Maybe!

Here's a screen capture of a POC app to record scores.

Click - or + to change the score by 0.5.
Hold the - to record 0
Hold the + to record 10 (you start at 10 and subtract from there...holding will reset)

Click Previous or Next to change the maneuver.

The app will speak the description (with appropriate pauses on those long maneuvers) with amazing sound quality. So with ear buds and both thumbs on the screen, you never have to take your eyes off the airplane. The app also reads the score just entered as you advance to the next. This data will be downloadable to MasterScore via Bluetooth.

So who has a Windows 8 phone?
