Point and Call is a Windows Phone 8 app that uses your camera to read and dial phone numbers. Point and Call can come in handy for scanning numbers off business cards, print advertisements, or even computer screens.
Numbers that are scanned can be dialed from within the app or saved to your contacts. It's a nifty concept to make dialing and saving all the phone numbers you run across.
Point and Call is fairly easy to use. Just line up the printed number in between the focus brackets, focus the camera (either by tapping the screen or half-press the shutter button) and hold your Windows Phone steady.
In a few seconds, Point and Call will read the number and send it to the text box in the upper right corner of the screen. You can dial the number by tapping the "call" button, tap the "text" symbol to send an SMS or save it to your contacts with the "save" button.
Settings cover your Country code, turning on/off the camera light, and other settings to enhance the camera scan. You do have a slider to offset the background threshold of the image to make the number easier to read.
In just tinkering with Point and Call for a short time, it performed rather nicely. Numbers on printed paper scanned rather quickly but numbers on the computer screen took a little longer.
There is a free trial version for Point and Call that has some limitations. The full version is currently running $.99 and you can find it here in the Windows Phone Store.
