gpsPrime FAQ


Q: Why does the compass not indicate the direction I am facing?
A: On iPhone 3G devices gpsPrime does 100% of its calculations based on consecutive GPS coordinate readings. As soon as we get an iPhone 3Gs, we will release a version that supports the magnetic compass hardware. With the exception of the pure Longitude, Latitude, and Altitude, all other displays, especially the compass, require the unit to be in motion, and outside. Standing still, you will not see the compass move no matter how much you rotate the iPhone itself.

Q: Why do I not see anything in the data fields when I launch the app?
A: gpsPrime requires a decent GPS signal lock, with consecutive data. Displaying anything earlier would be misleading.

Q: I'm walking around my office, but gpsPrime isn't showing me any love.
A: gpsPrime requires a 'real' GPS signal lock. Apple did a great job approximating it with WiFi and Cell Tower magic, but it doesn't have the granularity for what gpsPrime is doing. Go outside in the fresh air and use it.

Q: Why do I see a progress spinner when I launch?
A: gpsPrime is acquiring the GPS signal from the iPhone. The same spinner occurs during the use of the built-in map.

Q: Why do I see a progress spinner after I have been using the app for a while?
A: gpsPrime has lost the GPS signal from the iPhone possibly due to obstruction of the sky.

Q: What does moving average mean?
A: gpsPrime's moving average takes a 30 sample slice, and averages those values. This is different than a plain average that is only reset via the reset button in the preference panel.

Q: Why does my speed not match my vehicles speedometer?
A: gpsPrime's distance calculations, and therefore speed calculations are based purely on longitude and latitude position changes. It does not take into account inclination and declination, and may be 'clipped' if traveling non linearly.

Q: How do I reset the odometer, trip timer or min/max/avg data fields?
A: via the 'Reset Trip' button mentioned above in the "30 second manual".
