Questions? Answered.
The honest answers, no fine print.
How does this work without recordings?
Every sound is synthesized live in your browser using the Web Audio API. Colored noise, filtered noise, and mathematically generated patterns β like a real white-noise machine, but for your whole soundscape.
Will this actually help me sleep?
That's the whole point. Natural, steady sounds mask disruptive background noise and give your brain a predictable soundscape to settle into. It's the same principle behind the best-selling sound machines.
Does it work on my phone?
Yes β any modern phone browser (iOS Safari, Chrome, Android). No app store, no install. Perfect for travel.
Can I really cancel anytime?
Yes. One tap, no hoops, no "retention" callbacks. You keep the app until the end of the billing period.
What if I just want the free version?
Enjoy it! Free previews give you 10 minutes of any sound. When you want an all-night mix, that's what Premium is for.
