Admittedly, I am a little behind the curve on this one. I believe the Locavore application hit the iTunes store in March or so. As the maven of both technology and food, I'm embarrassed that I didn't get wind of it until recently. I'm certain that many of you are in the same boat, so I'm posting it now anyway. As I ranted about with the Local Food Wheel, the Locavor app gives you a rundown of what is in season for any given location. There is a clock icon that gives you a general idea of when a season ends. They also have a preview of what is about to come into season (Figs are starting to appear!!) Outside of the Bay Area or a few other large cities, the information becomes scant but I assume it is only a matter of time before the Slow Food mentality reaches the heartland. (I'm waiting for your complaint "blintz69" that the LA offerings fall short).
Moreover, Locavore also has Farmer's Market listings (proximity to you generated by the GPS) so you can easily find one close to you. I'd like to see them add searchable schedules, rather than just pull up the LocalHarvest web page. It would help to be able to look at a calendar and know where the closet market is on any given day.
There is also a community section where you can share feedback on produce in a 150 mile radius, 500 mile radius or The World. I'm not sure what we're supposed to get out of it, but everyone is about social networking these days.
I think they've done an excellent job on the application and can't wait to see future releases. It's well worth the $4. You can click here or click on any of the images for the iTunes link to the application.
