Choose Your Sleep Goal

Built on Sleep Science

Pink Noise vs White Noise

Pink noise has equal energy per octave, so it sounds softer and less harsh than white noise — many people find it easier to drift off to.

Why Delta Waves Matter

Deep sleep is dominated by slow delta-wave activity. Sleep Chord layers low-frequency tones intended to complement that restful state.

Sleep Consistency

A steady sleep–wake schedule supports your circadian rhythm. Sleep Chord tracks your consistency so you can see it trend over time.

Noise Masking

Steady background sound can mask sudden noises — traffic, voices, a creaking house — that would otherwise fragment your night.
