I like that you can create different versions of your app, so if one version gets popular it's easy to upgrade later without having too many problems with upgrades or bugs in existing features. The layout is not very intuitive - some things are hard to find even after using them once! There should be more tutorials about how everything works. This was just an example from their site but there were other options as well (that was confusing). If this product seems interesting then definitely give it a try because otherwise I wouldn't recommend it at all! We needed something simple where we could easily upload our application files which would allow us to test out new applications before going live.
