I hope this isn't the highlight of iOS 8.
If you need lots of new features for the sake of features Samsung will have you covered in a few weeks.

I don't see why only Apple has to make this app. There are plenty of great developers out there that can come up with a similar app and also maintain it with regular updates.
Right now, Apple should focus their engineers into making iOS 8 an improved experience instead of making new apps that only a minority of the people would use.
What if this app is a companion to some Apple designed wearable device?
