We help thoughtful partners build unforgettable relationships

PrimeSync is more than a tracker—it’s your relationship wingman. Log memories, anticipate moods, and show up when it matters.

Turn everyday moments into memorable rituals. By weaving calendar intelligence with cycle insights, it nudges you to send a text when she could use support, book a table before your anniversary, or simply say “I’m thinking of you” on a tough day.

Whether you’re nurturing a new connection or leveling-up a decades-long partnership, PrimeSync is the quiet co-pilot that keeps you thoughtful, organized, and effortlessly on time.

“I used to completely miss the signs when my girlfriend’s period was coming. Now PrimeSync gives me a quiet heads-up, so I show up with chocolate and extra patience instead of clueless jokes. She’s told me more than once that it feels amazing to be understood. It’s honestly strengthened our whole relationship.”
