Blue Light Filter for iOS
Free
iOS devices come with a built-in Night Shift feature that reduces blue light by adjusting the display colors to the warmer end of the spectrum, making it easier on your eyes during nighttime reading.

Our take
A handy feature for iOS night owls.
Alright, so this Blue Light Filter for iOS, huh? Sounds like one of those things that you think you don’t really need until you actually try it. The idea is it reduces eye strain, especially for those of us glued to our screens late into the night. And honestly, it does a decent job at it. You turn it on, and the screen takes on this warm hue, kind of like everything’s in a cozy sepia tone. It’s not just a gimmick; I noticed a difference in how my eyes felt after a long session of scrolling or reading.
That being said, it’s not perfect. The color shift can be a bit jarring at first, especially if you’re picky about how things look on your screen. Some apps and images might seem a bit off, and if you’re doing anything color-sensitive, like editing photos, you’ll probably want to turn it off. It’s a tradeoff between eye comfort and color accuracy, and I guess it depends on what you're prioritizing at the moment.
Now, here’s where it gets a bit tricky. The app's interface could use some love. It’s not the most intuitive thing out there. I mean, it’s not rocket science, but some settings seem buried where you wouldn’t expect them to be. A bit of poking around is needed to get everything set up just the way you want. It’s not a deal-breaker, but it’s one of those minor annoyances that could be smoothed out with a better design.
On the upside, it’s not a battery hog, which is always a plus. Some apps just drain your phone like it's their job, but this one runs in the background without causing much fuss. That’s a relief because the last thing you want is a dead phone just because you’re trying to protect your peepers. It’s solid in the performance department, letting you focus more on using your phone and less on charging it.
So, is it worth it? I’d say if you’re someone who uses their phone a lot at night, it’s definitely worth a shot. It might take a bit of getting used to, and there are those little quirks, but overall, it’s got its merits. Your eyes will thank you, even if your inner designer might grumble a bit about the colors. Just remember, it’s not going to be a magic cure for all your screen-related woes, but it’s a step in the right direction. Give it a whirl and see if it makes your late-night screen time a bit easier on the eyes.
