Krimas
One calendar, one person, one door a day

Make someone an advent calendar they open every day.

Fill each day with photos, voice notes, stickers and words. Send them a code. From the date you pick, one day unwraps every morning until the last one.

HOW IT WORKS

Three steps from idea to the first door

1

Decorate a day at a time

Start from a layout or a blank canvas. Add photos, stickers, text and short voice notes, or hide a surprise under a scratch-off layer.

2

Pick the dates, send a code

Choose how many days and when it starts. You get an 8-letter code to send however you like: a message, an email, a card in the post.

3

They open one door a day

They enter the code in Krimas. Each day unwraps on its date, with an optional morning reminder, and the last one ends on a keepsake of the whole calendar.

PRIVATE BY DESIGN

Made for one person, and only they see it

There's no public feed and no profile to browse. A calendar only reaches the person who enters its code, and once they claim it the code can't be used again.

Read the privacy policy
  • No email or phone number to sign up. A username, a display name and a password.
  • Photos and sounds are stored only so the calendar opens on their phone.
  • Delete a calendar, or your whole account, from inside the app whenever you like.
QUESTIONS

Good to know

Something else? Write to caiwangheng@gmail.com or use Help and feedback in the app.

Does the person I make it for need the app?

Yes. They make an account in Krimas, enter your code, and the calendar appears under Received. Each day opens there.

Does it have to be for December?

No. Pick any start date and anything from 1 to 31 days: a birthday countdown, the days before a trip, an anniversary week.

How many calendars can I make?

Up to 3 at a time. Delete one you no longer need to make room for another. There's no limit on how many you can receive.

Can I keep editing after I send the code?

Until they claim it, yes. Once it's claimed the calendar locks, so what they open is exactly what you made.

What if they try to open a day early?

It stays wrapped and tells them how long is left. They can turn on a reminder for when each day is ready.

What happens if I delete a calendar I've sent?

If nobody has claimed it yet, it's gone and the code stops working. If it's been claimed, it leaves your list but they keep every day.

Give someone a reason to wake up tomorrow.
