Sun Light

Track your daily sunlight automatically with Apple Watch.

Your Apple Watch already measures your time in daylight. Sun Light turns that data into something you can actually use — a daily goal, a progress ring, a streak counter, and a clear picture of when you're getting your light.

  • Automatic tracking via Apple Watch — no buttons to press
  • Daily progress ring, streaks, and customizable goals
  • Morning, afternoon, and evening time breakdowns
  • Home screen, Lock Screen, and Apple Watch widgets

How it Works

Starr AI in three steps

No account. No subscription. No Wi-Fi needed.

1

Download once

Starr AI downloads its model over Wi-Fi one time. After that, everything runs on-device.

2

Go anywhere

On a plane, in the mountains, off the grid — Starr works wherever you are, no connection needed.

3

Just ask

Translate languages, get travel tips, look things up, or have a conversation. Your AI, always available.
