### 2/5 — Pointless

*2023-10-07, version 7.4*

When I got this I found that on my phone it only works when you’re in the app.I’m not sure if it’s meant to do that but I found that quite pointless.Also in settings you go to display and brightness then click Night Shift and you can do the exact same thing as the app would do so please don’t get this. You don’t need it!

### 4/5 — Works! Not perfect

*2023-08-31, version 7.4*

Keyboard still not yellow

### 4/5 — No está mal, pero…

*2022-09-02, version 7.4*

El filtro naranja tiene mejor intensidad que el del mismo Night Shift, mas queda claro que la atención de las personas no sólo está en el navegador, sino en las redes y en general.

### 2/5 — I can’t delete my search history.

*2021-03-09, version 7.4*

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.

### 3/5 — Not bad

*2020-07-12, version 7.4*

Great but shame it’s only google use

### 3/5 — Good App

*2020-06-16, version 7.3*

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}

### 4/5 — .

*2020-06-10, version 7.3*

It shuts down while I’ve used it a few times, but otherwise helpful!

### 1/5 — Too many ads

*2020-05-22, version 7.3*

Each time I opened it there would be a ad

### 1/5 — One of the worst apps

*2020-05-18*

Why can’t they ever make it easy to operate and work as if shown in the picture

### 1/5 — Buggy

*2020-05-11, version 7.3*

It is buggy and ads are almost impossible to close and the actual app isn’t even worth using, just use night mode

### 1/5 — Does work for all apps

*2020-05-03, version 7.3*

Trash

### 4/5 — Maybe

*2020-04-21, version 7.3*

Koala although may be great but I really don’t see why you can’t just use chrome, it is the EXACT same thing no diff. It is chrome with a different name, Koala.

### 1/5 — Don't waste your time.

*2020-04-12, version 7.3*

Garbage app, doesn't work.

### 1/5 — Hgcbn

*2020-02-13, version 7.3*

Muy mala

### 1/5 — Pratique

*2020-01-30, version 7.3*

Totalement inutile

### 1/5 — Arnaque

*2020-01-11, version 7.3*

C’est pas app c’est une arnaque c’est une pub qui t’envoie pour acheter des lunettes

### 1/5 — Horrível

*2020-01-10, version 7.3*

Eu pensei que ele fosse um filtro de luz mas é um navegador, e péssimo!
Por favor arrumem isso

### 2/5 — Download something else

*2019-12-29, version 7.3*

This app does not work for your entire phone. This orange light/blue light is only for browsing google, not if you want to write an email or stream videos! Waste of download

### 1/5 — 아니 광고가...

*2023-11-26, version 7.4*

새로고침 했더니 광고가... 별 1개도 아깝다.

### 1/5 — ужасный

*2023-04-18, version 7.4*

одни минусы 
1 разные цвета нет естественного 
2 горите вы что он бесплатный а сами снимайте 75 рублей
вы ужасные лучше удалите и пиределайти

### 1/5 — It’s a browser app

*2022-10-12, version 7.4*

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.

### 1/5 — Google only

*2021-05-14, version 7.4*

Only works with Google. Does not work beyond that.

### 1/5 — Pretty useless

*2021-02-02, version 7.4*

It’s a bit pointless I thought it was for the whole thing but it’s for a browser. Good concept but useless on just a browser

### 1/5 — Remove

*2021-01-29, version 7.4*

I want to remove this app

### 1/5 — Seriously adds with this 😡

*2020-10-21, version 7.4*

Downloaded to help me while suffering one of my migraines, my volume was switched off it’s 3 am in the morning and I was unable to sleep, out of no where a a lot app popped up on full volume almost woke my partner, never again, you can only use it for browsing internet aswell, and it’s its own built in internet, I will have to find something else as the iPhone settings on the lowest is still too bright

### 1/5 — RIPOFF

*2020-08-24, version 7.4*

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

### 1/5 — Sólo funciona dentro de la app

*2020-07-04, version 7.3*

Una vez que cierras o cambias de aplicación se desactiva el cambio de luz👎

### 1/5 — Maybe a glitch

*2020-06-03, version 7.3*

The app for me on the apple iPad just brings me to google and doesn't do anything. I don't know if it's a glitch or what.

### 5/5 — Saved my eyes

*2021-01-28, version 7.4*

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.

### 5/5 — Good app but should be usable for everything on the phone

*2020-12-07, version 7.4*

When where we will be able ton use the app on the entire photo and not only for the browser

### 5/5 — Good with iPad

*2019-12-08, version 7.3*

This app help me to read web pages under the dark a lot

### 5/5 — It’s great

*2019-11-23, version 7.3*

It’s a great app to use especially at night when your eyes are most sensitive to blue light
I would highly recommend

### 5/5 — Like that blue light ..

*2019-05-20, version 7.3*

Nice,

### 5/5 — Top mais urgent que cela soit sur tout l’appareil !

*2019-03-15, version 7.2*

Dommage que l’application ne fonce que dans le navigateur. Androïd est sacrément en avance sur ce coup là.

### 5/5 — Géniale

*2019-02-24, version 7.1*

GÉNIALE comme idée mais à retravaillé... Manque de généralités

### 5/5 — Simple but useful

*2019-01-08, version 7.1*

While you’re browsing it keeps the blue light out. Hoping there will be away soon to do it for the entire phone but this helps for now

### 5/5 — Très bonne idée

*2018-07-23, version 7.1*

Excellente initiative, un filtre visuel de ce genre devrait être beaucoup plus présent sur les applications iPhone.

### 5/5 — excelente

*2018-01-09, version 7.1*

La verdad que esta aplicación es fantástica para poder navegar de noche o a oscuras sin dañarte la vista y pues la verdad es que si recomiendo que se la descarguen
