Not just bad. There isn't a single piece of Apple software that is (1) free and (2) people choose to use on iOS, only use because the user is forced to. Photos? Forced, sucks. iMessage? Forced, sucks. Apple Mail, Calendar, Contacts? Huge pieces of shit. The App Store, the very gateway into competition, is the shittiest of all, and not just because the 30% fee, but because its discovery is maybe the worst ever made by any catalog-style front end in the world.

At least they opened up the password completion APIs.
