Our Review:
TripTik is AAA's entry into the navigation / GPS app market.
In terms of routing it's pretty straight forward. You enter your starting point (which can be either your current location or an address) and an ending point. TripTik then find the path to your destination. Generating your path is accurate and fast.
As you start your trip, the complete directions are announced. While traveling along the path, your current location, as you'd expect, is updated. When it comes time to turn, however, TripTik doesn't announce that a turn is approaching. Likewise, after you make the turn, TripTik doesn't announce the distance until the next turn. To make it announce the rest of the trip you must push the copilot button or shake the phone.
While testing the app, there were several times when my location would suddenly move to a different road only to return to the correct location in the next second. I think this may have been due to poor GPS accuracy in the phone, but it may prove to be an issue if you are in an unfamiliar area.

Besides not having turn by turn announcements, TripTik is missing other features found in most stand alone GPS devices. Things like detour mapping, or choosing if you want to use highways, non-highways, or both.
Exploring the maps works as you'd expect--swiping, pinching, etc are app supported and update quickly.
TripTik has quite a large database of points of interest--gas stations, restaurants, hotels, etc. Which could be very handy especially if you are in an unfamiliar place.
For free, TripTik is good replacement for the maps app built into the phone, but it's lacking many features built into my old GPS, so i think i'll keep that one around a bit longer.
