thanks!
1. Ubidrop focuses on getting the technical bits out of the way. The focus is sharing files without having to signin, exchange pin codes or do any sort of pairing.
2. The app works 100% offline. All files are transferred over your local network and nothing is shared over the Internet.
3. Right now I am focusing on nailing the file sharing experience. Not sure what I will focus on next. Those things change as the project evolves.
