The frequency detector that fits in your pocket.
Point your phone at any speaker. HZ Detect samples the notes, reveals the real tuning (432, 440, 444, or any Solfeggio target), identifies the song, and offers a one-tap link to hear it retuned to 432 Hz or 528 Hz.
100% free. Audio is analyzed on your device and never uploaded.
A 30-second listen captures the notes and matches them against tuning tables for 440, 432, 444, and every Solfeggio frequency.
Built-in song recognition names the track and artist while the tuning analysis runs — no extra taps.
One tap opens the identified song retuned to 432 Hz or 528 Hz, based on what was detected.
HZ Detect Pro — exact measured tuning (e.g. 434.7 Hz), unlimited history, no ads. One-time $14.99, synced to your account across devices.
Mobile checks what's playing around you. The desktop flagship analyzes every file you own and retunes songs from their measured tuning to your target — in batch, on your computer.
