Hey Product Hunt! 👋 I built this because I wanted a clean, no-nonsense tuner that works on any device — no app store, no signup, just open and tune. The 432Hz option is there for those who want it. No agenda — just giving you the choice. Would love to hear how you're using it, and what you'd like to see next. Drone player with more waveforms? Different temperaments? Let me know 🎵
