Unfortunately, there is no Android version of Maven yet. A search of mavenpilots.com found this:
A:Currently the Android version is not available, we assure you that we want an Android version more than anyone else but unfortunately there is no shortcut to bring an app from iOS to Android, every little part has to be totally rewritten and tested. To date, unfortunately, we still don’t have an expected date.
It sounds interesting and I'd like to try it but don't have access to any iOS devices.
It's understandable, though. Michelle (the author of Maven) is a solo programmer and has spent a long time writing the iOS version. He says he still has other ideas for the iOS version, so he can only do so much.
