01 — The problem

Most marriage programs end when the retreat does — the workbook goes on a shelf and the momentum dies. The ministry wanted its curriculum to become a daily habit instead of an event: warm and private, something a couple comes back to. Pastoral, not gamified — no streaks, no guilt — and each spouse's answers truly private until they both choose to share.

02 — What we built

Each day, both spouses answer a short prompt on their own, and neither sees the other's words until both have answered. The database itself enforces that reveal, so the privacy is real. The moment lands in the app and on an iOS home-screen widget, woven into the day. Around that core sit the curriculum's tools: a couples assessment, a shared mission portrait, an eight-session journey, and an AI coach that stays inside the material and routes real crises to a human.

  • Both spouses answer a short daily prompt on their own; neither sees the other's words until both have.
  • The reveal is enforced by the database itself; it can't be faked from the client.
  • The moment appears on a native iOS home-screen widget before the app is ever opened.
  • A couples assessment and a shared mission portrait personalize the experience from day one.
  • An AI coach stays grounded in the curriculum and routes any real crisis to a human — tested against 34 crisis scenarios.
03 — The result

In beta ahead of the September retreat pilot. The privacy model has been tested adversarially: 40 database-level isolation checks confirm neither spouse can reach the other's words early, and the AI coach held its ground across all 34 crisis scenarios.
