## Description

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.<br><br>◆ Undetectable Fade<br>・Most timers cut sound linearly, making the silence itself a wake-up trigger<br>・This app uses a perceptual curve (logarithmic) to lower volume slowly and smoothly<br>・It doesn&#39;t go to zero, but rests on a subtle &quot;noise floor,&quot; removing the jarring drop into silence<br><br>◆ Customize to Your Sleep Pace<br>・No fixed presets; use a continuous slider to set fade duration from 1 to 30 minutes<br>・Adjust perfectly for nights you fall asleep fast or struggle to drift off<br>・Timer length is also customizable from 10 minutes to 2 hours<br><br>◆ On-Device Sound Generation<br>・Synthesizes Brown Noise, Gentle Rain, Warm Pads, and Pink Noise in real-time<br>・No loops means no seams and no repeating patterns<br>・Auto-quickens fade when screen turns off to aid sleep onset<br>・Continues playing with screen off, showing a gentle countdown on a dark, soothing interface<br><br>Fully offline. Works without internet connection.
