By default Google Play will not allow you to download apk files from Play Store on your PC. But thanks to an Android app Developer, Evozi, who has made a one-click online APK download app that will allow you to easily download the APK file of any Android app that’s listed on the Google Play store. You can access the Downloader at apps.evozi.com.
To get started just visit apps.evozi.com and after that there you have to enter the web URL of the app which you want to download from Google Play and click on the “Generated Download Link” button. After that the Downloader will fetch the required APK file from Google Play stores and will give you the download link to download the file.
Note that, this app will only download those apps which are available free of cost on Google Play Store.
