What I needed!

Thank you. Seems it’s hard to find a just a simple reference app that you can simply input chords and it tells you the key without any bells and whistles or using the mic to detect. This is that app. Nice and clean interface too. The only reason I’m not giving full 5 stars is because the scroll wheel closes when you lift your finger up which is a bit annoying but the fact it does the thing I need without shoving ads or any crap in my face for free...
