Sleep Timer - Soothing Sounds

Most sleep timers cut sound abruptly, waking you up. We rebuilt it from the ground up. All sounds are generated on-device, requiring no internet or downloads.

◆ Undetectable Fade
・Most timers cut sound linearly, making the silence itself a wake-up trigger
・This app uses a perceptual curve (logarithmic) to lower volume slowly and smoothly
・It doesn't go to zero, but rests on a subtle "noise floor," removing the jarring drop into silence

◆ Customize to Your Sleep Pace
・No fixed presets; use a continuous slider to set fade duration from 1 to 30 minutes
・Adjust perfectly for nights you fall asleep fast or struggle to drift off
・Timer length is also customizable from 10 minutes to 2 hours

◆ On-Device Sound Generation
・Synthesizes Brown Noise, Gentle Rain, Warm Pads, and Pink Noise in real-time
・No loops means no seams and no repeating patterns
・Auto-quickens fade when screen turns off to aid sleep onset
・Continues playing with screen off, showing a gentle countdown on a dark, soothing interface
