Lull: Fan Noise & Sleep

Nothing loops. Every sound is generated live, so there's no repeat point to lie awake waiting for. Two sounds free every night — no account, no sign-in.

Lull Fan is a fan-noise sleep aid built to feel like a real fan, not a looped recording.

WHY IT'S DIFFERENT

Most white noise apps play you a recording on repeat. Every sound in Lull Fan is generated live, note by note, so nothing repeats over an 8-hour night — there's no loop point for your brain to learn and wait for.

And the speed switch is a real audio control, not a volume knob wearing a fan icon. Turn it up and the sound brightens and quickens, the way a fan's pitch actually changes as its motor works harder. Off, 1, 2, 3, 4 — a switch you slide, not four buttons to aim at in the dark.

FEATURES

• 25 distinct voices — box fan, ceiling fan, oscillating fan, desk fan, air conditioner, deep hum, cabin, open window, distant rain, thunderstorm, ocean waves, waterfall, forest breeze and more. Each has its own character; none is a palette-swapped copy of another.

• Speed that changes timbre, not just loudness.

• A sleep timer with a real fade-out, so you're never woken by silence cutting in mid-breath. It's armed against a fixed end time, so it survives your phone locking, or your headphones falling asleep before you do.

• Lock Screen and Control Center playback, with the remaining time counting down live.

• The fan list is the home screen — swipe through an endless carousel, one full-size fan per page, glass blades spinning behind a wire cage. Tap the fan to start or stop it.

• A calm, glass-forward interface with ambient lighting that responds to fan speed. Built for looking at right before you close your eyes, not for poking around in.

• New sounds arrive on their own, without waiting for an app update.

• Nine languages.

FOR SLEEP, AND EVERYTHING ELSE

Fan noise is the oldest sleep aid there is, and it's useful well beyond bedtime — masking a noisy street, a thin apartment wall, an open-plan office, or the ringing in your own ears. Settle a baby. Hold your focus. Cover the cabin noise on a long flight.

FREE AND PRO

Two sounds are always free, and the pair rotates — the catalog reshuffles every launch, so you keep meeting new fans without paying anything. Want a specific one? Watch a short ad to unlock it for 8 hours.

Pro removes every ad and unlocks all 25 sounds, permanently or as a subscription — your choice. There's also a Remove Ads purchase if you just want the banners gone.

No sign-in. No account. No data collected about how you sleep, because the app never asks.

Built with SwiftUI for iOS 26. Sleep well.
