Hi Folks: For those who are looking for real time traveling accuracy, I offer this observation. Using the app on an iPhone 4, I found that: 1. Whether the monitor was turned on or off, the app continually updated the direction heading and even that, in many cases was incorrect. 2. In some cases, the cross street was named when I was 10 or 20 pases on the other side; great if you want to know where you were and not where you are going. 3. In many cases, the cross streets were not named at all. In summary: the app may be worth the money if you want to invest in the creator's R&D costs of developing an orientational GPS app for the iPhone; but if you are looking to depend on this app, you might want to wait a while -- the app is simply not ready for PrimeTime. Maybe Mike or someone from Sindero might want to waigh in on this subject. Cheers.
