Nope, it's an everyone young people under 25 (or so) thing. The payments holy trinity is Venmo, Tab, and Splitwise. Tab is for splitting specific checks with easy itemization and multi-person selection + easy tip calculations, connects with Venmo. Mobile app only. Splitwise is great for running tabs, traveling in groups, or complex splits. Keeps track of who paid and who split and even simplifies to the fewest number of payments, of course also done by Venmo. Great desktop site with a good mobile app as well. The only thing I'm waiting for is to import a Tab bill into Splitwise!
