Reviews and media are sourced from users and Google. The app features 700 categories of destinations, and more than 2,400 brands (e.g. In-N-Out Burger or Trader Joe's). The app features augmented reality as a US$0.99 option, which uses the camera to superimpose directions over local scenery. The app has added direct links to GPS navigation systems Sygic, Waze, Navmii, Navfree and NAVIGON Urban (German App Store only). The app also supports TomTom, Navigon, MotionX and of course, Google Maps.
This latest version has added support for state National Parks in the US, Canada and Australia. The app itself operates in 10 languages, so it's going to be helpful for users around the globe. I did a drive-around test and found it worked reliably and smoothly. I sent a couple of destinations to my Navigon app, and that worked flawlessly. I think the app is useful in your home town, but really comes into its own when traveling and looking for that special restaurant, hotel, or even the nearest pharmacy or hardware store.
Where To? version 4.1 is a free update for anyone who has version 2 or higher. Owners of version 1.0 will have to buy this latest version if they want the upgrade. The app is $2.99 and the augmented reality feature is another $0.99. Where To? 4.1 requires iOS 4.0 or greater. I've included some screen shots of Where To? in action.
