Used this program for the first time today while walking. You can not walk fast enough to make the software lag. The accuracy for me today was within only 4-5 feet, just what I needed to run on my Android Phone. For the amount I had used it, I saw very little battery drain. No doubt that I would be able to use it all day on only one full charge, walking that is. In a vehicle, it would be plugged in anyways. Only thing is, I could use a little more color, but that could still be in the settings.
I'm real happy to have found this program. Now I will probably use it even when I do not really need to. Am looking forward to some of the updates that will be still coming, by then I should have most of the program figured out. And with the ongoing voice there is just no way you could get lost.
Got to like it, for sure.
