$19.99 · In‑App Purchases
Your music. Retuned to 528 Hz in real time. Try 20 songs free — no subscription, no catch. One unlock. Yours forever.
What if your favorite music could sound and feel different — not by changing what you hear, but by shifting the frequency beneath it?
528 Player Plus retunes any song from your library to 528 Hz — the Solfeggio frequency associated with harmony, restoration, and the natural resonance of living systems — in real time, as it plays.
No exports. No waiting. No audio files to manage. Just press play.

Most modern music is mastered at 440 Hz, the global standard tuning. 528 Player Plus shifts the playback frequency of your existing music library to 528 Hz on the fly — so every song you already love plays at this resonant frequency without altering your original files.

WHY 528 Hz?
528 Hz sits within the ancient Solfeggio scale — a set of tones used in sacred music across cultures for centuries. Modern researchers and sound practitioners have associated this frequency with feelings of clarity, calm, and coherence. Whether you approach it scientifically or intuitively, the experience speaks for itself.
Try it with music you already know by heart. You may be surprised.
FREE TO TRY. YOURS TO KEEP.
