Stop Guessing.
Hike Warm. Sleep Warm.
Your past outings hold the answer. Thermal Buddy turns your hiking and camping logs into a personal comfort database — so you know exactly what to wear and carry before you ever leave the trailhead.
Imagine Waking Up Warm Every Time
That’s not luck — it’s data. Thermal Buddy builds your personal comfort profile from real outings, so you stop packing by instinct and start packing by evidence.
- ENJOY: Know before you go. Pull up your logs and see exactly what worked in the same conditions — temperature, weather, terrain. No more second-guessing your sleep system at 2am.
- REFINE: Each outing sharpens your profile. Your data tells you what layer to keep, what to cut, and what to swap.
- RECORD: After each outing, log your layers, the conditions, and how you felt. Hot, cold, or Just Right. Takes 60 seconds.
Why Thermal Buddy?
- Built for Hikers. By a Hiker. Eiji built this app after too many cold, sleepless nights under a tarp. It solves the layering and gear guessing game for good.
- Your ‘Just Right’ is Unique. Move beyond generic recommendations. Rely on your own comfort data — there’s no one-size-fits-all when it comes to thermal comfort.
