TUAW's Daily iPhone App: Traveler's Quest
Traveler's Quest is an oldie but a goodie in the App Store -- it's a GPS-based treasure hunting map that will send you searching around your own area for virtual treasure with a game layer on top of it. It's simple to play and learn, but there's an addictive quality to hunting down and finding a certain location with your iPhone's GPS that will keep you playing while out and about, whether you're wandering around a vacation spot this summer or just exploring your own neighborhood.
The app just got updated to version 3.0 as well, and the new version adds a whole list of interface improvements, along with a "Message in a Bottle" feature (allowing you to leave virtual messages along with any treasure you happen to claim -- kind of like virtual geocaching, and very fun) and some new Game Center achievements to chase after. Great app -- Traveler's Quest is a free download on the App Store, with various features available for an extra in-app purchase price.
