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. Hopefully that feature will be out soon. Till then if you want to add trips on mobile people can use the site, twitter, SMS or email in the usual manner, of course.
The app appears first on the iPhone, but apps for Nokia, Blackberry and Google Android platforms are planned. The app is available from the iTunes store here. But for Dopplr users it’s going to be a real boon. The app puts the combined knowledge of your Dopplr network into an app which can tell your location, while allowing users to upload reviews themselves. There is also a built-in directory of city tips and advice. Plus, as usual, see where your network is about to travel to so you can plan accordingly. Users can also contact eachother directly from inside the app. 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.

I prefer worldmate’s iphone app, worked great on my old blackberry app and has a better UI than either tripit or dopplr.
Have to second that, why no TC love for WorldMate the actual leader in the travel field?
Agree, WorldMate is probably the best travel app around. download and compare: http://www.worldmate.com/iphone

I’m planning a trip to Europe. I have an iPhone and an unlocked Android phone – will probably bring both so I can use local 3g data w/o having to jailbreak my iPhone.
I’ve vaguely heard of TripIt’s email-your-itinerary service, but know nothing about Dopplr or WorldMate. On it’s website, WorldMate seems to be more for business people checking for flight delays.
From the sounds of this article and a quick peek at their site, Dopplr seems more helpful for the inexperienced social traveler.
I’d appreciate knowing why you guys prefer one app to another.
Can you also access Facebook from it?
Agree with comments above. Dopplr is kinda cool, but I think WorldMate is a great tool for a professional travel like me.
if they do a blackberry app then they really will get ahead !
iphone is rather tough to get noticed and while nice to have I would have thought that getting blackberry and iPhone at the same time at least would have been a better bet
