This is just a web site that allows users to search for apps, with downloads linked from their source page. I wouldn't consider it an app store like what Zapstore is since you can't update apps from it and any other features an app store would have. I'd suggest it only as an alternate option where app stores cannot get the app they want while ignoring the hassle of adding to Obtainium manually. Users should use an app store application as their first choice where possible.
