Box Fan Sounds for Sleeping

Can't sleep without a fan? Whirr gives you fan sounds for sleeping, brown noise, white noise and rain sounds that play all night, without ads and without a paywall in front of the sounds. Every one of the 20 sounds is free, forever.

WHY WHIRR
Many sleep sounds apps lock most of their sounds behind a subscription, play ads, or cut out in the middle of the night. And a recording on repeat has a seam: once you notice the loop every few seconds, you can't stop hearing it. Whirr generates every sound live on your phone. Nothing is a recording, so nothing loops and there is no seam to hear. The box fan you fall asleep to sounds the same at 3 a.m. as it did at midnight.

20 SOUNDS, ALL FREE
• Noise: white noise, pink noise, brown noise, deep brown noise
• Fans and machines: box fan, ceiling fan, air conditioner, airplane cabin, hair dryer, night train
• Nature: rain, thunderstorm, ocean waves, stream, wind, fireplace, crickets
• Soothing: womb with heartbeat, shush, cat purr

FREE, WITHOUT A TRIAL
• All 20 sounds, generated live, never looping
• Mix up to 3 sounds, each with its own volume and one character control (tone, speed or intensity)
• 12 ready-made mixes to start with
• Sleep timer with a gentle fade-out
• Plays reliably all night, also with the screen off. If you like, it keeps playing alongside other apps and notifications
• Quick settings tile to start your sound without opening the app
• No ads, no account, no tracking
• Works offline: no internet needed to fall asleep

FOR SLEEP, NAPS AND FOCUS
Use a fan noise for sleeping, brown noise to drown out a noisy street, rain sounds for a nap, or white noise to focus while you work or study. Whirr helps you fall asleep and masks the noises that keep you awake.

HOW IT WORKS
1. Pick a sound or one of the ready mixes.
2. Adjust volume and character until it sounds right to you.
3. Set a sleep timer if you want it to fade out, or let it play until morning.

FREE VS PRO
Every sound stays free. Pro adds tools for people who use Whirr every night:
• Smart Mask (optional): uses the microphone to measure how loud your room is in real time and briefly raises the noise when a snore, a passing car or a barking dog shows up. Nothing is recorded or stored
• Night curves: ease the sound down after you fall asleep, deepen it through the night, or add a morning shield before your alarm
• Sound shaping: adjust low, body and air of each sound
• Up to 6 layers in one mix instead of 3
• Unlimited saved mixes
Pro is available as a monthly or yearly subscription. The yearly plan comes with a 7-day free trial.

PRIVACY
Whirr has no ads, no account and no tracking. Everything happens on your phone, and Whirr only goes online when you buy something.
