Best Nature Sounds Apps in 2026: 6 Picks Compared
Disclosure: Slo is our app, and we wrote this guide. Every fact below comes from each company’s own store listing, support pages or website, read on July 31, 2026. We did not run hands-on tests, listening panels or clinical trials, so nothing here ranks apps by sound quality or sleep results.
Slo is a nature sounds app for iPhone, Android and Mac with free browser players at slonoise.com, where you can audition rain, a river or a forest before installing anything and then layer them in the mixer with a separate volume for each. Rain Rain has the strongest free tier for rain, with 50+ sounds and no time limit. myNoise gives you the most control over what each part of a soundscape does. Portal adds video and spatial audio on Apple hardware. Calm folds nature scenes into a wider sleep library. Apple’s Background Sounds plays ocean or rain with nothing to install.
How we picked these six
Nature audio is easy to sell and hard to compare. Two apps can both promise “rain,” then deliver a thin loop in one and a twenty-minute recording in the other, and no listing tells you which is which. So we compared what companies document rather than what they imply.
Four things decided the list:
- Real recorded nature, not only synthetic noise. Each pick documents rain, water, wind, birds or a full outdoor location.
- Control over what plays. Layer volumes, timers, fade-outs and tone controls, as described in official documentation.
- Platforms we could verify. Taken from store listings and support pages, not from press coverage.
- A cost model the company states plainly. Free tier, one-time purchase or subscription.
We left out three tempting shortcuts. Star ratings are popularity, not audio quality, so a 4.8 average never moved a pick up. Marketing lines about deeper sleep or lower stress carry no weight here, because no app’s listing counts as evidence for a health outcome. And since we did no listening tests, we never claim one app’s rain “sounds better” than another’s.

1. Slo: best for building your own nature mix
Slo’s library runs from rain and rivers to forest birds, with the noise colors alongside them. The mixer gives every layer its own volume, so birdsong can sit quietly above a river and stay where you put it. Curated presets give you a starting point, and the browser players carry volume and timer controls without a download. Download paths cover iOS, Android and Mac.
Best for: Anyone who wants a specific scene, like rain over a low rumble, and wants to keep adjusting it.
Tradeoff: Pricing and paid entitlements change by store and region, so read the current listing rather than trusting a figure in any article, including this one. We also don’t claim the whole library is free.
2. Rain Rain: best rain and weather catalog
Rain Rain’s App Store listing documents over 100 endless sounds, with 50+ available free and no time limit on playback. The free tier already includes the mixer with per-sound volume, every fade-out timer option, a bedtime reminder, an oscillator that slowly varies volume, and Soften, which muffles high frequencies so rain sounds like it’s outside rather than on your head. Premium adds 60+ sounds and removes the banner ad after a seven-day trial. The listing’s popular sounds include Rain on a Tent, Forest Rain, Thunderstorm, Slow Stream and Ocean Waves.
Best for: Rain listeners who want many versions of it and a free tier that stays usable.
Tradeoff: The US listing shows version 6.9.10 from January 2025, so the iOS app has gone a while without an update. Alongside Premium, the store also sells separate sound packs and single-sound tokens, which makes the total cost harder to read at a glance.
3. myNoise: best control over the sound itself
Stéphane Pigeon, a signal-processing engineer, has built and maintained myNoise since 2013, and it works differently from the rest. Each soundscape arrives as a set of sliders: Mediterranean Garden separates ocean waves, wind, cicadas and other layers, and White Noise & Co lets you shape a noise into whatever color suits your hearing. The catalog lists 300+ soundscapes, all built from real recordings with no generated audio. The website runs ad-free on donations, and the mobile app is free with one optional purchase for full access.
Best for: Listeners who want to fix what bothers them, like pulling the cicadas down and the surf up, instead of hunting for a better track.
Tradeoff: A screen of ten sliders takes more effort at midnight than one play button. Note also that paying for full access in the app is separate from a website donation, and myNoise rewrote its iOS app rather than updating the legacy one, so older purchases don’t carry across automatically. Our Slo and myNoise comparison covers the split in more detail.
4. Portal: best if you want to see the place
Portal records real locations in Iceland, Costa Rica, Scotland and elsewhere, then plays them back with spatial audio and window-like video at up to 12K. With AirPods Pro, AirPods Max, third or fourth generation AirPods, or Beats Fit Pro, the head-tracked audio holds the scene in place as you turn. The free tier gives you six portals with no ads or time limits, plus the sleep timer, focus timer, breathing exercises and sunrise alarm. Premium adds the rest of the library, along with Philips Hue, HomeKit and Nanoleaf lighting.
Best for: Apple users at a desk who want the visual half of a natural setting, not only the audio.
Tradeoff: There’s no Android app, and video means a screen stays lit. Portal’s own pages disagree on library size right now, listing 100+ on the App Store, 120+ on its site and “over 80” in the FAQ, and the FAQ states that free portals play at lower audio and visual quality than Premium ones. The US listing also shows version 3.8.3 from October 2024. See the Slo and Portal comparison for the full split.
5. Calm: best nature scenes inside a bigger sleep app
Calm’s nature audio comes as background Scenes and sleep sounds, including ocean waves, heavy rain and campfire, sitting beside Sleep Stories, meditations and music. A padlock icon marks Premium content, and Calm’s help center confirms that free users still get many Scenes, timed meditations, one breathing exercise and the Sleep Story Blue Gold. The main app runs on Apple and Android devices plus the web. Calm now ships three separate apps, and the newer Calm Sleep app is Apple-only and needs iOS 18 or later.
Best for: People who want narration and guided sessions as much as rain, in one subscription.
Tradeoff: You pick a Scene rather than building one, so you can’t sit birdsong under a stream and set each level. If sound is all you want, most of what you’d pay for goes unused. The Slo and Calm comparison lays out both feature sets.
6. Apple Background Sounds: best with nothing installed
Apple’s Background Sounds plays ocean, rain and noise presets on iPhone, iPad, Mac and Apple Vision Pro from Control Center or Accessibility settings, with iOS 15 as the floor. On iOS 26, iPadOS 26, visionOS 26 and macOS Tahoe, Apple adds a stop timer and an equalizer with Balance, Broad and Focused controls. Settings decide whether sound keeps playing when the device locks and how it behaves under other media, and a shortcut can start it when a Focus turns on.
Best for: A quiet office or a light sleeper who needs one steady sound and no new account.
Tradeoff: The preset list is short, there’s no layering, and nothing here works on Android or Windows.
Two kinds of nature audio
Compare a busy scene with a steady one
Forest Stream Awakening layers birds over moving water. Rain on the Roof stays flat and even. The difference matters more for sleep than the app you install.
Rain on the Roof
Two depths of rain gather above a quiet room, steadied by a neutral grey hush.
- Ambient Rain 50%
- Gentle Rain 34%
- Grey Noise 20%
How to choose in five minutes
Start from the room and the task, then pick the smallest app that covers it:
- You want rain and nothing else. Rain Rain’s free tier or Apple Background Sounds will do. Save your money.
- One sound is never quite right. Choose a mixer. Slo layers whole sounds; myNoise splits one soundscape into parts.
- You keep a screen in front of you anyway. Portal turns that screen into a window, provided you’re on Apple hardware.
- You also want a voice guiding you. Calm covers sound plus stories and meditation in one subscription.
- Your household runs on Android. That rules out Portal and Apple’s built-in option before you compare anything else.
Test whichever you choose for a week at low volume before paying. How to create a sleep soundscape walks through the setup, and how to use sound mixing covers balancing layers so one doesn’t swallow the other.
Want to try the mixer approach first? Slo’s browser players and presets run without a download, and the app is available for iOS, Android and Mac.
What a nature sounds app can and can’t do
Environmental noise can disturb sleep, and the World Health Organization’s guidance puts reducing the source first when that’s practical. Fixing a rattling window beats covering it. Where you can’t fix the source, a steady background may make sudden room noise less noticeable, though research on continuous sound for sleep remains thin and results vary between people.
None of these apps treats insomnia, tinnitus, anxiety or ADHD, whatever their marketing suggests. Persistent sleep trouble deserves a proper assessment, and CBT-I has far stronger clinical support than any sound-based self-help. Keep playback at the lowest comfortable level, keep speakers away from your pillow, and stop if the sound itself is what’s holding your attention. For what the research does support, read the benefits of nature sounds.
Frequently asked questions
What is the best nature sounds app?
It depends on how much control you want. Slo suits layered mixes, Rain Rain suits rain in every variety, myNoise suits shaping a soundscape element by element, Portal suits Apple users who want visuals, Calm suits guided content, and Apple Background Sounds suits basic playback with nothing installed.
Is there a good free nature sounds app?
Yes. Rain Rain gives you 50+ sounds, the mixer and every timer option free with a banner ad. myNoise’s website is free and ad-free, funded by donations. Apple Background Sounds costs nothing on supported devices, and Portal includes six free portals with no time limit.
Do nature sounds actually help you sleep?
They may help when noise is the problem, by reducing how sharply a car door or a hallway stands out. Evidence for continuous sound as a sleep aid remains limited and mixed, so treat it as a change to your room rather than a treatment. Some people sleep better in silence, which is worth testing for a few nights.
Which nature sound should I start with?
Steady rain or flowing water, since neither has sharp events to track. Birdsong and thunder add distinct sounds that can wake a light sleeper or interrupt reading, so they fit daytime better. If the labels confuse you, the guide to noise colors explains how rain differs from white and brown noise.
