The Best Free Sleep Sounds App: Rain, White Noise & Ocean (2026)

The Short Answer

You can fall asleep to a full mix of sleep sounds for free — rain, ocean waves, a crackling campfire, wind, a forest at night, crickets, distant thunder, and white/pink/brown noise — layered into your own blend, with a sleep timer that fades everything out and keeps playing after you lock your phone. No subscription.

The catch is that the popular sleep apps charge for it: Calm and BetterSleep both put their sound libraries behind a monthly (or yearly) subscription. The free way that just works in 2026 is Trending Music, which now includes a built-in Sleep Sounds mixer.

Why Sleep Sound Apps Usually Cost Money

"Play rain while I fall asleep" sounds like it should be free — and the raw sounds are — but the apps built around them are subscription businesses:

- Calm — the sleep library and Sleep Stories are Premium (roughly $69.99/yr). - BetterSleep / Relax Melodies — mixing more than a couple of sounds, and most of the catalog, wants a subscription. - Endel — subscription-only.

So the simple thing you actually want — a few nature sounds mixed together with a timer — ends up behind the same monthly fee as everything else.

How to Use It (Under a Minute)

1. Download Trending Music free on your iPhone: https://apps.apple.com/us/app/trending-music-player/id1139055265 2. Open Settings → Sleep Sounds (in the Tools section). 3. Tap any sound to turn it on, then use its slider to set the level. Layer as many as you like — rain + brown noise + a little thunder makes a great storm. 4. Tap a preset (Rainy Night, Ocean Calm, Fireside, Forest, Deep Sleep) for an instant mix. 5. Set the Sleep timer (15–90 minutes) and put the phone down — the mix gently fades out and stops on its own, and keeps playing while your screen is off.

That's it — no trial countdown, no paywall on the sounds.

The Sounds You Get

A full mixer, not just one loop:

- Rain — steady, even rainfall - Ocean Waves — slow, swelling surf - Campfire — a warm crackle - Wind — gusting through the trees - Forest Birds and Night Crickets — the outdoors after dark - Thunder — occasional distant rumbles rolled over the rain - White, Pink & Brown noise — generated on your device, so they work with no internet at all

Blend any of them, save your favorite mix, and it's waiting for you the next night.

Fall Asleep to Your Music, Too

Sleep sounds play alongside your music, so you can drift off to a quiet playlist under a layer of rain. And because it's a full music app, the same free download also gives you on-demand songs, music videos and synced lyrics, live radio and podcasts, and offline downloads for nights the Wi-Fi drops.

There's even a music alarm clock to wake up to any song — so the app carries you from lights-out to morning.

Is It Really Free?

Yes — the Sleep Sounds mixer, the presets, the sleep timer, and background playback are all free, with no trial countdown and no subscription. (There's an optional Premium tier at $5.99/mo — for ad-free listening, AI DJ and more — but the sleep sounds themselves aren't behind it.)

Compare that to $69.99/yr for a dedicated sleep app that does less. Set it up before bed tonight: https://apps.apple.com/us/app/trending-music-player/id1139055265
