See how your environments shape your sleep and focus.
Eatha pairs atmospheric conditions in your rooms with Apple Health data to show which conditions best support your focus, sleep, and recovery.
What Eatha does
Your room is part of the equation.
You track your sleep. Your strain. Your steps. But the air you breathe for 6–8 hours a night often goes unmeasured. Eatha tracks CO2, temperature, and humidity - and lets you see how those variables move alongside your sleep and daytime performance. It doesn't guess. It shows you the data.
CO2
690 ppm
Ideal <800 ppm
Clearer focus. More consistent sleep. Fewer mystery slumps.
Your air shifts your cognition before you notice.
Subtle CO2 and temperature changes coincide with dips in clarity — Eatha surfaces them.
Make your bedroom measurable.
Overnight air quality, layered with your sleep data. See what changes on good nights.
Catch the slump before it hits.
Afternoon fog often traces back to the room. Act before you hit the wall.
Real-time
See when CO2 starts to climb.
Live CO2, temperature, and humidity readings from the rooms you use most - with simple prompts when it's time to open a window or adjust the airflow.
Better-air environments have been linked with 61% higher cognitive function scores (Allen et al., 2015).
Sleep & Recovery
See how your bedroom conditions affect your sleep.
Overnight environmental readings layered with your Apple Health sleep data. See exactly what your bedroom was doing while you slept - and what was different on your best nights.
Studies have shown a 5-10% drop in sleep efficiency as bedroom temperatures rise above 25 degrees C (Zanobetti et al., 2023).
Patterns
Discover the conditions where you focus and recover best.
Over time, Eatha highlights patterns between your environment, your sleep, and how you feel and perform. Log what you did before bed to add another layer.
Better indoor conditions have also been tied to estimated productivity gains of around $6,500 per person, per year in office settings (Harvard Healthy Buildings).
How It Works
One device. Continuous clarity.
Place Eatha in any room. Compact and unobtrusive (7 cm wide), it fits anywhere without drawing attention. It measures quietly and continuously, then pairs directly with your iPhone to show how your air shapes your health.
Place
Put a small Eatha sensor in your bedroom and workspace. It continuously measures CO2, temperature, and humidity - quietly, in the background. Up to 5 days battery life, rechargeable via USB-C.
Connect
The Eatha app syncs securely over Bluetooth. Your environmental readings are layered alongside your Apple Health data, and you can log what you did before bed - so patterns become visible over time.
Adjust
Open a window. Shift the temperature. Change your pre-bed routine. Keep what works, and build a clearer picture of the conditions that support your best sleep and focus.
