Read full description

Only one of you needs the app. Kept gives you small daily rituals, most just a minute or two, then helps you send them to your partner by text. They just reply. No download, no account, no cost for them. Busy weeks shouldn't cost you your relationship. 2 MINUTES A DAY. THAT'S IT. Answer a few questions about your relationship and Kept builds your plan: a handful of fresh rituals every day, matched to your love language and what you want to grow together. Pick any one, check it off, and keep your shared streak alive. GAMES THAT GET YOU TALKING AGAIN A little game, every night. Most take under 10 minutes: - Question Deck: pick a depth, flip a card, talk - This or That: pick a side, then guess your partner's - How Well Do You Know Me?: guess their answer, score points - Never Have I Ever: five fingers each, last hand standing wins - Appreciation: finish the line and send a love note - Date Generator: set the budget, spin the wheel SEE WHERE YOU'RE CONNECTING Your Connection Map shows where you two are strong across Intimacy, Communication, Presence, Repair and Hope, plus one area to grow. YOUR STORY, ONE NIGHT AT A TIME A nightly prompt and private Memory Journal turn one line a night into the story of you two. Count your days together, see your anniversary coming, and look back on every ritual and entry in your calendar. BUILT ON THE SCIENCE OF LOVE Kept is grounded in relationship research: small, repeatable moments of connection add up in a way grand gestures rarely do.
