Since you never know what you could be downloading, other people's comments tell you whether or not to trust app you're about to download. However, the most important thing to look at before downloading, is the comment and rating section of each app.
Each app's page includes technical information and a description written by the user that shared it. To find a specific app, you just have to write the name in the search bar, and choose the version that you want to download. This market includes tons of free apps available to download. To start using Aptoide you first need to understand how it works. The interface is really intuitive, and is divided into the following tabs: Home, Top, Stores, Updates, Social Timeline, and Download Manager. This means users share games and apps that other markets don't have, or that only offer as paid apps. Aptoide is a market for downloading Android apps that doesn't require any registration, and allows users to create their own 'stores' to share with everyone.
