Buyer Beware! App doesnt work, it is useless!

This app must not be ready for iOS8, it has a flaw that makes it unuseable. When the user goes ointo an option screen such as frames per second, there is no way to return to the previous screen even after making a election. The only way to go back is to close the app and reopen it.
Another thig to consider is that this app does not allow a user to make timelapse with existing photos, which is the reason I purchased it.
Total ripoff! It should illegal to sell junk like this that just doesnt work!
