Good but needs updates to become great
Really good music theory app (that teaches the same way a book would, which is rare and nice, most apps just offer practice little exercises only) that could be more popular if they did a few changes: -Modernize the UI look (no need flashy effects but at least a clean material design style with modern fonts) -Remove comments visual pollution -Make it size properly on iPad -Less short subpages, more scroll with markers -Ideally interactive examples like theory lessons app -An option page to customize stuff like background color, etc…
