Simple as writing
a letter

1

Choose your message type

Record a voice note, write a letter, take a photo or shoot a video. Add text, stickers and filters with our Snapchat-style editor.

2

Choose who it's for

Find them by their @username on WhenIt. Your message stays completely sealed — they won't know it exists until the moment arrives.

3

Set the perfect trigger

A specific date. Their birthday, every year. When they graduate. When they turn 18. When they walk into a specific place. Or when you are no longer here.

4

Seal it and forget it

WhenIt holds your message safely until the exact moment you chose. Then it delivers itself — no action needed from you.

🔒
Your message is sealed
Encrypted and stored until the trigger moment. Not even WhenIt can read it.

What people seal
with WhenIt

I recorded a voice note for my daughter to open on her wedding day. She doesn't know it exists. I wrote it when she was seven.

Michael T.
Father · London

I left an Echo at the bench where I proposed. She'll find it one day when she walks past. I can't wait for that moment.

James R.
Engineer · Edinburgh

I sealed a letter for my son for when he turns 18. I wrote it the day he was born. WhenIt will deliver it without me having to remember.
