It got so bad that yesterday the whole app crashed so badly that it wiped out everything I had had saved on the app - over five years' worth of work! This happened not once, but twice - after being forced to wipe my iPhone back to factory settings and restoring from a backup, it did it a second time, forcing me to do the same process all over again. Since the new operating system, it is buggy to the point where practically every single time you attempt to load a saved layer on to your work the entire app crashes, knocking you back out on to your home screen, and all you can do is keep retrying and hoping that this time it will cooperate and actually let you do it. As of this writing, its last update was two months ago, and it desperately needs to be updated again to coincide with the latest iOS. This has always been my favourite editing tool.
