TrueWave: Binaural Beats

TrueWave generates binaural beats and pure tones in real time — no audio files, no streaming, no account. A precise instrument that makes sound, and tells you exactly what sound it is making. PAY ONCE. NO SUBSCRIPTION. EVER. $14.99 unlocks everything, forever. No ads. No account. No tracking. TrueWave has no servers and sends no telemetry. Apart from Apple's purchase and restore checks, it runs identically in airplane mode. IT DOESN'T STOP Every tone is synthesized live, so there is no loop to end and no track to run out. Choose 30 minutes, 1 hour, 2 hours, or the infinity timer and let it run all night.
