There are literally hundreds of thousands of iPhone, iPad and Android apps to choose from, and yet finding good apps is far from easy. App discovery and recommendations is a fertile niche where a few startups are fighting for mindshare. After being downloaded more than 2 million times, app discovery startup Appsfire closed a $3.6 million series A, led by French VC firm IDinvest. (Appsfire is based in Paris and Tel Aviv, and was co-founded by Ouriel Ohayon, who used to be the editor of TechCrunch France ). Appsfire crossed 1 million downloads in February, and then the 2-million mark in May. Ohayon says its various apps for the iPhone , Android, iPad, and kid's apps is generating 3 million leads to app developers each month. Appsfire lets you share your favorite apps with your friends via the web, your mobile device, or Facebook .
