Just downloaded and tried it. Unfortunately it's not making use of WiFi Direct, which means that all devices that you want to share from or to need to be connected to the same WiFi network. Not much of a problem for me, but it means you can't use it on the go. :/
I hope the app will be entirely translated later as I'm not able to read Chinese.
And currently when trying to send a file it aggregates all available media files and displays them in one huge list. This doesn't only take a lot of time to load, but is also inconvinient if you're looking for one single picture/song.
