Since then, Michael went on and started Ringful, a mobile mashup company for voice and mobile messaging applications. Ringful is the creator of apps such as Facebook Voicetag, Instant conference calls on the iPhone, Calendar-based conference calls, and Two-factor ID Verification via mobile phones.
A couple of days ago Michael sent me an email about his new app, the Pollen Journal which is the first pollen forecast app (and corresponding back-end mashup) for the iPhone.

Very cool. Expect more new cool apps coming from Ringful…
