There are more than 25 alternatives to RocketAPK, not only websites but also apps for a variety of platforms, including Android, Android Tablet, Windows and Kindle Fire. The best alternative is F-Droid, which is both free and Open Source. Other great sites and apps similar to RocketAPK are Aurora Store (Free, Open Source), Google Play Store (Free), Aptoide (Free, Open Source) and APKPure (Free).
Aurora Store is an unofficial, FOSS client to Google's Play Store with an elegant design. Not only does Aurora Store download, update, and search for apps like the Play Store, it also empowers the user with new features.
Aptoide is a distributed marketplace for mobile applications which runs on the Android operating system. In Aptoide, unlike the default Google Play Store, there is not a unique and centralized store but each user manages their own store.
The project's aim is to promote free and open source software on the Android platform. Fossdroid takes its data from F-Droid, but organizes apps in an attractive, Google Play-like arrangement with the ability to view apps by popularity.
In an effort to make things easy, and maybe even fun, AndroidPolice.com created APK Mirror. Over the past several months, they've been working to build a smooth, reliable, trust-worthy site to host the downloads users love. You also can upload APKs to the site yourself.
