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. ### 2/5 — Expensive! *2026-04-18, version 1.9.0* Thumbs down on charging . ### 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 ### 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. ## Frequently asked questions about Blue Light Filter ### What does the Blue Light Filter app do?
