## What is Slumber Wave?

Need brown noise to sleep, but not another app that locks it after an hour? Slumber Wave gives you 33 sounds free, with no ads and no time limit.

Layer brown noise with rain on a window or ocean waves, set each volume on its own slider, and let the sleep timer switch it off once you are asleep. Premium unlocks all 106 sounds and all 5 mixer layers.

WHAT YOU GET

- 106 sounds in 10 categories: Rain, Water, Ocean, White Noise, Brown Noise, Pink Noise, Hz Frequencies, Binaural Beats, Household (fans, dryers, heaters) and Transportation
- 33 of them free, with no ads and no time limit on listening
- A mixer with up to 5 layers and its own volume slider for each one. The first 2 layers are free
- Save a mix and bring it back with one tap. The free plan keeps 1 saved mix, Premium keeps as many as you like
- Sleep timer: 5, 10 or 20 minutes on the free plan; 30, 45, 60 minutes or endless with Premium
- Change the timer while a sound is playing and the sound keeps going, with no restart
- Background playback and lock screen controls
- The screen dims itself, so it does not light up your room
- Sign in and your favorites and mixes follow you to a new phone, or start as a guest and create an account later in Profile
- Seven app languages: English, Turkish, German, Spanish, Swedish, Chinese and Azerbaijani

MORNING SUMMARY

After a night with a sound playing, Morning Summary shows when the sound started and stopped, what played, and an estimate of how long it took you to fall asleep, based on your phone's motion sensor. On iPhone it can also read your sleep from Apple Health. Nothing is recorded when no sound is playing. Sleep times are estimates, not a medical measurement.

PREMIUM REWARDS

Rewards need an account (creating one costs nothing), and each one can be claimed once.

- Play Slumber Wave 7 nights in a row and claim a week of Premium
- Share one of your mixes once and get 3 days of Premium

GOOD TO KNOW

Slumber Wave streams its sounds, so it needs an internet connection to play.

SUBSCRIPTION

I originally downloaded this for sleep, but now I use it while working too. Mixing forest sounds with white noise helps me focus without distracting music. The app is clean, fast, and really easy to use.

### 5/5 — Exactly what I was looking for!

*2026-03-15*

I heard this new app is being built entirely around use feedback, so i decided to give it a try. Even though it’s still in its early stages, the current features are already super satisfying. Highly recommend getting in early!

**Developer response:** Thank you for your feedback, we are up to date.
