## What is Ch'ti Fan?

Ch'ti Fan reproduces the soothing sound of a real fan to help you fall asleep, mask street noise, or create a focus bubble.

No ads, no account, no subscription. One-time purchase, forever.

WHY A FAN
The steady airflow of a fan produces a structured white noise that masks disruptive sounds (neighbors, traffic, snoring), helps you fall asleep faster, and improves sleep quality. It's also great for naps, deep-focus work, or soothing a baby.

6 SOUNDS
• Desk fan — light hiss, gentle oscillation
• Pedestal fan — wide airflow, strong rotation
• Air conditioner — low hum, steady tone
• Pure white noise — flat spectrum, no modulation
• Pink noise — more natural than white, balanced
• Brown noise — very deep, like ocean waves

CONTROLS
• Volume — adjustable from 0 to 100 %
• Oscillation — simulates the slow rotation of the fan's head
• Sleep timer — Off, 15 min, 30 min, 1 h, 2 h, 4 h, 8 h
• Gentle fade-in on start, 30-second fade-out before auto-stop
• Continuous playback when screen is locked
• Dark mode interface optimized for nighttime use

WHAT CH'TI FAN DOES NOT DO
• No ads
• No subscription (one-time purchase, lifetime)
• No data collection: no account, no analytics, no internet connection

The app works 100% offline and never sends any data to any server.
