Since we haven't had enough crashing apps recently, let me add another scenario that causes the Android app to crash:
Phone is connected to a wifi network.
The internet connection of that network is unstable or broken (not the phone wifi connection, but the internet connection of the network itself). This is often the case with free wifi connections on public tranport for example.
Opening the Logos app when such network is active will cause the app to crash immediately after startup. (Not fixed by the recently released update. I already tried it on the bus today.)
