This app is not for casual users. It has advanced editing capabilities that once you learn how and when to use there are no limits to what you can accomplish with it. This app pushes the limitations of your phone, so yes, at times it crashes. You have to be patient with it and let it work. Shut down other apps, and wait for it to update itself when you change a setting. Its well worth the extra effort to do some amazing edits. Im a professional photographer and a photoshop professional... This app is great, and a lot like the photoshop plugin by the same company.
