As long as each item of the tab has quantity, unit price and total price and your camera is good enough, you can take a picture of the tab , and the app will automatically provide you with a digital tab in witch you can mark only the itens you consumed and get the amount of money you must pay, including tips. If the capture is not good enough, it is also possible to add itens manually, what makes the app compatible to almost any device.
