HOW SURE ARE WE
Not in any grossing chart, so this comes from ratings growth (0.2 new ratings a month on average since launch): revenue grows with new ratings, more slowly for apps that collect ratings fast. Tested on 418 apps with verified revenue: typically off by about 2 times, and big earners tend to come out low. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

Useful, it helps15%

2 of the 4 and 5 star reviews.

★★★★★ I really just wanted a simple tool for dialing in various chords to see what dominant, augmented and diminished versions of each looked like. It does all of this and I think is worth the .99 I spent on it.
★★★★★ Useful app, does exactly what it says, even sounds out the chords and scales!
