Sarah Perez, writing for Tech Crunch:

Apple today has made a big change to its suite of native applications for iOS devices, like Mail, Stocks, Compass, Calculator, Watch, Weather and others: it’s now making these available as standalone downloads in the iTunes App Store. What that means for end users of iOS devices is that the majority of the stock apps that come pre-installed can be removed. This puts users in more control of their devices.

Yes: you can now remove the Stocks app from your iPhone, among others.

That might explain Kirk’s problem. But I am still puzzled by the difference between Find My Friends and Stocks pointed out in that post.

One suggestion from reader Robert Gaugl:

Find my Friend was a separate download in older iOS versions. So you downloaded it back then. With iOS 7 (8) Apple implemented it in iOS. It’s not available in the App Store anymore, but it’s still listed in My Apps because you downloaded it back than.

Interesting.
