Koala Browser - Sleep Better and Browse the Web

By AppRebel, Inc.

This app is only available on the App Store for iOS devices.


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!

Helps so much

I have a really bad habit of going on my phone before I sleep, this helps so much because now i can do that and still fall asleep quickly, only works on the app sadly, but the app is just like safari and has a lot of helpful features and settings along with being very easy to navigate

Great Concept, Great App

I got this app for my iPod Touch 5 since night shift mode is not available on it. The night mode works decently, however the settings menu needs a bit of tweaking in my opinion. It was a little confusing for me but I figured it out eventually. Overall a great browser, I do recommend it.

Cool but there are better alternatives

If you scroll up the menu from the bottom of the screen, there is something called "Nightshift". If you enable that, your iPhone/iPad will block blue light for your entire device and not just a browser.
