This program can be amazing for mountain hikers, rock climbers, soaring pilots or any other sort of travelers. Indeed, don't you think it could be interesting to know that you climbed higher then the Big Ben or Eiffel Tower?...
NOTE: Measurement relies on your built-in A-GPS, so precision is limited by current level of this technology.
Also, the precision is affected by the satellite signal quality. On open-sky spaces it's pretty good, but under other conditions can noticeably decrease. After startup it requires some time to locate the necessary satellites, so during first minutes of running the measurement can be less effective.
Thanks to everyone for your suggestions about additional functionality, there is a big chance they will be implemented in next release. Please forward your requests to firstname.lastname@example.org email address.
