C3 is relationship intelligence, not a horoscope app. It reads Western astrology the way a behavioral scientist would: as data about how people communicate, make decisions, handle friction, and build trust. Then it translates all of it into plain, grounded language. No fate. No soulmates. No mysticism. Just a sharper read on the people in your life and the ones you're about to meet. WHAT YOU GET • Your Blueprint. A psychological profile built from your birth chart. Your patterns, your blind spots, and how you operate under pressure, in words instead of symbols. • Discover & Orbit. Meet people across four kinds of connection: Friendship, Dating, Business, and Creative. Every match comes with a behavioral breakdown of why you'd click and where you'd rub. • Compare. Put two charts side by side and see how your placements meet someone else's across every planet and house. You get plain-language reads on where you click and where you'll rub, for anyone you connect with or run a report on. • Daily Pulse. A short, honest read on the day's energy, a mood check-in, and a private journal. Built for reflection, not doomscrolling. • Reports. Run a compatibility read on anyone, even if they're not on C3. Enter a birth date and get the same grounded analysis. • Cosmic Guide. An AI that knows your chart and talks like a thoughtful friend, not a fortune teller. LOW-PRESSURE BY DESIGN Every action is a clear, tappable choice. No forced swiping, no games, no dark patterns. YOUR DATA STAYS YOURS Birth details are sensitive, and we treat them that way. Encrypted, separated from your identity, and never sold. Delete your account and everything goes with it.

Verdict
The clearest difference is rating: C3 at 5.0 against MyAffinity's 4.5. C3 also leads on update cadence (every 3 weeks vs every 6 weeks). MyAffinity's advantage is in-app purchases (none vs 2) and ratings volume (15 vs 2). On price, ads and device support there is nothing between them.
