Black White Card
High-contrast cards for babies
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
High-contrast patterns, ready offline. Choose a card, reverse its black and white colors, and hide the controls while you show it.
Black White Card lets parents and caregivers choose a built-in, high-contrast pattern and show it on its own. The complete set of 20 cards is included. Browse and show them offline without an account; optional Pro removes ads and does not unlock extra cards.
How to use
Choose a pattern from the grid and show it on its own. For a newborn, you can hold the display about 20–30 cm (8–12 in) away, move it gently, and watch for your baby’s interest. Reverse the black and white colors or hide the controls as needed. Return to the grid to choose another card.
Viewing time
Keep any viewing brief and follow your baby’s cues. There is no required number of cards, sessions, or minutes.
A few precautions
Stay with your baby and stop if they seem tired, upset, or turn away. Screen viewing should not replace face-to-face interaction and other everyday activities.
Ratings & Reviews
Updated the app icon and launch screen. Refined how cards open, with clearer feedback after copying contact details or when an information page fails to load.
