Dopplr Launches iPhone App, But Where’s The Add Trip Button?

Dopplr has launched an iPhone app they are billing as a "social atlas". Curiously, and possibly wisely, you don’t even need an account at Dopplr to use the app, meaning it will get exposed to a lot more potential users. However, a let down from the get-go is that you can't add upcoming trips from within the app right now, which is kinda the point with Dopplr, as it's users will attest - although the feature is planned, they say. The app appears first on the iPhone, but apps for Nokia, Blackberry and Google Android platforms are also in the pipeline. The app is available from the iTunes store here . There is plenty of content inside the app pulled from Dopplr's own content as well as your social network. The question mark with Dopplr is how it will continue to fair against Tripit, which is tearing along at a fast pace and recently launched premium flight monitoring and alerts.
