Avoid this one
I should have gotten the free version to test it out with the iPhone 6. But it had lots of good reviews. The app is extremely buggy in iOS 8. The clock itself isnt very large. The backgrounds are okay, but there should be a way to turn them off. Loading your own backgrounds is a tedious process if you have more than a few. And I couldnt delete them after they were added; the app would turn off the delete function each time I tried.
I want to like this app (especially since it cost 3 bucks). But it needs a lot of work.
