## Koala Browser Description
Sleep better with Koala™! A faster web browser with downloads, 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: Koala dimming effect only works while inside the app!)

The Koala™ 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! Koala™ makes the color of your iDevice display adapt to the time of day, warm at night and like sunlight during the day. All automatically!

FEATURES
* Automatically adjust the color temperature depending on your local time and sunset/sunrise times
* DOWNLOAD and view files!
* Darkness Boost for lower brightness during the night
* Multiple browser tabs
* Private browsing
* History and Bookmarks
* Sharing to Twitter, Facebook, Email, Text, WhatsApp etc
* Select search engine (Google, Yahoo!, Bing, DuckDuckGo)
* More features coming soon!

## Koala Browser Reviews in United States

### ****- "Works! Not perfect"
Keyboard still not yellow
-- Dre86., 2023-08-31

### *---- "It’s a browser app"
I was hoping an actual full system blue light filter, where you can hop between apps. This is just a blue light filtered browser, outside of the browser it’s same light device.
-- how it is123456789, 2022-10-12

### *---- "Google only"
Only works with Google. Does not work beyond that.
-- youre daddyo, 2021-05-14

### **--- "I can’t delete my search history."
Great app. Very easy on eyes.  No ads. Easy to use. Only works with google. Pisses me off I can’t delete my search history!  I may end up just deleting the app.
-- tony12toes, 2021-03-09

### *---- "Remove"
I want to remove this app
-- cherrypepper23, 2021-01-29

### ***** "Saved my eyes"
So far, in the two years I’ve been using Koala, it’s darkened every webpage I’ve visited. This allows me to view pages late at night without pain. The app works flawlessly for me.
-- NW1234, 2021-01-28

### *---- "RIPOFF"
CHANGE SEARCH ENGINE AND YOU STILL GET GOOGLE WHICH I AVOID AT ALL COSTS. THEY NEED TO ALLOW YOU TO CHANGE THE START PAGE. WASTE OF 2.99. DO NOT BOTHER USING THIS
-- coreman2, 2020-08-24

### ***-- "Not bad"
Great but shame it’s only google use
-- CorAali ( ͡° ͜ʖ ͡°), 2020-07-12

### ***-- "Good App"
This app blocks blue light which protects your eye. The only thing is it is only for Google. So if you want this app to block blue light from other apps, it can’t do that. I’ll rate it 3 stars for blocking only Google. Everything is good except the fact it doesn’t do it for anything else.

{Tip: If you want a blue light protecting, go to settings and go to displays & brightness. Click night shift and turn it on. Now you have a blue light protector without downloading anything! Thanks Apple for including this! You can also schedule when to turn on night shift}
-- Kelly🐇🤍, 2020-06-16

### ****- "."
It shuts down while I’ve used it a few times, but otherwise helpful!
-- Eotzelberger, 2020-06-10
