Best Free Sleep Apps in 2026: 5 Honest Picks
Disclosure: The team behind this guide makes Slo. The ranking below covers free app downloads on their documented free tiers; Slo’s free surface is the browser players and mixer at slonoise.com, so it opens the answer but takes no place in the ranking. Competitor details come from the official sources we checked on July 31, 2026. Free limits change, and no app in this list can guarantee better sleep.
Slo’s free browser players and mixer at slonoise.com are the simplest free way to get sleep sounds tonight: layer rain over brown noise, set a timer and install nothing. Among free sleep apps you download, White Noise Lite by TMSOFT is the strongest verified pick, Apple’s Background Sounds is the easiest built-in option on Apple devices, and BetterSleep, Calm and Noisli each offer a limited free tier around a larger paid library.
The full Slo library is not free; the browser players and mixer are. That is why Slo answers the question but does not take a slot in the download ranking below.
Free tiers at a glance
| Pick | What is available without payment | Platforms documented by the provider | Main catch |
|---|---|---|---|
| White Noise Lite | 50 standard-definition sounds, Mix Pad, recorder, alarms and background audio | iPhone/iPad, Android, Mac, Windows | Ad-supported; Full and Pro editions add features |
| Apple Background Sounds | Built-in ambient sounds, volume/EQ controls and a stop timer | iPhone, iPad, Mac | Apple devices only; no multi-layer mixer |
| BetterSleep Free | A portion of sounds and features after a free download | iOS, Android | Exact free catalog can vary in the app |
| Calm Free | Selected meditations, one Sleep Story and multiple background Scenes | iOS, Android, web | Much of the library is locked behind Premium |
| Noisli Free | 16 sounds, 1.5 hours daily streaming, three Playlists, five Favorites, simple timer | Desktop web; mobile apps also exist | Daily streaming limit; web feature set is desktop-oriented |
“Free” means different things in this list: ad-supported, built into the operating system, a partial catalog, or a daily time limit. We ranked each app on what its own documentation says the free tier includes, not on what a paid upgrade would add.
1. White Noise Lite by TMSOFT: best free sleep app overall
TMSOFT’s comparison table lists 50 standard-definition sounds, a Mix Pad, an advanced recorder, five alarms and background audio in White Noise Lite. The app shows ads, stock sounds play locally, and the companion White Noise Market adds community sounds. For a free download, that is a complete noise-machine workflow: mix a couple of sounds, set a fade timer, wake to an alarm.
Best for: People who want a real sleep-sound app with mixing, alarms and offline stock sounds at no cost.
Know before downloading: TMSOFT also sells Full and Pro editions as one-time purchases with different tools and sound quality. Compare its table before assuming Lite has everything.
2. Apple Background Sounds: best built-in option
Apple includes Background Sounds in supported versions of iOS, iPadOS and macOS. Its support page documents ambient soundscapes, volume and equalizer settings, and a stop timer. Nothing to install, no account, no ads. If a single steady sound at a comfortable level is all your bedroom needs, this may end the search.
Best for: Apple users who want one steady sound and basic controls without another app.
Know before using: It is not a layered mixer and does not offer the broader catalogs found in dedicated sleep apps.
3. BetterSleep Free: best free preview of a full sleep toolkit
BetterSleep says the app is free to download and that a substantial portion of its content and features is available without payment. The wider product includes a sound mixer, stories, meditations, a timer and sleep-tracking tools, so the free tier works as a preview of an all-in-one sleep app rather than a fixed catalog you can count on.
Best for: People deciding whether a broader sleep-content app is worth paying for.
Know before downloading: The provider directs users to the app for current offers. We do not treat its changing free catalog as equivalent to full access.
4. Calm Free: best free guided content
Calm’s help center says non-Premium users can access selected meditation tools, one named Sleep Story and many background Scenes that include nature sounds and ambient music. Locked items display a padlock. The free slice is small next to the Premium library of 300+ Sleep Stories, but it is real guided bedtime content at no cost, which nothing else on this list offers.
Best for: Someone who wants a taste of narrated wind-down content beside background audio.
Know before downloading: The full Sleep Stories and music libraries are Premium features, and pricing varies by region.
5. Noisli Free: best free browser mixer with a time limit
Noisli’s free web plan lists 16 sounds and 1.5 hours of streaming per day, plus three curated Playlists, up to five saved Favorites and a simple timer. The service lists iOS and Android apps, but notes the full web feature set is designed for desktop browsers. The daily cap is the problem for sleep: 1.5 hours may not cover falling asleep, let alone a full night.
Best for: Short wind-down sessions that fit inside the daily limit.
Know before signing up: Unlimited streaming and all 28 sounds require Pro under the current web plan.
What to check before relying on a free tier
- Ads and interruptions: An app can be no-cost and still show ads. Check whether they appear during playback.
- What is actually unlocked: A free download is not a free library. Open the app and count what plays before you build a routine around it.
- Timer behavior: A fade-out timer is different from an alarm. Test the control before bedtime.
- Streaming limits: A daily cap that suits a work session can run out mid-night. Confirm the limit against how long you want sound playing.
If the free browser route appeals more than a download, start with the rain player or a ready-made mix and read how to create a sleep soundscape for a step-by-step setup. For the noise-focused version of this question, see best free white noise apps.
Frequently asked questions
Is there a completely free sleep app?
TMSOFT describes White Noise Lite as free and ad-supported, and Apple includes Background Sounds in supported devices at no extra cost. Most other sleep apps are free downloads with a limited free tier: BetterSleep and Calm unlock part of their libraries, and Noisli’s free web plan has a daily streaming limit.
Can I get free sleep sounds without installing an app?
Yes. Browser players can cover plain playback and a timer with no download or account. Slo’s browser players and mixer at slonoise.com are free; Noisli also runs in a browser with a daily limit on its free plan.
What do free sleep app tiers usually leave out?
Common limits are ads during use, a locked portion of the sound or story library, daily streaming caps and missing extras such as offline downloads. Check the current store listing or help pages, because free tiers change.
Do free sleep apps work as well as paid ones?
For steady background sound and a timer, a free tier or built-in option often covers the whole job. Paid tiers mainly add larger libraries, guided content and convenience features. No app, free or paid, can guarantee better sleep.
