APK downloader - download APK from Google Play Store

How to use： - Open the page of the app you want to download from the Google Play Store, e.g., https://play.google.com/store/apps/details?id=com.google.android.youtube. - Click the APK Downloader extension icon Google browser panel - Click the Download APK button in pop up and the APK will start to download onto your computer. - Now you can install the APK file onto your Android devices. Why this APK downloader? - Unlimited downloads - No ads - No sponsored links - Completely free - APK downloads instantly at your highest speed - Works on multiple operating systems (Windows, Mac OS and Linux) - No need to install additional software Please be careful not to download too many APK’s at once, because Google Play can block you temporarily because of too many downloads (about five minutes). Why APK downloader is helpful: - The App is not available in your country - Get your hands on the latest game, only to find that the Google Play thought it wasn't compatible with your phone - You don't have a snapdragon device, but you're pretty sure an old device could still handle it. Disclaimer: APK downloader is not an official plugin. Google Play™ is a trademark of Google LLC

Doesn't work upon download it will stop and say check internet connection. Tried with both my 2 separate routers with 2 separate isp's and still will not download and saying to check my internet connection. Fix the bug and I will give the extension another try and leave a positive review if working properly until then it will be removing....
