The software does NOT make use of real-time positioning. It gets your starting location, and then it "guesses" how long it'll take you to move to the next location based on the speed limit. If you miss a turn or get stuck in traffic, it just happily continues on. Apple has blocked use of the A-GPS chip for "navigation purposes" and this app didn't magically find it's way around.
I definitely uses the GPS, it just does not sample frequently enough to detect small changes. For example it may think you're continuing on the highway for a few seconds, when you actually took an early exit. It will correct your position after a bit.
All GPS system use a combination of GPS signal, inertia and "snap to road" to keep your icon on the road in the display.
On the Building GPS systems I have in both my cars, I get the same problem, it's just a little more frequently in G-Maps.

A sat nav app that isn't really sat-nav. FAIL
It is sat-nav, just the maps arent downloaded as they are displayed - they are in a database that lives ON the phone. You silly little man.
A comment proclaiming a failure when there isn't one? Fail!

Sorry, to defend Al here:

according to the ap it says
"Automatic current location update through GPS Tracking"
If that doesn't mean turn by turn w/GPS can someone tell me what that means?
