Not everyone knows that the Android Market is not the only source for applications. I find very useful and convenient to use aptoide repositories. The working principle is very similar to the debian repositories. There are different clients for aptoide repositories.
For example I use APKtor. But these clients without adding repositories are useless. How do we know which repository to add in order to find the applications that we need? For this reason I have included to the Repo-finder the possibility to search repository for Android. You have only to insert into the search form the name of application that you need and Repo-finder returns the repository that you have to add to your aptoide client.
Soon I intend to add the repositories for Maemo.
So what are you waiting for? Try Repo-finder! There is also a search plugin for Firefox.
