### 2/5 — Not too great

*2023-02-16, version 2.1*

This app seems pretty useless. I can’t use it for most of my normal internet use. If I try to log on to a website, I can’t access saved passwords while on this browser. I worry that it might be stealing information.

### 2/5 — I agree with the previous

*2021-08-27, version 2.1*

Review, what’s the point of this app if I can’t use it across all my phone use😕😑🙁🤔

### 1/5 — Don’t buy

*2018-02-16*

What  awaits of money. Only works when on its web browser not your entire phone.
NOT HAPPY!

### 2/5 — Not what I wanted

*2017-04-24*

I'm bummed.  This app is only for web browsing and it crashed many times while I used it for the first time last night.  I'll hold out for an app that cuts out the blue light for the entire phone, which is really what we need and want.  If it wasn't for the crashing, I'd say it worked great for searching the web.

### 1/5 — ONLY for browsing internet

*2016-12-21*

I thought this was a blue light filter for the phone... turns out it is just a web browser app that also happens to be filtered. Waste of money!

### 2/5 — App

*2016-10-05*

Average, Waste of money

### 1/5 — Of Little Use

*2016-10-01*

I'm sorry I paid for this app, as it is limited to browsing...not helpful.

### 1/5 — Waste of money

*2016-07-05*

An absolutely worthless. If it actually worked it would be one thing since it doesn't I don't recommend it for anyone to purchase

### 5/5 — Works great for me!

*2016-06-29*

I think some people don't realize that this is a browser. It won't cut the brightness or blue light if you are using anything other than this browser. But the browser works just fine and the amount of blue light and the brightness are adjustable, which is a nice feature.  This app is great for when I stay up way too late reading random crap on Reddit instead of going to sleep.

### 1/5 — Is useless

*2016-06-10, version 1.8*

Doesnt work
