Android app to change pitch of recording?

Hi -

Any recommendations please for a good Android app that allows me to play a song back at the same speed but different pitch?

I’d like to practice a harmony that’s not on the record, but our band is playing it two half steps lower than recorded. An app like that would free me from having to be near my keyboard to practice. Good for me, provably not as good for those in my vicinity! :lol:

Thank you for any suggestions! :blush:
