folks: split the bill

Snap the receipt, drag each dish onto a face, and everyone sees exactly what they owe. No calculator, no arguing over who had the fries. Point your camera at the receipt and folks reads every line: dishes, quantities, prices, service and tax. It reads printed receipts in many languages and currencies, right on your iPhone. When the numbers don't add up, folks says which part to check instead of guessing. You can fix any line or type the bill by hand. Each receipt you snap is also saved to your Photos. Then hand out the dishes. Drag a dish onto someone's face to give it to them. For a plate you shared, tap everyone who had some and drop it on any of them: each pays an equal part. Service and tax come from the receipt exactly as it prints them, and everyone pays them on their own dishes. Add a tip if you like. Fair to the cent. Every currency keeps its own decimals: yen has none, dinars…
