TrueWave: Binaural Beats

TrueWave is a real-time tone instrument for binaural beats, isochronic pulses, pure tones, and ready-made presets. Every signal is synthesized live on your device — nothing recorded, nothing looped.

THE INSTRUMENT Build an exact signal from the first screen. • Binaural — set a beat from 0.5–40 Hz and a carrier from 20–1000 Hz • Isochronic — set a pulse frequency and carrier tone • Pure tone — set a steady carrier from 20–1000 Hz Use the slider for broad changes, −/+ for fine steps, or tap the number to enter an exact frequency.

START WITH A PRESET 29 starting points cover nighttime listening, focus, relaxation, sound masking, deep rest, Solfeggio pure tones, and multi-stage programs. Five presets are free with no time limit: Deep Sleep, Deep Work, Unwind, Gentle Masking, and Recharge. Open any preset to inspect its real signal details before you play it.

SEE WHAT IS ACTUALLY PLAYING TrueWave keeps the visual instrument tied to the signal: • Binaural shows the left and right carrier frequencies • Isochronic uses a single pulse display for one modulated carrier • Pure tone shows a steady carrier with no beat label • Multi-stage programs update their live frequency as the program moves between stages

LONG LISTENING, WITHOUT A TRACK ENDING Choose 30 minutes, 1 hour, 2 hours, or an unlimited timer. Timers finish with a 30-second fade instead of a hard cut. Because the signal is generated in real time, there is no recording or loop that runs out.

ONE-TIME OWNERSHIP Unlock TrueWave once for all presets and custom Instrument playback. No subscription, no account, no ads, and no tracking. Restore Purchase is always available.

PRIVATE BY DESIGN TrueWave has no account system and no analytics backend. Apart from Apple purchase and restore checks, the audio instrument runs on your device.

BUILT FOR THE DARK Warm black, bone, and amber keep the interface restrained at night. The app also supports Dynamic Type, Reduce Motion, iPhone, and iPad layouts.

Headphones are recommended for binaural beats because each ear needs a different carrier tone. Isochronic and pure tones can play through speakers. TrueWave is a sound tool, not a medical device, and makes no health claims.
