Find them by their @username on WhenIt. Your message stays completely sealed — they won't know it exists until the moment arrives.
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.
WhenIt holds your message safely until the exact moment you chose. Then it delivers itself — no action needed from you.

⭐ PremiumA trusted contact confirms when to send.
People leave voice notes, photos and messages pinned to real places — a bench, a corner, a view that changed everything.
Walk nearby and discover what strangers left behind. Echoes unlock when you are within 50 metres. Some things require you to show up.
Record your real voice. Nothing carries warmth like hearing someone speak your name in their own voice.
Write everything you never quite said. Use the AI writer if the words won't come on their own.
Add text, stickers, GIFs and filters with a Snapchat-style editor directly on your photo.
Your face, your eyes, your voice. The most personal message you can leave for someone.
Your message is encrypted and stored until the trigger fires. Not even WhenIt can access the content.
Change your mind? Edit the content, trigger or date at any time before delivery. Only the recipient is fixed.
No ads. No selling your data. Just a small subscription that keeps your messages safe forever.
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.
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.
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.
