Apps to get your groove on at Lollapalooza
says: Lollapalooza is THIS WEEKEND in the fine city of Chicago - three days of fun and fine music. Navigate your way from show to show and don't miss a thing with the official Lolla app and these others for getting around the Windy City.
Lollapalooza Official App
The official app from the good people at Lolla, it keeps you on track with schedules and maps. Includes a fun group-text feature to keep in touch with friends at the fest, and listen to Lolla radio on Slacker if you can't get where you want to be on time.
Chicago Transit Tracker Lite
Unless you're sleeping in a tent in Grant Park (not that there's anything wrong with that, but it might not be exactly legal), you'll need to get around town. Find the fastest routes and schedules for the CTA buses and trains.
Another transit tracker, but this one has some more social features to help you find good food and drink near whatever transit stop you're at.
