The OP was asking for a Sentinel version that would run in an Android. Uniden has never said there would be any application other than a Windows one to perform the Sentinel duties (update the firmware and database, do some Favorites List programming).
They did (IIRC) say that they were working on an Android version of Siren, this is a totally different animal altogether. I would hope that this is in the pipeline someplace.
At work we get far more requests for a Mac version of Sentinel than an Android version of Siren, but then Sentinel is required for proper operation, the WiFi dongle is more of a toy to try out once or twice, never to be used again for most of us.
