This app has absolutely no use. Test it and you'll see that it's totally useless. Tens of scientists of worldwide reputation tried to find it a use, but all their attempts ended in failures so far.
So don't expect anything particular. All its features (none, in fact) are already mentioned in the description. This is the first multi-unfunctional application in the world. Just assume that for anything that any other app does... this app doesn't do it.
The first application really making what it promises: uselessness.
