I was “SO INSANELY SKEPTICAL” about this app (And with very good reason!) And I hope more people take time to actually write reviews, because I know darn well, when I want to find out about an app, or (not even on Apple Store, or iPod touch, or iPod, etc...) but everyday consumer products, Years ago, they was a magazine called “CONSUMER REPORTS”, & that’s how everyone made decisions on what they were gonna buy...from Cars, to TV’s, to Blenders, you name it! Lol...But my point is this...I ALWAYS look for reviews, & I happen to see a few for this app, & they were ALL EXCELLENT, so, I said WTH?! And they were 120% CORRECT! I’m VERY, VERY pleased! Just would like to see an addition of different tuning choices added in the Future such as Half Step Down, Drop D, etc...But other than than (which is not a complaint, just a suggestion...this guy’s satisfied! Thank you!
