Just the research and information they’ve put into a nice, organized place with videos and diagrams is worth the $10, which by the way, is the price of a fancy coffee or craft beer. Take the time to study this information and the app will be an incredible tool for all your tuning needs especially for lazy drummers like me. Takes the guessing work out of matching pitches. Thanks to the developer for the years of R&D put into this app!
