Slo generates continuous, high-quality brown noise specifically tuned for deep sleep and focus. Unlike looped recordings, Slo creates endless unique audio that never repeats. Does brown noise actually help you sleep? Yes. Studies show brown noise reduces the time to fall asleep and masks disruptive sounds like traffic, snoring, and noisy neighbors. Slo's deep-frequency brown noise is especially effective for light sleepers. What's the difference between brown noise, white noise, and pink noise? White noise contains all frequencies equally (like static). Pink noise emphasizes lower frequencies (like steady rain). Brown noise goes even deeper - like a rumbling waterfall or strong wind. Slo offers all three so you can find what works best for you. Can I use it for studying and focus? Absolutely. Many users prefer brown noise for deep work, studying, and ADHD focus. Slo's continuous playback helps maintain concentration for hours. Does it work offline? Yes. All sounds in Slo are generated on-device and work 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 white noise, or create your own custom soundscape with adjustable volumes. Does Slo have a sleep timer? Yes. Set a timer to automatically stop playback after you fall asleep - 15 minutes, 30 minutes, 1 hour, or custom duration. Is brown noise better than white noise for babies? Many parents find brown noise more soothing for babies because of its deeper, gentler frequency. Slo offers both so you can test which helps your baby sleep best.
