Are you having trouble falling asleep? Are your kids hyperactive when playing with the tablet before bed time?
Are you using your smart phone or tablet in the late evening? Twilight may be a solution for you!

WARNING: Android O does no allow the app to cover your notifications and lockscreen anymore. We have some workarounds like wallpaper filtering etc..

Recent research suggests that exposure to blue light before sleep may distort your natural (circadian) rhythm and cause inability to fall asleep.

The cause is the photoreceptor in your eyes, called Melanopsin. This receptor is sensitive to a narrow band of blue light in the 460-480nm range which may suppress Melatonin production - a hormone responsible for your healthy sleep-wake cycles.

In experimental scientific studies it has been shown an average person reading on a tablet or smart phone for a couple of hours before bed time may find their sleep delayed by about an hour.

The Twilight app makes your device screen adapt to the time of the day. It filters the blue spectrum on your phone or tablet after sunset and protects your eyes with a soft and pleasant red filter. The filter intensity is smoothly adjusted to the sun cycle based on your local sunset and sunrise times.

PRO features
- more than 2 predefined profiles
- adjustable transition time
- option to turn off Twilight service altogether during inactive times
- new features will often first appear as PRO

Thank you very much for your intention to support our development. This is a pro application for the Twilight app. Please install on top, do not uninstall Twilight first.

Reviews From google play store

It works really well for reading in bed in the dark. This makes it comfortable on my eyes and my partner can sleep while I read

Pro didn't really have anything I'd immediately need, but I bought it to support the developers (as a developer). Been using it for 4+ years and it's been great.

Loved this app until it stopped working once I denied location access. There is no reason for this app to know where I am. Stop it.

Like having the unlock, love the app! Used it for so long I forget it's not just stock android

Twilight makes it so much easier to use your phone at night or in the dark. I've been using it for years and highly recommend it.

Just perfect. Adjusts according to local sunset.

I've been using this app every night, for years. When I get a new phone, it's the first app I install.

Control Clarity Simplicity Effectiveness Love it!

Simply does not work Loaded and it does not run. Wasted money

User friendly and effective

Love it. It helps me sleep better at night

Solid app, been using it for years

The best night filter I could find. It is so customizable. Before bed I like to make my screen as dark as possible and this app allows me to make it even darker than the phone settings allow. I've been using it for over 5 years and wont switch as long as it keeps being the way it is now.

Usually good, but latest update of either this key, or the utility app, broke Android 5.0.1. Unable to fully charge battery via usb. Lucky still had the prev version in my tablet, so reinstalled that. Problem went away.

I have used this app on my last few phones without issue, except now with the S10. The app cant seem to draw over the notification area at the top of the screen when the bar is transparent. For example: when playing a full screen game, there is a large gap at the top of the screen that Twilight wont cover. It's hugely distracting, especially at night. Unfortunately is makes the app almost not worth using. Became a pro member to hopefully help fund fixing this bug!

I bought this app and supported it simce its release, I know its not you guys/girls fault (darn you google), but since it can no longer filter the latest Android OS (didnt work for Android O and now P) it's become a little redundant 😟 it can't filter my notifications bar or the bottom of my screen. Hope you find a way around this, been with you guys since the beginning.

Loved this app for many years, but now I have Android P which has the same feature built in. But for any older Android, this one is the best, it automatically disables when permission screens pop up and offers a quick setting to quickly disable, for example for showing qr code at the movie theater.

Doesn't work properly on this phone. The fix suggested by the maker of the app didnt work. Then he just stopped responding to me. This pro version is useless to me and I'd like a refund. Don't buy it, folks Edit: Hi, whats the point of telling me to email you? As I say, I already did a long time ago when I had the initial problem. Your fix didnt work and then your ignored my follow-up emails. Search your inbox and find my last one to you if you really want to help.

It's a great app used it for many years, but my phone has a dedicated night mode now, so I no longer need it anymore. But it was great when I used it

Been using it for a couple of years now, bought the pro version almost immediately, and use it nightly. Love it. Once in a while it will suddenly shut off for no apparent reason, leaving me blinded for a few seconds, but then it'll come back on in about a min. It's perfect for night reading in the dark at bedtime. Highly recommend it. Thanks Twilight for being one of the awesome apps that keeps updating, even after all this time! And, for keeping it simple!

Updated review: So the developer answered back with an answer from their FAQ. So its a normal problem. Emailed them again for a solution and they never replied for the 3rd time. Another app does the same thing with no problems so why cant a paid app work better? Always crashing in the background. Custom settings always revert back to default. If youre watching a video it will crash on you. If you stop the app it will turn itself on. Emailed developer twice with no reply. Ive paid for the app so i deserve a reply or for them to fix the problem.

The Autopause function stopped working. It doesn't stick. As soon as I back out of the settings, it's gone.

This app is great! I bought the Pro a week later after installing the first Twilight app. I have a real sensitivity to glares and the sun option on the Pro works great during the daytime, it reduces a lot of Glarus for me. I love that you can turning the twilight app off with just a touch or pausing it. Also at the end of the day, I am not really squinting my eyes or rubbing them anymore after coming home from work and watching TV at night. I installed it also on my Ipad.

Been using the free version every day for over a year now with no complaints so I figured forking out a few bucks for the full version is overdue. My only complaint was how it had weird issues interfering with screen overlays from others apps but either they fixed it or it's not an issue anymore with newer versions of android.

This app ALWAYS messes with my background wallpaper and there's no quick way to disable/ stop the app. Otherwise it just keeps running in paused mode. It's annoying beyond belief. Everytime I start it up it somehow messes everything up. Shame I paid for this. Just add a quick play/ stop function in there. Why the F do I need this to be running during the day!? It's only useful at night and even then it makes my background disappear. Looking for a replacement app.

Have paid for the app but still does not work properly. If I close the app the blue light come back, it is like the app stop working. It gave me a notification to give it admin access but I can't find the app in the options. Please help

I used to love this app ...but now its useless ...everytime (no matter the settings )I get a notification bright light hights me out from nowhere as I had not use any filter ... Or if I slide from up down for thw quick settings (WiFi and etc ...)terrible to thw point that its useless .

This app is noice, I use the pro version, everything works well but whenever I change my wallpaper it reverts it back to the old one or the default one that came with the theme for some reason. I have a redmi 4 btw

Pro app has a bug - Android back soft key fails to close app (this worked fine on your free app version). Fix this issue (or maybe add a 'close' or 'minimise' option in its menu) for five stars. App is fantastic, apart from that bug.

App is great . But there is no red light in the notch area and on the lock screen . Please fix it . I have upgraded to android pie .

This does the trick. Quit nagging me about permissions. Thanks for the pro options.

Had been using the basic version for about a year and upgraded to Pro. Definitely worth $2.99 for the added features such as 'Sunset offset' and 'Stop app when not filtering'.

Ive been using the free version for at least 3 years and it's always been great. I honestly don't even care about the pro features. I just wanted to say thanks for such a great app!

Notification ads for your other products, in a Pro version. Not good - I pay to avoid ads, not to get them.

I love this app,,have been using it for a while now.I bought the pro version,I know there isn't much in this pro version but the developers deserve the money they asked for...

I am running marshmallow , used to work good on lollipop but now it is continuously asking me location access and permission to draw over other app i have enabled both but for some reason it is asking same permission again and i am not able to customize setting.Help .

Uninstalled from phone and reboot but cannot get the red tinted off my phone

love this app . have become so used to the dimming effect I now find non twilight screen blinding

It makes my entire background extremely red (same color as the logo) as soon as it starts working. Doesn't fade or anything

Decent app. But keeps changing my wallpaper everytime I use it. Please fix it. I love this app but hate the fact that the wallpaper keeps changing everytime i use it.

It changes my lock screen wallpaper to red one but then it stays the same even after twilight active hours. Please fix

Been using this app for years, never had any issues across like 4 or 5 phones

Perfect low light filter that keeps my eyes and brain happy.

very flexible settings, convenient to use 👍

Excellent, my eyes are very grateful been using this app for couple years now & I love it.

Have been using this app for years now. Bought the pro version to support the developer.

Does the job well. I am now reading more comfortably. Very pleased.

Using on multiple devices. Very good!

Best light filter app for sensitive eyes

A good app to save your eyes from strain...

doesn't include the notch on my phone. p smart+. please fix this ;)

This has been resolved and it works perfectly now!

Use it for a better sleep and for your eyes

Best blue filter app on market.

loads on bugs

They increased the price by 10x! Was INR 30, now it's INR 300. Not worth the price now.

Probably the best nightime screen app on the marketplace. 5*

great app, very helpful

Helping me every day

I bought this app for some of Twilight Pro features and to support Twilight developers.

I love it!


I love the blue light blocker

Please make it work on notification bar in Android O

Nice app keep up the good work

Appreciate the developers work on this!

great app for my eyes

Excellent; does what it claims to do

This app convinced me that eink is useless technology.

it works well.

It doesn't work , please repay my money

Nice. Must use.

awesome.. totally worth it

It's useful

Awesome to the max

Where is your pro feacher

Unstable A F.



Twilight is messing up / blocking use of other apps. Which is a shame cos otherwise it's the perfect blue light filter. Please fix.

Wonderful. Works great for me, I'd recommend it, and I'm looking forward to exploring the new options via PRO. Even of there isn't a whole lot that's new... I believe they earned the darn $2 for doing such a great job!

Wonderful app. My eyes are hurting less with this application. I hope it's perfected with new eye-friendly features.

After oreo update app does not work on notification panel and lock screen please fix this

I've been using this app for the last 2-3 years and absolutely love it. I love the tint of the color and love how it has a sunrise to sunset option by default. I've never been disappointed with this app so I decided to buy the pro version today.

Would be great to have an option to have a different schedule on different days (like later turn on on Fridays and Saturdays or something)

Leider funktioniert die Helligkeits-Dimmung und die Rotlicht-Funktion nicht, wenn man die Statusleiste runterfährt. Sonst super App. (Huawei P20Pro)

Great app. Been using it for the last few years. The interface is very elegant, and it does exactly what it says, efficiently.

A gray scale feature would be a nice addition.

Worth my money🌟

Mejora mi experiencia para dormir

It used to work on this phone Wiko Lenny3 Android 6.0. Not any longer 🤔

It works.

Still works perfectly.





The app no longer functions in many menu settings on Oreo 8 which now is glaring white due to the upgrade. An update needs to come out for the app as it renders the app useless when you even swipe down from the notification bar or go to unlock your phone.

This is a great app. It simply does what it says without requiring extra permissions, ads, or other junk. I suggest buying Pro just to support a good developer, even if you don't use the Pro features. There are so many bad apps out there, it's refreshing to find a competent and professional one like Twilight!

I use this app every night & I really like it. My one issue is the dimmer setting to make my screen darker (while also being darker orange) doesn't get dark enough and I have to use a separate dimming app to achieve my desired results. I like my screen dark and barely emitting light at the wee hours in the morning I'm going to bed- like I was reading by a candle that was burning out- or how the sunset turns into the pitch black darkness of night (or close to that). So if you add a darker setting with the amber color that is almost pitch black/orange, I'll give you the fifth star! But still, I love the app, and I wouldn't be able to sleep well without it =^)
