## What is Baby Contrast?

Newborns see the world in bold contrast. Baby Contrast turns that stage of development into calm, active play your little one can actually respond to.

Show your baby a full-screen high-contrast card, and every tap makes the shape react with gentle motion and a soft sound. It is not a passive video to stare at, it is something baby helps make happen.

WHY BABY CONTRAST
- Grows with your baby: black and white for newborns, a touch of red from about 3 months, playful color from about 6 months.
- Touch to react: shapes swell, spin, flip and sparkle with soft, cycling tones. Every tap feels a little different.
- Made for tiny eyes: bold, simple shapes drawn to be clear at close range. No harsh flashing.
- Gentle by design: a quiet session timer nudges you to take breaks, because newborns do best in short bursts.

CALM FOR PARENTS, TOO
- No ads, ever.
- Works fully offline.
- No account, no sign-up, nothing collected.
- One-time purchase unlocks every card. No subscription.

## Version history (last 3 releases)

### 1.1.0 — 2026-08-25

New in this update:

• Follow-Me mode: a shape drifts slowly across the screen for eye-tracking practice — like a mobile, in your pocket. Tap it for a gentle bounce and sound
• 8 new cards: Waves, Zigzag, Flower, Moon & Stars, Kitty, Triangles, Rainbow and Butterfly — each in every color stage (18 cards total)

As always: no ads, fully offline, one-time purchase.
