Advent calendars & countdowns
One surprise a day, made by your people.
Boxaday is an iPhone app to prepare a calendar together. Friends, family or colleagues each fill a few boxes with photos, videos, voice notes and messages, and one box opens every day until the big day.

Your calendar
Nobody knows what's inside until it opens.
Each box is filled ahead of time by someone in the group. At midnight, the next one opens for everyone it's meant for, with a little animation and a notification.

Pick the occasion and the dates. Boxaday sets the length, the type and the vibe, from silly to heartfelt.
Invite
Share one link. Everyone who joins helps fill the boxes, and the boxes are shared out between them.
Fill
Each box comes with three theme ideas, or write your own. Add a photo, a video, a voice note, a text or a link.
Open
One box a day at midnight. Laugh, cry a little, and guess who sent what.

Not just for December.
Make one calendar for the whole group, one for each person, or one for someone special.

Features
Small surprises, big feelings.
Every kind of surprise
Photos, videos, voice notes, texts and links, straight from your phone.
Guess who
Some boxes hide who filled them. Let the group play detective.
Opening animations
Confetti, a sealed letter, a snow globe, champagne… someone picks how each box opens.
Ideas for every box
Hundreds of themes, from gentle roasts to heartfelt memories, matched to your group.
Private by design
Only the people in a calendar see its boxes. No ads unless you choose to watch one, and you can delete your account anytime.
Speaks your language
Everyone sees the app and the box themes in their own language.
Start your first calendar.
It takes a minute to set up, and weeks of little moments to open.
