Sleep Disruption Analyzer

An app that helps users identify what's causing them to wake up at night by correlating sleep data with environmental factors and habits. Sleep-deprived people want a simple way to diagnose their sleep problems without expensive sleep studies.

Wearable adoption has crossed a threshold where tens of millions of people already have sleep-stage data sitting unused on their wrists, creating real demand for a layer that actually interprets it — Oura and Whoop generate the data but neither does root-cause correlation in a meaningful way, making them substitutes only in the loosest sense. The $1k–5k/mo revenue band is honest for a solo founder: a small subscriber base at $8–12/month gets you there, but the ceiling is low unless there's a clear upsell into coaching or a B2B angle with employers or insurers. The biggest risk is data access — Apple Health and Google Fit APIs are permissive today, but building on Oura or Whoop data specifically means depending on partners who have every incentive to absorb this feature themselves, and one API policy change breaks the core loop.
