Loop for iPhone is a sleek, attractive app loaded with features to create short animations that you can then save and share with friends and family on the go. While it's not a full-blown movie creator or video editor, it offers plenty of features to create hand drawn animations on your iPhone, and with numerous steps along the way to help you get the most out of the app and a very polished interface that looks great on the small screen, it's a joy to use.
After installation, you can open Loop for iPhone and start creating new animations right away. The app doesn't provide a lot of guidance here so you'll need to sort through a handful of tools before you can really get the full benefit out of this app, but they are intuitively placed for a short learning curve. Draw on the screen, move the frame marker up, and change the drawing. At any time you can press "Play" to see how your animation looks, or you can import images or video to use in the animations. You can change the color of your pen, erase easily, and move between frames at any time. All of this works smoothly and looks so good in that iOS 7-style, flat interface that it's a lot of fun to play with.
Loop for iPhone is a well-made app that doesn't try to do too much and succeeds nicely because of it. The app is free to download and use, though there are some options you can upgrade to with a fee. These are unnecessary to enjoy what Loop offers, though.
