Coming soon to iOS
Sleep guidance you can cite.
Solas reads the peer-reviewed sleep literature so you don't have to — then turns it into one specific thing to try tonight, tuned to your trimester, your postpartum stage, and your wearable.
Why Solas
-
Built for perinatal sleep
Pregnancy and postpartum sleep don't behave like adult sleep. Solas's library is filtered to studies that recruited pregnant or postpartum participants — or that ask a question that demonstrably generalizes to them.
-
Wearable-aware, not wearable-required
Connect Oura, Apple Health, or Whoop for objective metrics — or use the manual check-in. Every recommendation explains which signal it's reacting to and why.
-
One nudge, not a dashboard
Each night you get one specific intervention to try, with the citation behind it. No streaks, no shame. Just a small, testable change.
-
Bedroom-environment scoring
Use the camera and microphone to measure ambient light and noise on the spot. The thresholds come from the literature — 100 lux harms cardiometabolic function (Mason 2022), HEPA air added 12 min of sleep (Lamport 2023).

Frequently asked
Is Solas a medical device or a diagnostic tool?
No. Solas is a behavioral coaching tool that summarizes published sleep research and translates it into nightly suggestions. It does not diagnose or treat sleep disorders. If you suspect obstructive sleep apnea, severe insomnia, or postpartum depression, see a clinician — Solas will point you to screening criteria from peer-reviewed guidelines (e.g., Dominguez 2023 SASM/SOAP).
How does Solas decide which research is trustworthy?
Every recommendation is backed by a paper that lives in our public research library at /research. Each entry shows the authors, year, journal, DOI, and the specific finding the recommendation depends on. We prefer randomized controlled trials, network meta-analyses, and consensus guidelines, and we flag entries whose details we have not yet independently verified.
Do I need a wearable to use Solas?
No. The manual check-in captures the inputs that matter most for the recommendations. A wearable (Oura, Apple Health, Whoop) lets Solas reason about objective signals — sleep latency, awakenings, heart-rate variability, readiness — and surface the specific signal a given recommendation is responding to.
What stages of the perinatal journey does Solas support?
Each trimester of pregnancy and the first 12 months postpartum, with stage-specific filters on the research library. A study about HEPA air filtration in healthy adults shows up; a CPAP-titration paper in non-pregnant cohorts does not, unless a perinatal guideline cites it.
Is Solas free?
There will be a free tier with the nightly recommendation and full access to the research library. A subscription unlocks deeper personalization, longitudinal trends, and partner sleep tracking. Final pricing will be confirmed at launch.
What about my data?
Health data stays on-device when possible and is encrypted in transit otherwise. Wearable connections use OAuth; you can revoke any source from Settings. We never sell health data, and the waitlist email you submit here is used only to email you when Solas is live.
