CatLight: Book & Reading Light

Use your screen as a warm book lamp with swipe brightness and color control

Use your phone as an adjustable reading light for physical books, magazines and notes. CatLight fills your Android screen with a steady glow, so you can read at night without turning on a bright room light.

You do not need sliders or a control panel to adjust the light. Adjust everything directly on the screen:

- Swipe up or down to change brightness from dim to bright.
- Swipe left or right to move between cool white, neutral and warm amber tones.
- Keep the screen awake while you read.
- Return to your last brightness and color temperature the next time you open CatLight.

A warm book light for night reading

Choose a warmer tone for a softer bedside glow, or move toward a cooler white when you need a clearer view of the page. The full-screen light spreads across a nearby book more gently than a small rear camera light.

Simple by design

CatLight opens straight to the light. The screen itself is the control surface, so you can adjust your reading lamp without searching through menus or interrupting your book.

Use CatLight as a:

- Reading light for paperback books and magazines
- Book light for reading in bed
- Small screen lamp in a hotel room, train or plane
- Warm bedside light for a dim room
- Soft phone light when a rear camera light feels too harsh

How to use it

1. Open CatLight.
2. Swipe vertically to set the brightness.
3. Swipe horizontally to choose a warm, neutral or cool tone.
4. Place the screen near the page and start reading.

CatLight is a focused screen light for readers who want fast, adjustable illumination without a complicated interface.
