Not impressed so far It has a heads up mode. However, zeroing the pitch for the attitude display does not seem to work when it is used lying flat. Annoyingly the units do not include knots/ nautical miles. A PDF manual would be useful. I know the gyros and accelerometers in mobiles are not that high quality. In principle however it should be possible to get a crude INS to work and hopefully future phones will have better sensor platforms.
InertialNav Nice application with good UI. There is a lot of work in the covariance settings and Kalman filters. I was quite disappointed that the text output does not seem to work, and this was the main reason I bought the app. Toggling between GPX and MatLab seems to always give GPX output. I sent a email reporting the bug last week, but so far have had no response.
Title Not sure it is doing what it says. I expected to be able to use it a a nav tool while the GPS is disabled (after getting a position) but the ground track is also turned off. If I leave the GPS turned on and it loses the signal will it still calculate position via other sensors??? Lack of ability to zoom in and out on google map view is very disappointing. Using S4 Galaxy

Almost The calibrate sensors option seems to do nothing. It has option to zero pitch but no option to zero roll. If I could zero roll I'd give it four stars, the sensor filters are the best I've seen in similar apps but having the horizon perpetually crooked makes it unusable.
Export track data to GPX file.
Upgrade compass with camera view.
Improve fragments management.
Minor bug fixes.
Thanks for reporting bugs. If you find an issue, just send me an email, I'll correct it promptly.
