First, the good news: technologically speaking, the Aha Mobile traffic app is at the front of the pack. It pairs the iPhone's built-in geolocation capabilities with data from INRIX, Yelp, SitOrSquat, and PhotoEnforced, making Aha your one-stop-shop for data on traffic, food, bathrooms, and speed cameras -- without having to deal with itty-bitty maps. Other features allow you to communicate with nearby drivers and post to Twitter and Facebook. Also, it's totally free.
The bad news? Aha works better in some cities than others, its geolocation tools occasionally go off-track, it's a memory hog, and it's somewhat unstable. But as long as Aha is the one that's crashing and not us, we'll live with it. [AhaMobile]
