Features & Capabilities

Koala Browser - Sleep Better combines a fast browsing experience with sleep-enhancing features. It automatically filters blue light and adapts the display color temperature based on time of day to help you wind down at night and stay energized during the day. Note: Koala dimming effect only works while inside the app!

Key features include automatic color temperature adjustments tied to local time and sunrise/sunset, Darkness Boost for lower night brightness, multiple tabs, private browsing, history and bookmarks, sharing options, and support for multiple search engines. Downloads are supported too, and more features are coming soon.

User Reviews

Koala Browser reduces blue light and eye strain, and darkens pages for easier night-time reading, while remaining easy to use. However, filtering is browser- and Google-only, not system-wide, and customization is limited. Users frequently report intrusive ads and stability problems, with some noting the keyboard and other apps aren’t filtered. These issues limit its usefulness for broader device-wide blue-light protection.

Pros

Significantly reduces blue light and eye strain during nighttime browsing.
Darkens web pages for easier late-night reading.
Easy to use with a simple, user-friendly interface.
May help with headaches and sleep quality by reducing blue light for some users.

Cons

Blue light filtering is browser/app-specific and not system-wide; it only applies within Koala (and largely to Google).
Limited to Google/search within the browser; cannot change default search engine or start page.
Intrusive ads and pop-ups, including after paying for 'no ads' option.
Stability issues: occasionally crashes or won't open after updates.
Not effective across the entire device; keyboard and other apps may not be filtered.

Keyboard still not yellow

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.
