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😕😑🙁🤔 ### 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. ### 2/5 — App *2016-10-05* Average, Waste of money ### 4/5 — Great *2016-05-19, version 1.8* Great ### 3/5 — Does the job *2016-03-09* Works smoothly & doesn't crash, probably the best app of its type in the App Store. However, I really wish it would incorporate some kind of ad blocker. ### 4/5 — Great for nighttime web browsing *2016-01-23* Although the loading of pages is somewhat slower, I specifically got this app for its ability to cut the blue light glare at night. In that, it excels. I recommend this browser for anyone trying to reduce their overall blue light exposure (also get f.lux for your laptop!) ### 3/5 — Not for reading snooks! *2016-01-04* Hoping to find a filter for blue light while reading e-books I mistakenly downloaded this ap. Provides a filter for a web search only. ### 3/5 — Hm... *2015-10-24* App Keyboard auto-rotate is not working. Why does not it work? and Vertical lines appear on the keyboard in landscape mode. ### 1/5 — Useless app *2015-09-25, version 1.7* I downloaded this to cut down on blue light from my iPad so as to not interfere with sleep as search is showing that blue light does. I expected as anyone would that it would work on the entire iPad. In fact, it’s only for browsing the web. The screen doesn’t even useH the full iPad screen. It should be free for such a piece of junk and it costs $1.19. Don’t waste any money with it. ### 2/5 — Disappointing. *2015-08-16, version 1.7* It works within the app, but does not work throughout the phone and other apps. A pity. ### 1/5 — Junk! *2015-07-26, version 1.7* Total waste of $.99! ### 1/5 — Not too good *2015-07-06* I thought this ap would cut blue light from all my screens and not just when I hit the icon. Wish I could give it more stars... Would help if there were more directions... Sorry for bad review but it is a great idea. I like your graphics but you also need to correct the word "night" it almost made me not purchase the ap... But wanted to give benefit of the doubt. I just re read and now I understand what it meant that it only works on this ap. I didn't understand. Ok well it works nicely on your ap but I need it for my whole phone. I guess I will have to buy the screen for my phone that bulletproof executive mentions. Keep improving the ap and ganbatte! ## Most critical reviews (10 lowest-rated) ### 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! ### 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! ### 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 ### 1/5 — Is useless *2016-06-10, version 1.8* Doesnt work ### 1/5 — Rip off! *2016-01-04* This app is a waste of money and a trick. Do not buy! When you open the app, it redirects you your browser and that is the only place you can add a subtle amount of yellow tint. Not worth even 99 cents. ### 1/5 — Doesn't accept input from keyboard *2016-01-03, version 1.8* Waste of my time and money. Bought the app for night browsing that was healthier but can't browse as it didn't accept keyboard inputs from swiftkey unlike every other app I have used. Want a refund ### 1/5 — Waste of Money!!! *2015-12-31, version 1.8* This app Does Not cut the blue light AT All !!! Waste of money !! ### 1/5 — Not what I thought I was buying *2015-12-27, version 1.8* This app is only a web browser and does not dim/filter blue light from your phone in general. Unfortunately i did not understand this from the description before purchasing... ### 1/5 — Useless!! *2015-12-22, version 1.8* Useless app! Works only on browser. Should cut blue light on entire ipad. Very deceiving! ## Most praised reviews (10 highest-rated) ### 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. ### 5/5 — Very useful *2016-05-07* I like to use this app in the night time. Blue soothing layer makes screen less brighter. ### 5/5 — Good! *2016-04-16* Simple app to avoid eye strain! ### 5/5 — Works fine. *2016-01-01* I have no idea what the previous reviewer is complaining about. This is a browser that cuts blue light when you're browsing. It works fine. If you to cut blue light for everything, you need a different phone, because iPhones aren't designed to use such apps. ### 5/5 — Works for me *2015-10-05* Its been helping me sleep for a couple weeks now ### 5/5 — Love this app!! *2015-09-09, version 1.7* This app is only able to cut the blue light for surfing the web. Apple doesn't allow for a 3rd party app to affect globally so if you just want to surf at night this is great. Haven't had any issues with accessing YouTube or Facebook through is either. Don't know about other sites. ### 5/5 — Does what it needs to *2015-08-14* Low-light browsing. No muss, less fuss. ### 5/5 — Good but needs expanding *2015-06-23, version 1.7* It works amazingly for browsing, but it really needs updating so that you can choose to have it on using anything in your phone. Can't believe there isn't an app/function doing this yet, it makes a huge difference to your eye health... ### 5/5 — Very Useful *2014-11-21* Basically it is a web browser that you can control the brightness, blue, red and green light with. I enjoy it; I like being able to use it at night and not strain my eyes. It would be better if the iPhone itself allowed for such control, but until then we have this. ### 5/5 — Fabulous!!! 🌟🌟🌟🌟🌟 *2014-11-19* Exactly what I wanted!! Not only can you dim your browser but you can also make the colors warmer, which is SO nice. It also has other features such as history, tabs, etc. It only works for the browser of course, but that is because of iOS, not the app. Thank you to the creator for this app so I can browse at night!
