About

THEONE Vault

Features
Read full description

The Vault is the app that comes with every THEONE ring. It is private. Only the two of you are inside. HOW IT WORKS Every night the app asks you both one question. You write your answer. Your partner writes theirs. Both answers open at the same time. That counts as one kept day. WHAT IS INSIDE One question every night, answered by both of you. One photo a day. They become your shared memories. Letters you can seal until a day you choose. Small games for two. A counter of your days together. THE HARDEST RING TO EVER CLAIM There is a ring you cannot buy. 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 your engagement ring with you and makes it once. FREE FOR LIFE The Vault is free for life with your THEONE ring. You open your vault with your ring order number, then invite your partner.
