## What is Ortus?

Ortus is a light instrument. It shows the sun where you stand: rising, climbing, setting. Through the day it tells you what that light is doing for your body and when to go out into it.

Each morning you bank a dose of light toward a simple daily goal. Ortus counts it, holds your streak, and shows the week behind you and the days ahead. In the evening it dims with the sky and tells you when to wind down.

No accounts. No data leaves your phone. Just you and the sun, kept in rhythm.

What Ortus does
- Shows the sun's real position where you are
- Tells you the light to seek through the day
- Banks your daily light toward a clear goal
- Estimates the vitamin D you make, from the sun's height and your skin
- Holds your blood test and carries the figure forward between labs
- Imports a D-Minder history
- Keeps your streak and a five-day forecast
- Reads the sky through your camera to gauge cloud cover
- Dims at dusk and reminds you to wind down
- The science behind each phase, in plain words

The vitamin D figures are modeled from the sun and your skin, not measured. Ortus is not a medical device.

## Version history (last 5 releases)

### 1.7.3 — 2026-10-27

At the largest text sizes, the live session now keeps every word whole. Pause and Done stack, each the full width, and the figure in the ring keeps its unit.

### 1.7.2 — 2026-10-26

Fixes a crash when typing a very long blood test value, and a re-imported export no longer counts a session twice. At the largest text sizes, the session summary and the first onboarding pages now keep every word whole.

### 1.7.0 — 2026-10-22

At the largest text sizes, Settings now keeps its words whole. Each switch and button moves under its title and note, and page and card titles no longer break inside a word.

### 1.6.4 — 2026-10-21

At the largest text sizes, the planning sheet and the Lab chart now fit. The skin and cloud scales no longer break inside their words, and the Lab chart gives each guideline its own line.

### 1.6.3 — 2026-10-15

Reading the sky now takes less work from your phone. The camera runs only as fast as the reading needs. The picture and the reading are unchanged.
