## What is Sloths Browser?

Sleep better with Sloth A faster web browser, that improves the quality of your sleep! 

Research has demonstrated that nighttime light exposure suppresses the production of melatonin, the major hormone that controls sleep and wake cycles. The "blue", short-wavelength light is the most melatonin-suppressive, and is also emitted by devices such as televisions, computer screens, and cellphones.

(Note: Sloth dimming effect only works while inside the app!)

The Sloth Web Browser filters out the blue light to create a healthy, energizing sleep cycle. It is the first web browser that cares about your sleep quality! Sloth makes the color of your iDevice display adapt to the time of day, warm at night and like sunlight during the day. All automatically!

### 5/5 — Sloths Brower

*2026-04-10, version 3.8*

Freeman

### 5/5 — Awesome

*2024-11-13, version 3.8*

Much better for your eyes, just like a book

### 1/5 — 무료 아닌가요?

*2024-11-01, version 3.8*

무료로 알고 받았는데, 유료인가요? 결제 취소해주시고, 구매 내역 삭제해주세요. 앱 삭제했는데, 구매 내역에서 삭제가 안됩니다.

### 5/5 — 간절히 찾고 있던 앱입니다

*2024-08-29, version 3.8*

블루라이트 차단어플 최고에요👍🏻

### 5/5 — Too many ads

*2024-02-16, version 3.6*

Too many ads

### 2/5 — Too many ads

*2023-10-05, version 3.6*

Adds keep popping up every other second when I try to change the settings. Also, doesn’t cover the keyboard, so this is kind of pointless if I’m trying to use it at night to reduce blue light. iOS in general is so disappointing for apps it’s obvious how they try to control everything and can’t allow us to have diversity. Not a single app for an all over screen dimmer, not a single one. Everything is browser-based. Thats ridiculous.
Updated: just deleted it after five minutes. The pop-up ads make it unusable.

### 3/5 — Alright app

*2023-07-24, version 3.6*

Wish for less ads or would be 5

### 1/5 — Nightmare of ads with bad ux to navigate them

*2023-04-23*

Hah

### 1/5 — Full page Ads every minute or so.

*2023-02-02*

Only uses blue light filter for browser.
Full page ads, sometimes with video and audio, interrupts browsing to make it the most frustrating experience. Deleted.

### 2/5 — Needs improvement but lots of potential

*2022-08-20, version 3.2*

I do not recommend. Flashes an ad every 30 seconds which is not only annoying but is not even in night mode so there’s no escaping the blue light. Also blue light filter doesn’t cover things like youtube videos when you full screen them or the keyboard but idk how hard that would be to fix so not a big deal. However the browser does not work fully correct on every website, often displaying an outdated or nonupdated version of that site, which is why I am deleting the app. I hope this review helps the developer!
