Andrea Micarelli and I have realized a search engine to find repository aptoide for android. Repo-Finder is very simple to use: you have to specify the name of app that you are looking for and it give you a list of repositories that contain this app. We have realized a desktop version, a mobile version, an app for android and a widget for blogger if they want to made search direcly from their blog from sidebar. Here you can find more information, screenshot and video about Repofinder: Repo-Finder You can use Repo-Finder also to search repository for Cydia (Iphone), repository APT for Ubuntu, and for Linux Mint (soon Debian). If you want to change distribution click on "change distribution" , made your choise and then search your app, package or program. If you want you can give me a feedback so i can improve repo-finder. If you want you can collaborate with this project.
