This app is for when you want to add new contact, but the number is on a bussiness card, pc screen, webpage, or even written on a wall! all you have to do is to pick that image, then scan it for phone numbers it has, list of phone numbers will be displayed, you can then tap on any item of list of phone numbers to go to saving to contacts scree, custom interface than that of default Contact App!
You can also get the image to scan from photo library, then go same process, by scanning it by the app then displaying list of phone numbers and so fourth!
The app is really helpful in the way that, you dont need to write phone numbers yourself, its really headache sometimes, so just let app scan them, you add names to save with, also image will be default the one you scanned!
