Google play store was initially known as android market. It is a store from which you can download applications. Be it music, movies, games, education related, e-books, tv programs, different kinds of apps can be downloaded for free or for a price. You can say that it is a Pandora box of apps for android users. Over the past few years, several changes have been made in the store, earlier it used to look too chaotic, now it looks more organized.
The layout is easy to navigate on and it is more personalized than it used to be. You can get to see all the apps you downloaded on your device, update them or uninstall. Undermy account you can see all the subscriptions, rewards or order history along with the payment mode, just in case you want to buy an app. compared to windows store and apple store, I like this one more. So many free apps to download. In my phone there are many lifestyle apps, running/workout apps and a few learning apps like duolingo and I didnt have to pay for any of them. Plus the updates are also quite cool, bug fixes, new features.
