How to Use Only ZZZs

Simple steps for a peaceful night’s sleep

Only ZZZs was designed to be the simplest sleep app possible.
There are no menus, no settings, and no distractions.

Just one sound and one button.

Step-by-step instructions

1. Open the OnlyZZZs app

Launch the app on your phone.
You’ll see a calm ocean background and a single control in the centre of the screen.

2. Press the PLAY button

Tap the PLAY icon.

  • The ocean waves will begin immediately.
  • The sound will loop continuously.
  • The timer will start counting how long it has been playing.

3. Place your phone beside your bed

You can:

  • Leave the phone on your bedside table
  • Use headphones
  • Connect to a speaker

For best results, keep the volume at a comfortable, gentle level.

4. Turn off the screen

Once the sound is playing:

  • Lock your phone
  • Turn the screen off
  • Place the phone on charge if possible

The ocean sound will continue playing while you sleep.

5. Press STOP in the morning

When you wake up:

  • Unlock your phone
  • Open the app
  • Tap the STOP icon

The sound will stop and the timer will reset.

Tips for the best experience

Keep the volume gentle

The sound should be:

  • Calm
  • Soft
  • Comfortable

It should blend into the background, not dominate the room.

Use it every night

Your brain responds well to consistency.

Using the same sound each night helps:

  • Build a sleep routine
  • Reduce mental stimulation
  • Improve sleep patterns over time

Charge your phone overnight

For uninterrupted playback:

  • Plug your phone in before sleeping
  • This ensures the app can run all night

Disable battery optimisation (if needed)

Some phones stop background apps to save power.

If the sound stops during the night:

  1. Open your phone settings
  2. Go to Battery or App power management
  3. Find OnlyZZZs
  4. Set it to Unrestricted or Not optimised

That’s all there is to it

OnlyZZZs was built around one idea:

Sleep should be simple.

  • No ads.
  • No tracking.
  • No subscriptions.
  • No distractions.

Just:

  • Press PLAY
  • Close your eyes
  • Let the ocean do the rest
