Hello,
I have joined the ranks of folks developing apps to memorize note names on the guitar. Mine is called Frets-101G, and it is available on the google playstore at this link: https://play.google.com/store/apps/details?id=com.nwprojectdevelopment.Frets101G&hl=en . So far I have put a year into the project and I am hoping to get some feedback or suggestions. The main features are ad supported and free, although there is a one-time upgrade for access to additional performance diagnostics and collections of notes for scales and chords. Any comments, critiques or suggestions would be greatly appreciated. Since I am new to all of this, I assume there are flaws - and I won't take it personally if someone points them out. Thanks, and happy fretting!
