What!?! – Piano Melody - Play by Ear Review

I would give this app a higher rating but while I was doing the higher lower at told me I was wrong twice. Error msg was the second C5 is higher than the first C5. How can that be!?!!!? C5 is C5....hello it is the same. So, do I press the up and the down arrows together so that the game recognizes that the two tones are the same? Or am I going to be wrong no matter if I was the up or down arrows for the same tone. Grrrr, so flustered.
