* Google does not publish the number. It might be some 100,000 more. However, the apps missing in App Finder are mostly ones with very few installs and zero or very few ratings. Note that 42matters reports ~3,600,000 apps. Compare with AppBrain and AppAgg (both have ~2,500,000 apps).

** In most larger countries, Google Play shows country-average ratings that are available for only a fraction of the apps for which world-average ratings are available (for example, about 1/3 for the US, 1/7 for the UK, 1/28 for Ireland, and 1/44 for Laos).

App Finder shows world-average ratings for apps without country-average ratings, and has the option to use world-average ratings for filter and sort.

In countries where Google Play shows world-average ratings (e.g. China, Ethiopia, Finland), there is no difference between the ratings on Google Play and on App Finder. See here here for more information.

The paid features are available at just $1 per week / $2 per month / $12 per year / $40 for ever!
