Go Game Clock for Android
I appreciate that this has been freely offered and has no ads. It works. Very flexible but also more complicated to configure. Main drawback is lack of audible warnings.
Yes
Why does the settings page take up two screens and why do I have to set the two clocks separately?

I would like to be able to orient the clocks differently, such as opposite directions towards the top and bottom of my phone. But that is a minor issue and not even worth a star. I enjoy the fact that one player can blitz and the other can think with separate time settings; changes the way we give handicaps.
