Duets.fm is an unofficial, third-party app for Smule™ singers. It downloads the songs you sang and the associated metadata from Smule.com to your mobile device, on your behalf.
The app is built around your safety and privacy. It reads only the publicly available information from Smule™ and does not ask you for your Smule™ credentials. This means that the app cannot post songs, read or write comments or access private songs in your Smule account. The app also makes sure that no one else but you, can use this app, on your Smule™ account by making you enter a random code in your Smule profile.
Duets.fm is developed and maintained by QuantumBytes LLC, a startup company based of Virginia, USA.
