Sereni: Sleep & Focus Sounds

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

Pick a theme and press play. Ambient gives you five soothing noise colors: White, Pink, Brown, Green, and Deep. Life Sounds brings real recordings of Rain, a Fan, and the Ocean. Lo-Fi adds three original, mellow instrumental beats made for long study sessions. Every sound is set against its own peaceful painted 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.

• Three themes: Ambient, Life Sounds, and Lo-Fi, with a simple switcher at the top of the player
