It cleverly integrates maps, a web browser, and a tracking mode to show new points of interest as you move. You can share destinations that you find with email, SMS and the clipboard.
You can also search any one of 600 categories or ask the app to surprise you with, for example, a restaurant recommendation.
The app supports English, Dutch, French, German, Greek, Italian, Spanish and Portuguese.
How did it work? Pretty well. It's nice to have all the tools you need in one app, although one of my favorite apps, AroundMe [iTunes link] integrates maps, but has no browser. AroundMe is free.
It would be nice to get some integration into the new nav apps that are proliferating, because Where To? has a far larger POI database then say Navigon or TomTom. I did save a POI from Where To? in my contacts, then opened that contact in Navigon and that worked fine, but it's a little fiddly.
There are a few glitches in Where To? While searching for some nearby lakes, the app found some businesses with "lake" in the name. I think the app is focusing too much on the business name, and not whatever category meta-data it is using.
All in all, this app was worth the original $3.00 asking price, and today at $0.99 I'd give it a whirl for sure.
Here are some screen grabs:
