HOW SURE ARE WE
Not in any grossing chart, so this comes from ratings growth (1.2 new ratings a month on average since launch): about $100 a month per new rating a month. 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.

Latest reviews, United Kingdom App Store.

★★★★★Nov 13, 2024
No exercises

I thought there would be exercises like the online version but there isn’t. Quite disappointed

★★★★★Jul 15, 2021
Bare bones

The app has a very little amount of audible examples, especially in the meters and time signatures chapters where it's very crucial to heat the difference between complex time signatures. There are literally no exercises in the app to help you progress. The theory text is very repetitive and uses very subjective terminology with no attempts to explain it. For example, what does it mean that a seventh note in a minor scale "wants to lead"? No explanation for that, they just go forward with this.

★★★★★Jan 3, 2021
A ‘Go-Too’ app....

As a music professional I heartily recommend this app. Clear, precise, brief. Absolute simplicity to use. A design triumph in my view fellas....

★★★★★Jan 10, 2019
Classic

A beautifully presented summary of music theory, presented cleanly, accurately and quietly: Great value.

★★★★★Sep 12, 2017
More of a summary than actual lessons

I've given it four stars because it does give a lot of useful and concise information, but it doesn't really explain some things at all. - the "key signature calculation" lesson makes little sense to this "theory novice" for example. However it's very useful to help you understand what you've learned elsewhere. I wouldn't recommend using this app in isolation. But I would recommend using it as an extra resource.

★★★★★May 23, 2016
Limited content

Not much there, but has potential. No narration, limited sounds. Could be combined with their other app. Time will tell
