Why Lowroom

The one you control

No algorithm deciding for you, no fixed recordings — every layer sits on a fader, and the rain has an intensity dial. The weather is in your hands.

Provably never repeats

Three independent sound sources with coprime lengths per color — the combined pattern realigns once every ~50 days. Find two identical seconds and tell us.

The honest one

A free tier with no account and no time cap. A visible cancel button. A 7-day money-back guarantee. Tools shouldn't play games with you.

Lowroom Pro

All seven rooms under your full control: the live mixer with character dials — rain from drizzle to downpour — endless sessions, a sleep timer, and a new room every month. One subscription, every browser.

Common questions

What is brown noise?

Brown noise is a deep, warm rumble — like white noise with the harsh top end removed. Its energy sits in the low frequencies, which is why many people find it easier to work, read or fall asleep to than brighter noise colors.

Why does Lowroom generate sound instead of playing recordings?

Recorded ambience has to loop, and your brain eventually notices the repeat — a tiny distraction every few minutes. Lowroom synthesizes every sample live in your browser, so the sound has never existed before and never repeats.

Is Lowroom free?

Yes — Deep Focus, Rain Room and the 25-minute focus timer are free forever, with no account. Lowroom Pro ($4.99/month or $49/year) unlocks all seven rooms — Deep Focus, Rain Room, Ocean Drift, Night Storm, Fireside, Deep Space and Sleep Descent — plus the live mixer, endless sessions and a sleep timer. And you never buy blind: every Pro room and feature is open for your first 60 minutes on each device — no card needed.

Does it work for studying and sleep?

That's what it's built for: rain sounds and brown noise for studying and deep work, and Sleep Descent with a sleep timer of up to 8 hours for nights. Headphones bring out the low end best.

Do I need an app or an account?

No. Lowroom runs in any modern browser on phones, tablets and laptops. Pro is activated with a license key from your purchase email — no login, no password.

How is Lowroom different from Endel, Brain.fm or Noisli?

Most focus-sound apps either loop recorded audio or let an algorithm decide what you hear. Lowroom takes the third path: everything is synthesized live and every layer stays under your control — a fader for each element, an intensity dial that takes the rain from drizzle to downpour. Add a free tier with no account and no time cap, a visible cancel button and a 7-day money-back guarantee, and you have the version of this idea that stays in your hands.
