You've made a good measurement!
10. Double-tap on the screen to bring up the menu. You can save it or share it with your friends. You can also choose to change the color of the ruler, or add annotations to the picture. You will be able to browse the saved pictures within the app.
