I need to tag a "location" of interest such as
- An nest or hive out in nature where no cellular service is available
- Location of a good view on a mountain (where no cell service is visible)
- Location of a restaurant, bar, other spot that is hard to find.
And I'd like to get relative directions to where that target is (north 500 feet) without having to deal with apple maps, or better still, the ability to plant virtual waymarkers that guide me along the best path using GPS.
Does such a technology exist?
