$4.99 — one-time purchaseWhat it does
Built for winding down.
Lull is for the moments between things — the half-hour before sleep, the work session that needs to start, the quiet you can't quite find. Pick a few sounds, slide the volumes until it feels right, and let it run.
Layer up to eight sounds
Build your own mix from over forty ambient sources. Independent volume on every track. Crossfading loops you won't hear seams in.
Sleep timer with fade
Pick a duration. Lull plays steadily, then fades to silence over the last stretch — gentle enough not to pull you back.
Bedtime reminders
Set a time and Lull will nudge you gently when it's near. No pressure — just a soft "time to wind down."
Save your mixes
The combination that helps you sleep tonight is the one you'll want again tomorrow. Save it, name it, come back to it.
The library
For the deeper end of the library
Tones tuned to a frequency.
Most of Lull is recorded ambience — rain, wind, coffee shops, a fire. But two categories work differently: pure tones tuned to specific frequencies, layered quietly under everything else. They're best felt more than heard.
Brainwave tones
Isochronal pulses tuned to the rhythms your brain produces in different states. The idea: a steady pulse may give your brain something to settle into.
- Delta2 Hzdeep sleep
- Theta6 Hzdrifting, dreaming
- Alpha10 Hzrelaxation
- SMR13 Hzcalm focus
- Beta16 Hzalert focus
- Gamma40 Hzclarity
Solfeggio frequencies
Ten pure tones from the solfeggio scale, part of meditation traditions for decades. Plain sine waves at carefully chosen pitches — soft enough to disappear under a soundscape.

- 285 Hzrenewal

A note on the science: neither set has rigorous clinical backing. They're tools to layer and experiment with — not medical claims. People find what works for them.
