The Vault home screen: together for 849 days, day 47 on the path, tonight's question

One night in the Vault

Every night, you both write one line.

  1. 21:12 · Tonight

    The app asks you both one question.

    Tonight: What do you hope Luca felt today?

  2. 21:14 · Her line

    Sofia writes her answer and adds a photo of today.

  3. 21:15 · Sealed

    Her answer is locked.

    Luca can't read it until he writes his.

  4. 22:40 · His turn

    Luca gets one message: Sofia has written. Your turn.

  5. 22:41 · Kept

    He writes his. Both answers open at the same time.

    That counts as one kept day.

  6. Tomorrow · The album

    Both answers are saved as two polaroids.

    Every kept day adds two more.

The path to the engagement ring

Hardest ring to ever claim.

You can't buy it. You get it by writing to each other every night for a year. Miss a day and you lose one. At day 365, THEONE designs it with you and makes it once.

Kept days 0 / 365
  1. Day 60

    First gift unlocks, for the two of you.

  2. Day 120

  3. Day 200

  4. Day 365

    THEONE contacts you. Your engagement ring gets designed with you and made once.

You see what each gift is on the day you reach it. Every gift you take lowers the price of the ring by a fixed amount.

Day 365 in the Vault: the path is complete and a letter is waiting

Day 365

At day 365 a letter from THEONE opens in the app.

That is where your ring starts. Only couples who kept 365 days ever see it.
