All in all, the app works very well and is highly customizable. However, it cannot be used in panoramic mode, a major disadvantage compared to other apps. Therefore you either need to invest in a stand or you cannot recharge your batteries overnight. The app crashed several times before I was able to use it. If these two glitches were diminished I would give it a five star rating.
