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.
