Like to leave your impressions of places you've been to for the world to hear? Then you'll love Voice Mark, which lets you create geotagged audio recordings of any spot on the map, as well as listen to those made by others.
GeoGraffiti calls each recording a "voice mark," which is essentially a short phone message that's geotagged to a specific location and piled away into the system's database. You can either create the recording and send it over your data connection, or you can ask GeoGraffiti to call you so you can leave a voice mail. The latter, by the way, is a considerably faster option.
Now, say you're a user who's driving in an unfamiliar part of the city and you spot a diner that looks good. Is it a good idea to eat there? You can get help by launching the app, finding the establishment and listening to the voice marks left by others.
The software uses the Google Maps interface to locate the areas you're interested in. You can toggle the view to show the previous audio geotags from other users scattered throughout the map. Simply tap the placeholder and listen to the message. The UI is very intuitive, making the process of getting your prerecorded reviews an uncomplicated matter.
Like all reviews-based apps, this thing will only take off if users actually take the time to leave their own voice marks. I'm lazy about these things, but I'm guessing there's a whole plethora of people who will. I'd be more optimistic if the "reviewers" actually had some kind of incentive to post their audio recordings, though.
Voice Marks is available free from the App Store.
