The report published by Analysis Group claims that Apple's own apps are infrequently the dominant option and only account for a small share of app usage. Apparently Apple software is so bad that App store competitors are laughing all the way to the bank. 

"We found that Apple's own apps, while used by many, are rarely the most popular of a given type and are eclipsed in popularity by third-party apps for nearly every country and app type we considered," the report said.
In the US, the report found that Spotify was 1.6 times more popular than Apple Music, that Google Maps is used 1.5 times more than Apple Maps, and that Netflix is 17 times more popular than Apple's service. The Amazon Kindle service, meanwhile, was 4.5 times more popular than Apple's Books app.

The report is funny because it shows that Apple is prepared to throw its own apps under the bus if it will get it out of anti-trust hot water. The Tame Apple Press says it must be true because it is written by actual economists. However, at no point does anyone wonder why is Apple distributing the report from its own website? 

If they read the cover, Analysis Group said that while the conclusions and opinions expressed are exclusively those of the authors the report was compiled with Apple’s support.
