What key is a track in?

[freewheeling]

I am new to Jamkazam and so I think I might be asking a really stupid or obvious question.   I want to know what key the track is in but I can not see that information.  The app has the option to change the pitch by semitone but it doesn't say what the starting pitch/key it's in.   I want to sync the track with the music notion that I have.

What am I missing?
