Helios - Solar Weather Health
Solar Health Analysis
Free · Designed for iPad. Not verified for macOS.
Could solar storms be disrupting your sleep and mood? Real NASA data, analyzed daily. Connect Apple Watch to explore HRV and sleep trends alongside space weather.
The sun affects your health more than you think
Helios tracks real NASA and NOAA solar weather data daily and surfaces potential connections to your sleep quality, heart rate variability, and mood — so you can understand what's happening in your body in the context of what's happening in space.
Five solar moods, updated every day
Helios maps complex space weather into five levels — Calm, Unsettled, Active, Stormy, and Extreme — based on the Kp index, solar flares, and geomagnetic storm data. Each level comes with a full health analysis and practical wellness advice.
Your body vs. the sun
Connect Apple Watch and the Health tab overlays your HRV, resting heart rate, and sleep data alongside solar metrics over 7, 30, or 90 days. No statistical claims — just the data, side by side, so you can spot patterns yourself.
Three-day forecast
See the Kp index outlook, solar wind speed, and interplanetary magnetic field trends before they arrive. Know a stormy day is coming before you feel it.
Built on authoritative data
- NASA DONKI: solar flares, coronal mass ejections, geomagnetic storms, energetic particle events
- NOAA SWPC: real-time Kp index, 3-day forecast, 7-day solar wind and magnetic field
Privacy first
