Stardust
Build your pre-flight baseline. Catch in-flight drift before you feel it.
Stardust is a personal health monitor built for astronauts in training and in orbit — and for anyone who wants to track their body the way a flight surgeon would. Log vitals, labs, sleep, and cognition on your phone; Stardust pins your pre-flight baseline, then flags when your in-flight numbers drift past it. The four Inspiration 4 crew members are layered in as cohort context — the only published in-flight comparison group there is. n=4, treated honestly.
What spaceflight does to the body — example
White blood cell count across the four crew members through the flight. The cohort's WBC was higher 3 days before launch (L-3) than at any point during or after it. This is exactly the kind of shift Stardust watches for in your own data — pin a pre-flight baseline, then flag when in-flight values pull away from it. Suggestive at n=4, not significant.
Pre-flight baseline
Flip into pre-flight mode and Stardust pins your personal median across every metric. Every chart gets a dashed baseline line so you know what “your normal” actually was.
In-flight drift detection
Flip to in-flight mode and Stardust watches vitals, body, wellness, and visual biometrics for directional drift past your baseline — with severity tiers, not alarms.
Lab report scanning
Snap a photo of a CBC or CMP and Stardust extracts the values on-device, plots them against clinical ranges, and adds them to your trend. PDF, DOCX, and CSV imports too.
Wearables + Apple Health
Sync heart rate, sleep, HRV, VO₂ max, and steps from your watch. Manual logs and wearable data live in the same chart.
Cognitive battery
NASA-aligned PVT, Stroop, DSST, N-back, and Memory Search, scored against your own pre-flight baseline. Cognitive drift gets the same treatment as vitals.
AI coach
Streaming Claude explanations grounded in your recent readings and the I4 cohort context — not generic health advice, not a diagnosis.
