My expectation of apps is to get rid of these artifacts of the past. In most other parts of the world prices are given to you upfront, no tips necessary.

Not only that, but Uber asks you before you even check out if you want to give 10%, 15%, 20%, 25%, or a custom amount. Considering I haven't gotten my food or service yet, how the hell am I supposed to know? I don't want to deal with this decision. You tell me how much I'm supposed to pay and just present me one number. I'll hit "buy" if it fits my budget.

Uber got rid of cab driver run-arounds, they can get rid of tips in the same way and just ask for a fair price upfront. As a customer I would find up-front, no-tip pricing a MUCH better UX.
