>>2454740We do have pipboy-like things tho. You get one of these bad boys with an external temp sensor attached to your hat or pack and you can see barometric changes over time plus you get gps almost anywhere.
Additionally, almost any higher end brand like Garmin will let you make custom apps, meaning almost anything worth doing has been done and if it hasn't, you can make it or ask a nerd from Fiverr to do it for you.
