FREQUENTLY ASKED QUESTIONS
What is the best app for brown noise?
Slo plays continuous, high-quality brown noise tuned for deep sleep and focus, with smooth, gapless playback all night long.
Does brown noise actually help you sleep?
Yes. Studies show deeper noise colors reduce the time to fall asleep and mask disruptive sounds like traffic, snoring, and noisy neighbors - especially effective for light sleepers.
What’s the difference between brown noise, white noise, pink noise, and green noise?
White noise contains all frequencies equally (like static). Pink noise emphasizes lower frequencies (like steady rain). Green noise centers on the soothing mid frequencies of nature. Brown noise goes deepest - like a rumbling waterfall or strong wind. Slo offers all of them so you can find what works best for you.
Is this a good white noise machine for babies?
Yes. Slo works great as a baby sound machine - many parents use white noise, lullabies, or heartbeat sounds to help their baby fall asleep faster and stay asleep longer.
Can I use it for studying and focus?
Absolutely. Many users prefer brown noise or fan noise for deep work, studying, and ADHD focus. Continuous playback helps maintain concentration for hours.
Does it work offline?
Yes. Downloaded sounds play without an internet connection - perfect for flights, camping, or areas with no signal.
Is Slo free?
Slo offers free sounds with a timer. Premium unlocks the full sound library, mixing, and unlimited playback.
Can I mix multiple sounds together?
Yes. Slo lets you layer sounds - combine brown noise with rain, add thunder to a fan sound, or create your own custom soundscape with adjustable volumes.
Does Slo have a sleep timer?
Yes. Set the sleep timer to stop playback automatically - 15, 30, 60 minutes, or a custom duration.
