Have you checked out the Unofficial Symbaroum app yet? Available now in a completely new version that looks great!
(The link is for the Android version. There is an iOS version too in the App Store.)
Good to hear! I just gave the developer's address to someone who wanted to contribute to a Spanish version, so it's getting better and better. Wonder if there's any chance of it becoming an official app?Yeah ! Very good app ! French version is in progress
