Maestro for iOS and Android (progress update)
Coming soon to an iOS device near you!
For the time being, we have decided to focus on iOS development, so our first iOS app will be Maestro Flash Cards for iOS (universal).
Design is complete and development is on track to reach code complete this Summer 2014.
We will revisit the prospect of an Android version later in the future, but for now we have no immediate plans to work on it until we find an Android developer.
