Disclosure: The team behind this guide makes Slo. We checked official sources on July 31, 2026. Noisli currently lists both iOS and Android apps. Older articles wrongly say it ended Android support.
Slo is the closest Noisli alternative: the same build-your-own-mix idea, free to try in browser players and a mixer at slonoise.com, with apps for iPhone, Android and Mac and an individual volume on every layer. White Noise by TMSOFT adds recording, alarms and broad device support; Dark Noise is the Apple-native choice; BetterSleep adds a larger sleep toolkit; Brain.fm replaces nature sounds with functional music; and Endel removes manual mixing in favor of adaptive soundscapes.
Noisli’s current web Pro plan lists 28 mixable sounds, unlimited streaming, Playlists, Favorites, an advanced Timer, a Markdown editor, Oscillation and Shuffle. Its Free plan has 16 sounds and 1.5 hours of daily streaming. The company also lists iOS and Android apps, while noting that the complete web feature set is designed for modern desktop browsers.
That means platform loss is not the main reason to switch in 2026. Better reasons include wanting more sounds, a native Mac workflow, recording and alarms, guided sleep content, functional music, or adaptive audio.
| Alternative | Best for | Audio approach | Verified platforms | How it differs from Noisli |
|---|---|---|---|---|
| Slo | Simple layered ambience | Manual layer volumes | iOS, Android, Mac; browser tools | A curated sound library and a dedicated mixer |
| White Noise by TMSOFT | Noise-machine controls | Mix Pad, recordings, playlists | iPhone/iPad, Android, Mac, Windows and more | Adds alarms, local stock playback and recording |
| Dark Noise | Apple shortcuts and widgets | Sounds and custom mixes | iPhone, iPad, Mac | Deeper Apple system controls |
| BetterSleep | A broader bedtime toolkit | Large mixer plus guided content | iOS, Android | Adds stories, meditations and tracking |
| Brain.fm | Focus music | Purpose-built functional music | Web, iOS, Android, desktop | Not an ambient layer mixer |
| Endel | Low-decision adaptive sound | Real-time generated soundscapes | iOS, Android, Mac, web and more | Adapts rather than asking you to build a mix |
Slo uses the same basic interaction that attracts people to Noisli: select ambient sounds, set each volume and let the mix run. Its curated library covers noise colors, nature and atmospheric audio. Browser players include volume and timer controls, and downloads cover iOS, Android and Mac.
Choose it if: You want a conventional mixer with a larger documented library and native app download paths on those platforms.
Skip it if: You want Noisli’s built-in writing editor or its specific work-session statistics.
TMSOFT lists 50 bundled sounds, Mix Pad, timers and alarms, recording, playlists, local stock playback and White Noise Market access. The product family spans mobile, desktop, watches and TV devices.
Choose it if: Recording your own loops, offline stock sounds or alarms matter.
Skip it if: You mainly want a minimal browser workspace.
Dark Noise documents 50 sounds, custom mixes, widgets, keyboard shortcuts, a mini player and menu-bar support on Mac. Its mix editor provides separate volume controls.
Choose it if: Your workflow stays on Apple hardware and you want fast system access.
Skip it if: Android access is required.
BetterSleep documents a mixer with more than 500 sounds and melodies, plus stories, meditations, timers, reminders, tracking and a sleep recorder. Its mobile apps run on iOS and Android.
Choose it if: Sound is one part of a broader bedtime routine.
Skip it if: Noisli’s small work-oriented interface is exactly what you liked.
Brain.fm offers task-oriented music modes, intensity controls and timers across web, iOS, Android and desktop. It is not a sound mixer, which makes it a genuine alternative rather than a close substitute.
Choose it if: You used Noisli mainly to concentrate and prefer music-shaped audio.
Skip it if: You want rain, fans and noise colors that you can combine yourself.
Endel generates soundscapes that can respond to time, weather, light, movement or heart rate, depending on device and permissions. Its official platform list includes iOS, Android, Mac, web and several other devices.
Choose it if: Selecting and balancing sounds is unwanted work.
Skip it if: A stable, repeatable mix matters more than adaptation.
Noisli-style presets
Try two ready-made combinations and change one layer at a time. The useful mix is the one you stop noticing.
A low noise floor, spacious focus ambience, and barely audible keys for a settled desk.
A centered noise bed and flowing water for sustained desk work.
Yes. Noisli’s official apps page currently lists an Android app as well as iOS. That current listing supersedes older articles that say otherwise.
Its current Free web plan includes 16 sounds and 1.5 hours of streaming per day. Pro raises the sound count to 28 and removes the daily streaming limit. Check current mobile terms in the relevant store.
Slo is closest in basic mixer interaction. TMSOFT is closer to a full noise machine; Dark Noise emphasizes Apple controls; Brain.fm and Endel use different audio models.
