Sereni: Sleep & Focus Sounds

Sereni is the simplest way to play calming background noise for sleep, focus, and relaxation.

Choose from five soothing sounds — White, Pink, Brown, Green, and Deep noise — each set against a beautiful, peaceful background. Set a sleep timer to drift off and let Sereni stop on its own, with playback that keeps going in the background and full lock-screen controls.

Sereni's clean, modern design stays out of your way so you can focus on rest. No clutter, no sign-up — just press play.

Features:
• Five noise colors: White, Pink, Brown, Green, and Deep
• Choose a default sound to open to, or pick up where you left off
• Sleep timer that stops playback automatically
• Background playback with lock screen & Control Center controls
• Beautiful, calming backgrounds for every sound
• Light, Dark, and System appearance
• Designed for accessibility (VoiceOver & Dynamic Type)
• Sereni+ home-screen widget: play, pause, and switch sounds without opening the app

Want more? Sereni+ is a simple one-time purchase that removes all ads and unlocks the home-screen widget — a mini player with live artwork for whatever's playing.
