Slo vs TMSOFT White Noise: Which App Fits? (2026)

Choose Slo if you want a curated library with ready-made presets you can test in the browser; choose TMSOFT White Noise if you want to record your own sounds, browse the 50,000+ White Noise Market or run it on Windows.

Disclosure: Slo is made by the team publishing this comparison. TMSOFT details come from the current official White Noise product and support pages, checked July 31, 2026. TMSOFT sells several editions, so a claim about “White Noise” may apply to Lite, Full, Pro, Market, or a desktop version—not all of them.

The short verdict

Choose Slo if you want a curated 151-sound library, ready-made browser presets, and a simple layer mixer you can try before installation. Choose TMSOFT White Noise if you want custom recording, offline local playback, Windows support, multiple alarms, or access to its 50,000+ community Market.

TMSOFT offers more tools and more community content. Slo offers a narrower, curated path with less catalogue browsing. The best fit depends on whether you value control and breadth or faster selection.

We omit exact edition prices. TMSOFT’s page publishes them, but store and regional amounts can change; the durable distinction is Lite versus one-time Full or Pro.

What Slo offers

Slo’s current product source describes 151 curated sounds for focus, sleep, and relaxation. Its website includes individual players with volume and timer controls, a multi-layer mixer, and curated presets. Download paths are available for iOS, Android, and Mac.

The library focuses on noise colors, nature, and atmospheric audio. Slo does not have a verified community upload market, custom recorder, offline mode, Windows app, or feature-parity claim across its app platforms.

What the TMSOFT White Noise family offers

TMSOFT’s current product page separates three editions:

Edition	Current official description
Lite	50 standard-definition sounds, recorder, five alarms, Mix Pad, background audio, and ads
Full	50 standard-definition sounds, recorder, Mix Pad, 20+ alarms, widgets and device integrations, with generator tools sold separately
Pro	50 high-definition stereo sounds, generator tools included, recorder, Mix Pad, 20+ alarms, and no ads

All three can add community content from White Noise Market. TMSOFT currently advertises more than 50,000 Market sounds, searchable by map, keyword, category, and recency. Users can record and loop their own audio and share recordings with the community.

The official page lists iPhone, iPad, Apple Watch, Apple TV, Android phones and tablets, Android TV, Mac, and Windows. It also says sounds play locally for offline use. TMSOFT’s support page warns that purchases are store- and platform-specific, so buying one version does not automatically grant a paid copy elsewhere.

The differences that matter

Curated library versus community scale

Slo’s 151 sounds are selected as a compact working library. TMSOFT starts with 50 edition-specific sounds and opens into a 50,000+ community catalogue. Market breadth helps when you want a particular fan, cabin, vehicle, or location. It also means more searching and variable user-uploaded material.

Lite, Full, and Pro are not interchangeable

Old comparisons often call White Noise a single low-cost app. That hides meaningful edition differences. Lite includes ads and fewer alarms; Full removes ads and has standard-definition sounds; Pro uses a separate 50-sound HD set and includes generator tools. Confirm the exact icon, edition, and platform before relying on a review.

Recording and generators

TMSOFT officially supports recording, looping, and sharing your own audio. Pro includes noise, tone, and binaural generator tools; Full lists those tools as an in-app purchase. Slo’s verified controls are built around selected sounds and volume mixing, not recording or signal generation.

Offline and platform coverage

TMSOFT states that sounds play locally and lists Windows along with Apple and Android platforms. Slo has a browser route and iOS, Android, and Mac downloads, but no verified offline or Windows claim. If either feature is essential, TMSOFT is the clearer first test.

Browser access

Slo’s core players, mixer, and presets work on the website. TMSOFT now offers full audio playback on the White Noise Market website, but the installed White Noise editions remain the route to the recorder, Mix Pad, alarms, and local playback. Browser playback and app functionality should not be treated as equivalent.

Which one should you choose?

Your priority	Better first test	Why
Curated mix with little browsing	Slo	Smaller library and ready-made presets
A specific niche recording	TMSOFT	50,000+ Market catalogue
Record your own fan or room	TMSOFT	Recorder and looping are official features
Windows desktop app	TMSOFT	Windows is explicitly supported
Test the full mixing idea in a browser	Slo	Mixer and presets are live without installation
Offline playback	TMSOFT	Official product page states local playback
Multiple alarms and generator tools	TMSOFT	Available by edition, strongest in Pro

More features do not prove better sleep. Keep any background quiet, preserve alarms, and compare it with silence. Our white noise and sleep guide explains the evidence limits.

Frequently asked questions

What is the difference between White Noise Lite, Full, and Pro?

TMSOFT says Lite has 50 SD sounds, ads, five alarms, recorder, and Mix Pad. Full removes ads and adds 20+ alarms and integrations. Pro has a separate 50-sound HD set and includes generator tools.

Does TMSOFT White Noise require a subscription?

Its current official page says no. It offers Lite and one-time Full or Pro purchases. A purchase may be platform-specific, so check the exact store.

Does White Noise Market really have 50,000 sounds?

TMSOFT’s current official product page advertises 50,000+ community sounds. These are separate from the 50 built-in sounds in each app edition.

Can both products work in a browser?

Slo offers its main players, mixer, and presets in the browser. TMSOFT offers Market web playback, but its recorder, Mix Pad, alarms, and offline use belong to installed editions.

Which is better for white, pink, or brown noise?

Both provide those basic colors. TMSOFT Pro adds generator tools; Slo offers immediate browser players and mix presets. Choose by control needs and comfort, not a promised sleep-stage effect.
