Keep every card.

There’s a box somewhere in your house.

Birthday cards. A note from your grandmother. The one your kid drew when they were six.

Scan one, and it opens like the real thing.

The front and the back, laid flat.

Then the message inside.

The handwriting and all.

Now it’s yours to turn.

What it does

A card you were sent five years ago, never more than a few seconds away.

📸

Scan in seconds

The front and the inside. Kaartje finds the edges and straightens it out for you.

📜

Opens in 3D

Every Kaartje folds out on screen exactly like the one in the box.

🔍

Search anything

Who sent it, the occasion, even the scribbles inside.

🎉

Group into moments

A wedding, a hospital stay, one very good birthday.

✍️

Note why it mattered

Who it’s from, and the bit you don’t want to forget.

📱

Home Screen widget

Resurfaces a card from this day in past years.

Where your cards live

On your device, and in your own iCloud. There’s no account to make, no server of ours holding your cards, and nothing for anyone here to read. They sync between your devices because they’re yours — not because they’re ours.

Pricing

Keep five Kaartjes free. After that it’s a one-time purchase — one payment, no subscription.
