Impressive claims by the makers: If you take some heavy hitters like Facebook, Facebook Messenger, Instagram, Google Chrome and Twitter you are saving roughly 805mb. Those are almost a garuntee that most people use, but even If you just use one of those apps, ie Facebook, which uses any where from 200mb-400mb+ of space. AppStack™ only uses about 15mb of soace, leaving you with room for a multitude of different things on your phone.
I tried it, looks good. Though slight difference in look and feel of native versus through this app.
