Create it
Record a video or a voice note, write a few words, or upload a video, photo or audio file you already have. Play it back before you keep it.
Record a video, a voice note or a letter now. One4Future seals it until its moment - a date, their 18th birthday, the day something happens - and delivers it then.
Your first capsule is free
Record a video or a voice note, write a few words, or upload a video, photo or audio file you already have. Play it back before you keep it.
Choose when it arrives: a date, their birthday at 9am their time, or a moment people you trust confirm has happened. Until then, nobody can open it.
On the day, we email them a link. The first time they open it, sparks rise and the envelope opens. Then they watch, listen or read, and save or share it if they like.
They can send a video, a voice note or a few words straight back. Only you see it, and we let you know it has arrived.
Everything you need to leave a message that lands at exactly the right time.
Pick the age - 18, 21, 40 - and it arrives at 9am on that birthday, in their time zone, even decades from now.
A wedding, a graduation, a first home. Choose up to five people who will confirm it has happened; it's delivered 24 hours later, so there's time to catch a mistake.
Record in the app or upload from your phone.
Recipients can save a message to their gallery or share it.
Unseal to edit, or revoke, any time before it's delivered.
Legacy capsules wait for all of these, in order - and any step can stop it.

No. When their capsule arrives we email them. They open it in the One4Future app, signed in with that email address.
Yes, until it's delivered. Unseal it to edit, or revoke it so it's never delivered.
Up to 50 years. Birthday capsules arrive at 9am in the recipient's own time zone.
It takes all of it: missed check-ins, weekly reminders through a grace period, both of your trusted people confirming, and a final week after we email you a last warning. Checking in at any point, or one trusted person saying you're fine, stops it.
Your first capsule is free. After that you pay per capsule, once, when you seal it; prices will be announced before launch. Opening, saving and sharing a capsule you receive is always free.
In any modern browser, on a computer or a phone, and in the Android app. The iPhone app is coming soon. It's one account everywhere: sign in with the same email address. Recording in the browser is coming; on the web you can write letters and upload videos, photos and voice notes.
