Super Fretboard Flash Cards

Doesn’t work and I bought all the apps had to reinstall and restore purchases doesn’t work Options menu does nothing

Downloaded only to find out I had to BUY NOTATION (for an additional $.99)! Guys, seriously??? Your app is pointless without the staff. Either include it for free or just charge the freaking $.99 in the first place. I was looking for a flash card-like version of Guitar Scorist which (for FREE) lets you play notes on the fretboard AND shows you where that note is on the staff (it also sounds like a real plucked string too). Fretboard Flash Card Addict, your marketing method is anything but "super".😑

I got what I wanted from another app. This one sells you enhancements to where you invest $20 plus dollars for the real deal. P.T. Barnum would be proud. Wish I could get my money back.
