Tax and tip are fairly assigned based on the weighted split of items each person ordered. Your friend ordered the surf and turf and you got chicken? They pay more in tax and tip at the end. Using the latest in AI and computer vision, the app provides a live detection of the receipt as you move your camera. Unlike other apps that make you wait and hope the receipt is a good scan, 1split lets you preview the scan as you move the camera, making it easy to adjust on the fly. 1split features include: - Access to all your past receipts - Live group editing: your friends can join the bill on their phone to help split - Importing receipts from your camera roll: 1split will apply a high-resolution scan to images on your phone to detect receipt line items, tax and tip - International currency support: scan the bill in any currency and then send out requests in US dollars (currency conversion happens for you automatically) Privacy Policy https://sites.google.com/1split.com/privacy-policy Terms of Service: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
