Noise is a simple iOS app that plays five types of comfort noise — white, pink, brown, mosquito repellent (17kHz), and pest repellent (20kHz). With a built-in timer and volume control, it's your go-to sound companion for deep work, relaxation, sleep, and keeping insects at bay.
Choose from white noise, pink noise, brown noise, a 17kHz mosquito repellent tone, and a 20kHz pest repellent tone. One tap switches between them instantly.
Set a timer for 5, 15, 30, or 60 minutes and let the app stop automatically. Great for falling asleep or taking timed breaks without touching your phone again.
Adjust the volume with a simple slider to find your perfect level — from a gentle background hum to full masking of surrounding noise.
Play a 17kHz tone said to repel mosquitoes, or a 20kHz tone said to deter mice and other pests. Try it outdoors or before bed. (Note: effects are not scientifically proven.)
White, pink, and brown noise for focus and sleep — plus high-frequency tones at 17kHz and 20kHz for repelling mosquitoes and pests. Switch between them with a single tap.
Choose from 5, 15, 30, or 60 minutes. The app stops automatically when time's up — no need to reach for your phone. Perfect for sleep, naps, or Pomodoro sessions.
Drag the slider to set your preferred volume in real time. Play it softly in the background or crank it up to mask loud environments — whatever works best for you.
The app includes a 17kHz tone said to repel mosquitoes and a 20kHz tone said to deter rodents and other pests. Use it when you're outdoors or sleeping in a room you're not sure about. (Note: effects are not scientifically proven.)
Tap any noise from the list and it starts playing immediately. Choose white, pink, or brown noise for focus or sleep, or select the mosquito or pest repellent tone for outdoor or nighttime use.
Drag the volume slider to your comfort level, then choose a timer if you want the sound to stop automatically. With no timer set, it plays continuously until you stop it manually.
Once playing, you can close the app and the sound keeps going in the background. Work, read, sleep, or just unwind — Noise runs quietly in the background so you don't have to think about it.
