I wouldn't buy this until it has been updated (I got the Aug 19, 2016 version). Not one star rating because it's a great concept, and is fairly stable on desktop. However, it works horribly on mobile. The filmstrip gets stuck and won't swipe, sometimes you have to double-tap an image to get it to load, sometimes tapping and double-tapping won't load an image at all. Mixed bag of defects on iOS vs Android. Very buggy! I left feedback, but the programmer skipped over it and didn't address. I really want this one to work, but it was half-baked and poorly tested upon release!
