Marivio — Wedding Planner puts shared wedding planning information in one plan for two partners. The guest list tracks RSVPs, plus-ones, meals, dietary notes, and contact details, while seating tools support round, banquet, and head tables. Couples can compare estimated and actual spending by category, track bookings and due amounts, and use a checklist that runs from twelve months before the wedding to the final week. A run-of-show timeline helps organize the event day, with countdown widgets that can show what is happening now and next. The app works offline and syncs between partners through their own iCloud; the developer says no account or sign-up is required. Marivio is available in English and Polish. Its optional Plus unlock is a one-time purchase with Family Sharing, though the listing does not state the price.
