It would be nice to have the device location icon show as an arrow (or boat outline) indicating direction of travel instead of a red circle.

I noticed the same issue in portrait mode. Another suggeston would be a bread crumb option. Also when putting in track routes, after the first route is entered and you pinch the screen to zoom in the program shuts down. If you don't zoom in it's ok.

Besides these minor issues, I think it works great!!

Ah! I've never run into that - but I don't know if i've tried that. It sounds like another manifestation of a bug in the mapping kit when it tries to draw a line with only one point in it. I've worked around some similar issues, it sounds like zooming while adding a new route (when it has only one point in it) is another case of that.

Thanks for the report - I will fix ASAP, and am also working on the issue in portrait mode.

bkgoodman, I understand that the iphone has "some" GPS receivers and also uses cell tower aiding information. I have not been able to find any real data as to iphone tested position accuracy and/or data on number of GPS receivers.

We are considering an iphone and the app looks like a good deal for Winni boaters. That is if the iphone position data is consistently accurate enough. We do have a Standard Horizons GPS unit with the Bizer chip in one boat and the combination is very accurate. The iphone app would be used in a 2nd boat but only if the iphone position accuracy approaches the stand alone GPS unit.

Thanks

The whole "cell tower location" (and even "WiFi Station Location") are used only when you have an app that wants to get a vague idea of where you are. An app can request a lower amount of positional accuracy which will use these other techniques. This saves battery life because cell tower location uses less power than running the GPS receiver.

For my app, I crank the accuracy up to "full", which means that you will always be running off of the GPS (as you can tell be the little GPS arrow showing in the toolbar).

As for the accuracy of the iPhone's GPS vs. others - from what I can say from my own experience - it is about as accurate as any other. It does not have WAAS, but unless your doing a precision approach in an airplane, I don't know that that's important.

Aside from that, the only downside I could see on the iPhone vs. another GPS would be the antenna. If you were in some sort of enclosed, shielded cabin, you may be better off with a device that could support an external GPS antenna. (Actually,*can* use an external bluetooth GPS with my app as well. I've tested this and can recommend one that works well. My guess is you really don't need it. [That is more for people with iTouches or iPads with no GPS receivers in them].)

You could obviously experiment yourself with the built-in maps application. My app will have the same accuracy as the phone's GPS when running it.

In summary - I'd say that the accuracy is very good, on-par with any other device and you'll be happy. I have received nothing but very positive feedback from other users, too.
