LAVNI FTC TILL THEN. Some things are worth waiting for. A letter to the person you will become in ten years. A photo your child will open on their eighteenth birthday. A hundred voices gathered for one occasion, sealed until the day they are meant to be found again. Lavni sends something forward in time. Write a message. Add photos, videos or a voice recording. Choose the exact moment it opens — months, years or decades from now. Until then, the capsule stays closed. Not today. Not by accident. Not before its time. HOW IT WORKS 1. Create your capsule Write what you want the future to read. 2. Add your memories Photos, videos, voice recordings. 3. Choose the opening date The exact day and hour it unlocks. 4. Keep it private, or invite others Share it with the people it belongs to. 5. Seal it, then wait When the countdown ends, the capsule opens itself. Till then. PRIVATE CAPSULES Something for yourself, or for one person. A letter to your future self. A message for someone you love. A moment kept exactly as it is today. You decide when it opens. Nobody reads it before — not even you, unless you use the six-digit secret code Lavni shows you once, when you seal it. COLLABORATIVE CAPSULES Some moments are better built together. Invite friends, family, classmates or colleagues with a private link or a QR code. Each of them adds their own message, photo or video, without creating an account. When the contribution window closes, the capsule seals itself. Everyone then waits for the same morning. Made for weddings, births and first years, birthdays and graduations, family archives, class projects, team milestones, and letters to your future self. PERSONALISED CAPSULES Choose what the capsule is for, its theme and its colour: they greet whoever opens it. Up to five photos, videos or recordings, and your loved ones can add theirs if you wish. DESIGNED TO STAY SEALED A memory deserves more than a reminder. Message text, titles and email addresses are encrypted with AES-256 before they reach our database. Photos, videos and audio are held in private storage, reachable only through short-lived signed links. Every capsule has its own private link, long enough that it cannot be guessed. Private capsules come with a secret code for early access. Attempts are limited, and repeated failures lock it. Opening dates are enforced on our servers, not on your phone. Changing the date on a device opens nothing. Sealed with Lavni means sealed until the day it was meant to come back. TWO DOCUMENTS, TWO MOMENTS The invitation card, while a collaborative capsule is still gathering. It carries the QR code and the short code your guests need, the closing date, and how many people have already contributed. The day the capsule seals, the card stops working. Its purpose is complete. The certificate of sealing, once the capsule is closed. It records the title, the real date it was sealed, the date it will open, and a reference anyone can verify at lavni.fr. Until the opening date, the certificate only proves that something exists, that it is sealed, and that its time has not yet come. From that date, its QR code opens the capsule: keep a certificate as you would keep a key. Both are A4 PDFs, set in real typography with an engraved frame and a struck seal. Made to be printed, kept, framed or handed out. AFTER THE OPENING An opened capsule stays available for 30 days, then it is deleted for good, with all its files. Lavni reminds you by email first: download what you want to keep. WHAT IS FREE Simple capsules are free. One message, one recipient, sealed until your date. No account needed. Everything else is a one-off purchase. You buy a capsule, not a subscription. Nothing renews and nothing is charged again. AVAILABLE IN English, Français, Español Today becomes a memory. Create something now. Leave it untouched. Let time do the rest. LAVNI FTC TILL THEN.

Verdict
The clearest difference is in-app purchases: Hayo at none against Lavni's 9. Hayo also leads on iOS requirement (12.0 vs 16.0). On price, ads and device support there is nothing between them.
