Aptoide

Aptoide is an online marketplace for mobile applications which runs on the Android and iOS operating systems. Aptoide is also available on smart TVs, STBs, and VR devices. A separate Aptoide Kids app includes kid friendly content. The software package is published by Aptoide S.A., a for-profit company incorporated in 2011, and headquartered in Lisbon, Portugal. Aptoide utilizes a decentralized store model; users can manage their own store. The concept is inspired by the APT packaging manager, which can work with multiple sources (repositories). When the user wants a package, they can use the client to search for sources where the application is stored. The Android application used to access the stores is open source, and there are several forks such as F-Droid. The communication between the client and servers is done using an open protocol based on XML. The name Aptoide is formed from the words "APT" (the Debian package manager) and "oide" (the last syllable of "Android").
