Apple on Tuesday updated the official App Store Review Guidelines, officially taking a stance against third-party applications for the Apple Watch whose sole purpose is to tell the time, as first discovered by developer David Smith.
A newly added clause of the agreement guiding third-party development now explicitly states that Watch applications which simply tell the time will be flatly rejected.
“Watch Apps whose primary function is telling time will be rejected,” reads the document. Moreover, the same principles appear to apply to custom watch faces and flatulence apps.
It's worth mentioning that these rules have been enforced since the onset as there has never been a single time-telling Apple Watch app, or a fart app, (or a custom face for that matter) available on the App Store.
