Why Solas

Most sleep advice wasn't written for you.

"Get eight uninterrupted hours" is useless to a body that's biologically rewired for months — and to a mom who's up at 3am. Solas works with the sleep you actually get, and earns your trust by showing its sources.

One nudge a night

One small thing to try tonight.

No dashboards, no homework. Each night Solas gives you a single, specific, science-backed step — tuned to your stage and how you actually slept. Tap the citation to read the study yourself.

A guided plan

A plan that meets you where you are.

A gentle, night-by-night program builds better sleep habits across the pillars that matter most — regularity, satisfaction, alertness — adapting as your body and your baby change.

The Clearing

A quiet place for what's on your mind.

The thoughts that keep you up don't belong in a social feed. The Clearing is a private, calm space to set them down — so your mind can rest, too.

The Clearing — a private journal
Newborn sleep

A plan for your baby, too.

Answer a few questions and get a personalized newborn sleep strategy grounded in safe-sleep guidance — so the whole house rests easier, not just you.

45

peer-reviewed studies behind the guidance — each recommendation cited, so you never have to take our word for it.

Advice you can actually trust

Real science, not hot takes.

Solas reads the peer-reviewed sleep literature so you don't have to — then turns it into one calm, doable step. Every claim traces to a primary source:

OSA & altered glycemic patterns in pregnancy
Farabi SS et al. · J Clin Endocrinol Metab, 2019
Evening light, deep/REM sleep & next-day insulin sensitivity
Mason et al. · PNAS, 2022

Questions

The honest answers.

Is Solas a medical device?

No. Solas is a behavioral wellness companion that summarizes published sleep research into nightly suggestions. It doesn't diagnose or treat — and it points you to a clinician for red-flag symptoms like possible sleep apnea or postpartum depression.

Do I need a wearable?

Not at all. A 20-second manual check-in captures what matters most. If you have Oura, Apple Health or Whoop, Solas can reason over objective signals too.

How do you decide what's trustworthy?

Every recommendation is backed by a peer-reviewed paper in our public research library — authors, year, journal, and the specific finding it depends on. We prefer randomized trials, meta-analyses, and clinical guidelines.

What stages do you support?

Each trimester of pregnancy and the first 12 months postpartum, with stage-specific guidance that changes as you do — plus a personalized newborn sleep plan.

What about my data?

Health data stays on-device where possible and encrypted in transit otherwise. Wearable connections use OAuth and can be revoked anytime. We never sell health data.
