"Agree on the Andriod version - not sure why they want to go down the Apple road..."
Developers sometimes say that it is faster and easier to develop the iOS app. Probably depends on the developer .
In any case, Lionel planned to have the Android LionChief/Bluetooth app available simultaneously with the iOS, but development has taken
longer, according to Ryan Kunkle (source: Notch 6 catalog podcast). You'll have your Android app sooner or later I'd guess.
Used my cab-1 and a Legacy loco and my LionChief universal remote and two LC+ locos together today. Works seamlessly and well.
Apparently the Bluetooth app has a number of features not available using the LC or LC+ remotes (individual control of sound volumes for one thing). So the Bluetooth locos will have some nice features more easily provided with a phone or tablet device than with a remote, at least for the present. The newer remotes (including the universal) with Bluetooth are firmware upgradable apparently.
