Download apps directly from Google Play. Raccoon is the only APK Downloader that also supports paid and large apps.
You got an Android device and...
... it doesn't have GApps installed (e.g. custom ROM, Amazon gadget, or chinaware)
... it does have GApps installed, but the Google Play App is too bloated, too nosy, and drains too much battery for your taste.
Then you have come to the right place! Raccoon is a Google Play Desktop client. It allows you to download apps directly from Google Play without you having to give Google control over your phone.
With Raccoon, Google only sees a fake phone downloading apps (yes, even paid ones). The APK files are then archived on your computer from where you can safely sideload them to your real devices.
