We plan the wedding — never the life. Vow Prep is for two people about to build a life together: engaged, moving in, getting a PACS, or simply committing for real. Before you merge two lives, there are conversations worth having — honestly, and out loud. Playful, but real. Swipe through beautifully written cards across 9 decks that sweep every corner of life as a couple: - Start Here - the warm-up - Money - spending, saving, "yours, mine, ours" - Kids - if, when, how - Family - in-laws, boundaries, traditions - Intimacy - closeness, needs, expectations - Values - what you stand for - Conflict - how you fight and repair - Meaning - faith, purpose, whatever you each believe - Daily Life - chores, space, routines Answer together, apart. Each of you keeps the app on your own phone, answers a card privately, then reveals both answers side by side - and talks. Honest, a little vulnerable, always yours. One-time unlock. Buy it once, keep every deck forever. No subscription. Before you say "we", have the conversations that matter.
