Problems...... – Music Tool LE Review

I like the idea, but there are a couple of issues. Of the selections for key changes, two don't work. You can't access D, and G. I also can't access the 'Circle of Fifths'. The only other issue; there is no way to contact the developers from within the app. Why would I spend $4 for the full app when there are such essential parts of the LE version that don't work, and there are no way to address the issues? If they fix those issues, I will adjust my rating accordingly, and purchase the full version. Update: I found out how to contact the Developer, and he was Great!!! He got back to me immediately, and suggested a couple of possible remedies. I will definitely purchase the full version.
