Great app in DESPERATE need of a UI overhaul

The app functions as promised, and has long been my favorite guitar tool on any mobile platform, BUT, the UI looks like something off of iOS 5 or earlier. Just looks outdated and could use an update to the current look of iOS 9. If the design was better (UI, icon) would give 5 stars.
