About

Relationship Tracker

Buffaly is the relationship app for couples who are already together, not for meeting someone new. You and your partner share one heart. It starts at 0% and only grows when one of you logs a real moment of connection: a kiss, a hug, really listening, a proper conversation, a surprise, a date, or something more. Left alone, the heart slowly decays, so showing up for each other stays something you keep choosing, not a one-time checklist. 14 ways to grow it together: Little Reminder, Touch, Hug, Kiss, Listen, Conversation, Little Surprise, Have Fun, Get Naughty, Date, Compliment, Call, Help Out, Try Something New. Build a streak by reaching 100% together each day. Tapped the wrong one? One tap undoes the last action for both of you. Keep your heart in sight with Home Screen and Lock Screen widgets. Earn credits by reaching goals together and spend them in the shop on themes and app icons. Add one shared couple photo. No signal? Log your moment anyway, it syncs later. Available in English and German. Buffaly gently nudges whichever partner needs it, at the right moment, based on where your heart actually stands and what you both respond to. Never generic. This is private, just the two of you. No public profiles, no feed, no strangers. Your heart is shared with exactly one person: your partner. Try it free for 7 days. One subscription covers you both: whoever subscribes unlocks it for the couple, not per person. Renews automatically, cancel anytime in your Apple Account settings. Small moments, noticed and remembered. That's the whole idea. Terms of Use: https://getbuffaly.com/terms Privacy Policy: https://getbuffaly.com/privacy
