Sereni: Sleep & Focus Sounds

New in 3.1: the Sereni+ home-screen widget — play, pause, and switch sounds without opening the app.

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.
