how many apps are on the google play store
Google Play As of February 2017[update], Google Play features over 2.7 million Android applications.[1] Users in over 145 countries can purchase apps, although Google notes on its support pages that "Paid content may not be available in some provinces or territories, even if the governing country is listed above."[2] Developers in over 150 locations can distribute apps on Google Play, though not every location supports merchant registration.[3] To distribute apps, developers have to pay a one-time $25 registration fee for a Google Play Developer Console account.[4] App developers can control which countries an app is distributed to, as well as the pricing for the app and in-app purchases in each country.[5][6] Developers receive 70% of the application price, while the remaining 30% goes to the distribution partner and operating fees.[7] Developers can set up sales, with the original price striked out and a banner underneath informing users when the sale ends.[8][9][10] Google Play allows developers to release early versions of apps to a select group of users, as alpha or beta tests.[11] Developers can also release apps through staged rollouts, in which "your update reaches only a percentage of your users, which you can increase over time."[12] Users can pre-order select apps (as well as movies, music, books, and games) to have the items delivered as soon as they are available.[13] Some network carriers offer billing for Google Play purchases, allowing users to opt for charges in the monthly phone bill rather than on credit cards.[14] Users can request refunds within 48 hours after a purchase if "something you bought isn't working, isn't what you expected, was bought by accident, or you changed your mind about the purchase".[15] Apps meeting specific usability requirements can qualify as an Android Wear app.[16]
