A small apartment living room at Dawn, low warm light entering from the window, long soft shadows across a wood floor. The same living room at midday, bright even daylight, no lamps on. The same living room at Dusk, low coral light through the window, the room dimming.

The natural light score for homes

Light changes all day. A listing photo doesn’t.

DawnScore measures the light a home actually gets, from Dawn to Dusk, and turns it into one number you can trust.

Low and warm across the floor. The hour that decides your mornings.

Noon. The score

One score. Three dimensions.

Every DawnScore is built from three measurements, each tracked from Dawn to Dusk.

Sample score. 85 Pike St, Seattle.

Scores read in plain language.

Three levels of truth

Every score tells you how it was earned.

Start from your couch. Finish at the front door. Photos stay optional at every level; they raise confidence in the score.

Preliminary Free. Instant.

Type an address. DawnScore reads the sun’s path over that exact lot, weighs fifteen years of local sky, and scores it in seconds.

Scan At the property.

Point your phone at the windows. On-device detection measures real glass, real obstructions, and real orientation, room by room.

Verified GPS confirmed.

A scan captured at the address with a GPS lock becomes a Verified DawnScore, the badge agents put on listings.

The report

Twelve months of light, on one screen.

A DawnScore is hours of usable daylight, month by month, computed from the geometry of this home and the sky it actually gets.

Sample score. 85 Pike St, Seattle. Hours of usable daylight per day.

Golden hour. How it works

Start with a listing link.

  1. Paste any listing link or address.
  2. DawnScore computes a preliminary score from solar geometry in seconds.
  3. Scan with the app for the verified score.

Live scoring is rolling out city by city. Leave your email to be first in line.

Solar geometry

The sun’s exact path over this latitude, longitude, and facing direction, sampled across sixty dates a year. Not an average. This address.

Fifteen years of sky

Historical sunshine and cloud cover for this exact location since 2010. A south window in Portland is not a south window in Phoenix.

The rooms themselves

On-device window detection measures real glass and real obstructions. Nothing leaves your phone but the score.

Detail of the same living room: warm low light pooling across the wood floor.

Renters

One viewing, one decision, and light is the one thing you cannot renovate. Know before you sign.

Buyers

You will live with this light for years. Know before you buy.

Dusk. For agents

Add a verified DawnScore to your listing.

Because great natural light isn’t a measurement. A verified score turns your best feature into evidence: standardized, comparable, worth showing.
