TrueWave: Binaural Beats

Every tone is generated on your device, in real time — so nothing loops, nothing buffers, and nothing ends mid-session. One payment. No subscription, no account, no ads.

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. Timers fade out over 30 seconds — never a hard cut that wakes you.

KNOW WHAT YOU'RE HEARING Every session shows its real numbers: beat frequency, both carrier tones, wave type. The twin rings on the play screen breathe at the actual beat frequency — they are drawn from the same signal that drives the speaker, not decoration over a recording. Each session explains its frequency band in plain English.

BUILT FOR THE DARK Amber on warm black, with no blue in the palette. Designed to be readable at 3am without wrecking your night vision.

FIVE SESSIONS FREE Deep Sleep, Deep Work, Unwind, Gentle Masking and Recharge are free — one from each of five categories, with no time limit. No paywall until you tap something locked. No popups. No onboarding — it opens straight to the library.

Headphones recommended for binaural beats. Isochronic and pure tones work on any speaker. Sound for comfort and concentration; TrueWave is not a medical device and makes no health claims.
