I have an "Inreach" - the original brick-like one with replaceable batteries, not the new mini, which I covet but cannot justifiably afford. Similar emergency functionality and tracking to Spot's but higher transmit power + full 2-way messaging (when linked to Earthmate App). No satellite-based system is particularly cheap to run, though; you get what you pay for. I have also encountered one situation (in dense woodland) where my phone worked better! I always carry and use both when "off-piste".
I'm very impressed with ViewRanger for all sorts of things, including "Buddy Beacon", in situations where it will work.
Another tracking phone app I have is APRSDroid, but it's unfortunately only for use by licensed radio amateurs for whom it's free to use. It communicates either through phone data or via a VHF radio, suitably connected to the phone. The radio, though, requires a suitable amateur repeater nearby, just as the phone needs its local mast. Chances are that both or neither method will work in a given place so, like everything else to do with amateur radio, playing with APRS is barely more than a hobby, really!
