*[Aptoide](http://www.aptoide.com/)* is like a package manager for Android. It retrieves lists of programs from different repositories and lets you install, update or uninstall these programs.

*<http://aptoide.com/repo>
*<http://aptoide.com/sapo>
*<http://android.akuz.de/repo>
*<http://android-es.com/repo/apk>
*<del>http://blapk.com/market/apps</del> (offline, now members-only on [www.blapkmarket.com](http://www.blapkmarket.com/))
*<http://repo.blackdroid.net>
*<http://server.uncabron.es/repo>
