APKGATOR is described as 'alternative Android Market to download free Android apps. All apps on this website are downloadable to any Android smartphone or tablet as apk file' and is an app in the Online Services category. There are more than 25 alternatives to APKGATOR for a variety of platforms, including Online / Web-based, Android, Android Tablet, Windows and Google Chrome. The best alternative is F-Droid, which is both free and Open Source. Other great apps like APKGATOR are Google Play Store (Free), Aptoide (Free, Open Source), APKPure (Free) and APKMirror (Free).
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.
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.
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.
