I didn’t know, had no way to know, that by clicking on this app that it would 1. Not work at ALL and 2. Charge me $29.99 and 3. Create a SUBSCRIPTION that you have to manually go in and cancel. Would be easy to miss. What an honor to pay money for a nonfunctioning app and still no blocked blue light. It’s just a con. ### 1/5 — Only filters within App itself *2025-01-15, version 1.7.2* Apps it is not possible for the Blue Light Filter to filter another application on iOS (due to how iOS operates). So not useful for work mandated applications unfortunately. Not the app for me. ### 1/5 — Junk *2025-01-03, version 1.7.2* I deleted within 5 minutes of use. ### 1/5 — Paid Subscription when it’s already on iPhone for free *2024-12-17, version 1.7.2* This doesn’t need a subscription. Why would someone pay monthly for this? U can turn on this filter normally on iPhone by going to settings then to display and brightness and turn on night shift. Your welcome ### 1/5 — Don’t download *2024-11-21, version 1.7.2* Yeah sure it’s free but I can get another app with the same premise without a bunch of adds it would be an immediate upgrade if you could use the app outside of searching the web ### 1/5 — They are charging for this? *2024-10-30* Its unbelievable that they are charging for this. Nope ### 1/5 — Bad *2024-10-18, version 1.7.2* This app is garbage don’t waste your time. They charge you money for their “premium features” aka to use the app. Otherwise you will get ads that aren’t using the blue light blocker so you get blasted by these ads. You can literally do more by turning on nightshift mode on your iPhone. Again don’t waste your time with this app it’s trash. ### 1/5 — Awful interface *2024-10-09, version 1.7.2* Does not make sense. Should be an easy quick filter. One button. A few sliders for strength, opacity, etc. Makes you subscribe for $9.99 a month, with 3 day free trial. Not worth possibly forgetting to cancel subscription. DO NOT SUBSCRIBE. ### 1/5 — App doesn't open *2024-09-05, version 1.0* When you click on the App it opens a blank window titled "Trial Page" opens with a message "Minimize this window or press Command M. Beyond that NOTHING. ### 1/5 — app keeps crashing *2024-08-28, version 1.0* app kept crashing and doesnt work on mac. ### 1/5 — Doesn’t work! *2024-07-07* I paid almost 40 dollars. This aap doesn’t work. Please update your aap. It doesn’t function! Not worth it. ### 1/5 — This app costs money *2024-06-30, version 1.7.1* I want there to be a blue light filter to be used for free without spending any money! So can you please allow me to use the blue light filter for free? ### 1/5 — This product is a scam!!!!!! *2024-06-15, version 1.7.1* Do not buy! They will charge you for a full year without telling you and the product doesn’t even work like they market it! They should be banned from the apple app store ### 1/5 — Waste of a download *2024-06-08, version 1.7.1* Wants $6 a month to use… #fs ### 1/5 — Hard *2024-05-20, version 1.7.1* Piaf for it, extremely hard to use ### 1/5 — Not sure how it works *2024-04-16, version 1.7.1* I can see it working within the app but how do I successfully apply this to my entire phone for free ? Thanks ## Most critical reviews (10 lowest-rated) ### 1/5 — Bait - Switch *2026-07-19, version 1.10.0* 3 days free, then $ ### 1/5 — Waste of money! *2026-07-09, version 1.10.0* This app only allows for the blue light filter to be used while searching the web thru the app itself. The constant pop ups make it impossible to even search the web thru the app! Huge waste of money. I wish I had read the reviews before purchasing. Lesson learned! ### 1/5 — 여러분 속지 마세요 이거 항상 블루라이트 차단이 되는게 아니라 이 어플 들어가서 그 안에서 웹서핑 할때만 블루라이트 차단되는겁니다. 돈 아까워 *2026-06-01* Don’t be fooled, everyone. This doesn’t block blue light all the time. It only blocks blue light when you’re browsing the web inside this app. Please refund my purchase. ### 1/5 — Fees *2026-02-23, version 1.9.0* This app didn’t show charge until I downloaded loaded it. Now I have to figure out how to stop fees ### 1/5 — 내돈내놔 *2026-02-11* 무료3일이라면서 돈을 결제하면 어카냐 돈내놔 하 ### 1/5 — Pay *2026-02-10, version 1.9.0* Why do you need to pay to change your brightness ✌️😭💔 ### 1/5 — Paywall is ridiculous *2026-01-17, version 1.9.0* $5 a week for an app that changes my phone color? Stupid. ### 1/5 — Horrible app *2025-08-27, version 1.8.0* Bombards you with advertisements and their premium plan just a cash grab use the built in blue light filter ### 1/5 — Looks terrible and not free *2025-04-15, version 1.1.0* The defult setting is disgusting to look at and you cannot customize the settings without paying money. They definity delete reviews as well. ### 1/5 — App doesn’t open *2025-03-12, version 1.1.0* App wouldn’t open. Tried multiple times. ## Most praised reviews (4 highest-rated) ### 5/5 — 깔았는데 사용을 어떻게 하나요? *2024-10-04* 위와 동일 **Developer response:** Thank you for contacting us. First, we recommend setting the Blue Light Filter to a level that is comfortable for your eyes. Once configured, you can start browsing and reading books at night while protecting your eyes. Please note that the blue light filter is active only inside the application. Due to the way iOS works, it is not possible for one application to run simultaneously on top of another. If you have any other questions, please let us know. ### 3/5 — I think it would be great with just a few minor adjustments. *2025-07-07* Please create a feature that automatically turns on at login, and also an option to toggle it on and off using a shortcut key. ### 3/5 — 제한된 기능에 비해 과한 가격. *2025-05-14* 웹서핑 화면 조금 노랗게 만드는 걸로 매달 2700원은 굳이…? (과금 안 하면 10초에 한 번씩 광고나옴) **Developer response:** Thank you for your feedback. We understand your concern about the pricing. The free version is supported by ads, while the subscription removes ads and supports ongoing development and maintenance of the app. We appreciate you sharing your perspective. ### 2/5 — Expensive! *2026-04-18, version 1.9.0* Thumbs down on charging . --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
