Track how your body adapts at altitude and keep your team on the same page. Log SpO₂, heart rate, overall wellbeing, sleep quality, and specific symptoms—including headache, nausea, shortness of breath, insomnia, sleep apnea, and swelling. Add your current camp altitude in meters or feet and see how changes correlate with how you feel.
The Today screen makes evening and morning check-ins fast: tap to edit, slide to select, save, done. A built-in calendar lets you jump to any night to fill gaps after a long day on the trail. Clear charts highlight 3, 7, or 14-day trends for oxygen saturation, mood, and symptom intensity so you can spot plateaus early and pace your ascent.
Helpful reminders nudge you for hydration, symptom checks, and morning load checks. “Soft hints” give subtle warnings when your numbers drift the wrong way without alarming you. Everything is designed for quick use in a tent or hut: large targets, low-light friendly colors, and no clutter.
Use it for weekend hikes, multi-day treks, ski tours, and expedition camps. Whether you’re acclimatizing, monitoring a partner, or simply curious about sleep and recovery above sea level, this tool helps you make safer decisions: ascend, hold, or go down. Your data stays on device; you control what you log and when.
