>Have you ever recorded a whole-day track with it?
The most my partner's recorded is six hours on her iPhone. By turning of
the display when it's not needed, we estimated that battery life would
be about ten hours.
>Have you ever
>successfully recorded a track with a GPS interruption, like
>driving through a tunnel?
Haven't tried that but we've only been using it for about eight weeks
and haven't encountered any tunnels in that time. As it uses the iPhone
GPS, any problem would not be unique to ViewRanger. In a situation where
her Garmin Vista was suffering from persistent multipath, the
iPhone/ViewRanger track was rock steady. Tree cover is also handled
without a problem.
>What makes you think that it is more
>reliable than the other track recording programs?
I haven't tried any of the others, so can't answer that.
>Does it create files in any standardized format?
Track files can be converted into GPX format which we've successfully
imported into Garmin Base Camp and into Memory Map. This requires the
use of iTunes as a transfer medium. How Android and Symbian systems
handle this is no doubt covered in their respective manuals available, I
think, on the ViewRanger site.
