A walking router that minimises the heat your body absorbs

Two spots in Phoenix can report the same air temperature while one hits your body with nearly 25°F more heat off the asphalt. MrNetwork built Cryonav solo in eleven days to route walks by absorbed heat, with an Emergency Sentinel that alerts a contact if you stop moving in extreme heat.

I don't often ask my network for things. I'm asking now.🙏

I built Cryonav solo in eleven days, and it's now in public voting for the FortyGuard Global AI Hackathon '26. One minute of your time would mean a lot.

Why it exists:

Two spots in Phoenix right now are reporting the exact same air temperature. Zero difference. Walk between them and your body absorbs nearly 25°F more heat at one than the other.

Every weather API and every navigation app is blind to that, because they measure the air. What hurts you is the heat coming off the asphalt.

So Cryonav routes you by the heat your body absorbs, not the distance you walk. And if you stop moving in extreme heat, an Emergency Sentinel alerts your nominated contact with your position and the nearest place to cool down.

Built for people who can't choose when they go outside.
