These are six products that replace distinct parts of Endel: Brain.fm for functional focus audio, NEDIO for coding sprints, Portal for immersive nature, Dark Noise for manual mixes, Pzizz for sleep, and myNoise for free sound shaping.
By Timur Khaziev, founder of NEDIO. NEDIO is our product. We apply the same criteria to every option and link to each vendor’s current pricing. Screenshots were captured in September 2026.
Start with the part of Endel you actually use. Brain.fm is the closest focus-first substitute; Portal replaces the immersive atmosphere; Pzizz specializes in sleep; NEDIO structures coding sessions; Dark Noise and myNoise give you direct control over sound.

USD prices and public plan details checked October 9, 2026. Endel pricing varies by platform and region. Vendor terms can change; confirm them at Endel, Brain.fm, NEDIO, Portal, Dark Noise, Pzizz, and myNoise.
Endel does several jobs, so a single winner is the wrong question. Pick the job, the device, and the budget. The picker filters the facts in the table above and shows up to three options to look at first.
First look · built for this
Option 2 · partial fit
Option 3 · partial fit
Left out for this device or budget: Pzizz (not available on your device).
This filters the comparison facts on this page by what each product covers, where it runs and what it costs. It does not measure how well any of them works, and nothing you choose is sent anywhere.
Before switching, check what Endel itself lists on its site (October 9, 2026). Several of these are the reasons people use it, and most of the alternatives do not try to match them.
Focus, Relax, Sleep, and Activity, with an ADHD mode shown in its navigation.
Time of day, weather, heart rate, and location. The Apple Watch app also uses light and other biometric data.
iOS, Android, Apple Watch, Mac, Windows, web, Apple TV, Fire TV, and Alexa devices.
None of the six alternatives advertises automatic adaptation to those inputs. If that is the part you value, the honest answer may be to stay. If you only use one mode, an alternative can cover it for less, or for free.
We checked each vendor’s public product and pricing pages on October 9, 2026. Endel covers several jobs, so we compared how each service handles focus, relaxation, sleep, personalization, sound control, free access, and supported devices. The screenshots are our captures of public vendor pages. This is a comparison of documented features, not a hands-on test of each app and not a study of health or concentration outcomes.
We identify whether an app replaces adaptive focus audio, relaxation, sleep, movement, or ambient masking.
A short trial and an ongoing free plan are listed separately, with daily limits where vendors publish them.
We compare automatic adaptation with manual mixing, then check web, mobile, desktop, and wearable access.
There is no exact clone of Endel’s context-aware engine. The strongest replacement depends on whether you care most about general focus, a structured coding session, natural environments, sleep, or sound control.
The order follows closeness to Endel’s focus use, not a quality score. NEDIO is our product and sits second because it is the developer-specific option. If you do not code in timed blocks, start with the picker above and ignore the rank numbers.
People who want engineered focus music with clear activity modes instead of an adaptive all-day soundscape.
Developers who want focus audio tied to a clear work block, a timer, and a short record of what they finished.
People who use Endel for atmosphere, relaxation, or sleep and want real natural environments with rich visuals.
Apple users who want a fast ambient-noise player, custom mixes, offline playback, widgets, and Shortcuts support.
People who primarily use Endel at bedtime or for power naps and want audio sessions built around those outcomes.
Building a precise sound field, masking distracting noise, or exploring a large browser-based library without another subscription.
These are the two closest audio-first products in the comparison. Endel emphasizes personalized soundscapes that adapt across context and devices. Brain.fm emphasizes functional music for named activities.
Choose Endel when adaptation across focus, relaxation, sleep, movement, and devices is the central value.
Choose Brain.fm when you prefer activity-labelled functional music and already have a work-session routine.
For a broader view of the same audio-first category, see the Brain.fm alternatives guide.
Five picks offer a lasting free path. Compare what remains available after a trial ends and whether the free experience covers your main Endel use case.
Open Access includes free portals with no ads or time limits, plus focus, sleep, meditation, and breathing tools.
30 minutes of audio without an account or 60 minutes with a free account. A sprint starts with audio, so using it up also stops new sprints until it resets.
A free, ad-free selection of detailed generators with manual frequency controls in the browser.
Pzizz keeps Classic content free. Dark Noise is free to download, with some sounds and advanced features in Pro.
NEDIO makes sense when your main problem is starting and finishing a coding block. It combines a sprint timer, instrumental stations, and a short close-out in one browser tab.
NEDIO is included in the ranking as the developer-specific option. Brain.fm is closer for general functional audio, Portal for atmosphere, Pzizz for sleep, and myNoise or Dark Noise for manual ambient control.
You can test NEDIO on a real task with 30 minutes of audio without an account, or 60 minutes per day when signed in. For a direct workflow comparison, read Endel vs NEDIO.
Feature lists cannot tell you whether a replacement works for your ears and your day. Test one candidate on its free path or trial, using real work or real nights.
Five sessions will not prove anything about focus. They will tell you whether you can live without what the alternative lacks. For a longer log of audio and focus ratings, see the two-week audio log.
Checked on October 9, 2026: Brain.fm, Portal, and Pzizz pricing pages, myNoise support options, and the Endel, Dark Noise, Pzizz, and myNoise home pages for platforms and features. Dark Noise and Endel do not list prices on the pages we read, so the page says so.
Not done: we did not run listening tests of every app or measure focus, sleep, or any health outcome. We found no study that tests these six apps on developers' work output. Treat the comparison as documented features plus a way to run your own trial.
Interest: NEDIO is our product. We apply the same criteria to every option and link to each vendor's current pricing. Vendor terms change, so confirm before you pay.
Brain.fm is the closest alternative when your main use case is focus. It offers functional audio for activities such as deep work and learning. Portal is closer to Endel’s immersive atmosphere, while Pzizz is the stronger substitute for sleep and power naps.
Yes. Portal Open Access includes free portals with no ads or time limits. myNoise offers a free, ad-free selection of adjustable generators. NEDIO includes 30 minutes of audio without an account or 60 minutes per day when signed in. Dark Noise is free to download, and Pzizz keeps its Classic content available at no charge.
Yes, but the products structure audio differently. Endel generates personalized soundscapes that adapt across the day and across devices. Brain.fm provides functional music grouped by activities. Brain.fm is the closest alternative in this list when engineered focus audio is the main requirement.
Pzizz is the most sleep-specific option in this comparison. Its Sleep and Nap modules combine changing music, sound effects, and optional voice narration. Portal is a better choice when you want natural environments and spatial audio for both sleep and daytime relaxation.
Portal and Dark Noise are both designed for iPhone, iPad, and Mac. Choose Portal for recorded natural environments, visuals, and spatial audio. Choose Dark Noise for offline playback, custom mixes, shortcuts, widgets, and direct control over individual ambient sounds.
NEDIO can replace Endel when your main use case is a bounded coding session. It combines instrumental audio with a sprint timer and a session close-out. It does not reproduce Endel’s adaptive sound engine or its broader relaxation, sleep, and movement modes.
Endel’s site says its soundscapes adapt to time of day, weather, heart rate, and location, and it lists Focus, Relax, Sleep, Activity, and ADHD modes across phones, watches, desktop, web, TV, and Alexa. None of the six alternatives here advertises that kind of automatic adaptation. If it is what you value, keep Endel. If you mainly want one kind of audio, one of the alternatives can cover it.
We found no study that tests these six apps on developers’ work output, and this page does not measure it. For what controlled studies do show about noise, lyrics, and background music, see the research page on best music for coding and the guide for ADHD developers.
As of October 9, 2026, Brain.fm lists $14.99 per month or $99.99 per year, Portal lists $2.99 per month, $29.99 per year, or $99.99 lifetime, and Pzizz Pro lists $7.99 per month or $49.99 per year. Dark Noise publishes its current Pro price in the App Store. myNoise can be used free, with optional support unlocking website privileges.
