Starting tomorrow Apple will start enforcing a new rule limiting the length of an app’s name to 50 characters. Additionally, they will start disallowing apps from including “terms or descriptions that are not the name of the app”.
The latter of these rules is probably the most actually impactful and important in terms of cleaning up the App Store. As the length of the names hasn’t really been the problem, it is keyword spamming at the end of the name.
But the 50 character limit is still interesting to consider, so I dug through my App Store metadata cache to see just how many apps would be affected. It looks like only around 9% of apps currently have names that are longer than 50 characters (around 200k).
