Aptoide is an online marketplace for mobile applications which runs on the Android and iOS[2] operating systems.

The software package is published by Aptoide S.A., a for-profit company incorporated in 2011, and headquartered in Lisbon, Portugal.

The concept is inspired by the APT packaging manager, which can work with multiple sources (repositories).

The name Aptoide is formed from the words "APT" (the Debian package manager) and "oide" (the last syllable of "Android").

Aptoide started as a proposal of Paulo Trezentos at the 2009 Caixa Mágica Summer Camp.

In 2015, the company secured a Series A financing round of 3.7 million euros (4 million dollars), led by German venture capital firm e.ventures with co-investment from Gobi Partners (China) and Golden Gate Ventures (Singapore).

[13] In 2014, Aptoide filed a European Union Antitrust complaint against Google, claiming that Google creates obstacles for users to install third-party app stores, links essential services with Google Play (thus blocking, again, these third-party app stores), and blocks access to Aptoide websites in its Chrome Web browser.

Launched in conjunction with the 2017 Web Summit edition, the $18 million Initial Coin Offering (ICO) will allow users to use AppCoins to pay each other or for in-app purchases, such as game upgrades.
