Could do better
It doesn’t understand that my iPad is on its side and the app is locked in portrait orientation. The white on black is difficult to read. It only lets you add multiples of £5 so sooner or later they’re going to owe you money (the end of term) with no obvious way of getting a refund. It’s MY money and I want it back. For some people a few pounds really matters and the developer should understand that. Thankfully the food at my daughter’s school is so poor that I don’t have to use it very often as she takes a packed lunch in on most days.
