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.

    Yousuf Tawakkal


    No doubt the best screen filter app. There is one thing that I excluded my launcher from the auto pause in apps it does pause but it also includes the drop down notification means it's not filtered. Can Twilight just un filter launcher and filter notification. I already fund the development of this good project.

  2. John Smith-avatar

    twilight pro unlock apk Filter turns off after phone has been idle for a while (when turning on screen again), despite disabling battery optimization (keep app running in background). I have the premium version and have set filter times to 'always'. Running Android 6.0 on Huawei Honor 7.

  3. Bravo Echo-avatar

    twilight pro unlock I like how I can change the setting so that the screen is never too bright or too dark. This app cuts out the blue light and does help with eye strain. I have used this app for over a year now, it the best one I have tried

  4. Peony Rumble-avatar

    twilight pro unlock apkpure I've used this app for years and finally got the pro to be able to have more setting options. I don't know how worth it the pro is. I wish the scheduler was easier to used and set. And I wish the pro features were a bit more in depth. The upgrades I got weren't quite worth the $3+ that I paid.

  5. Ben A.-avatar

    twilight pro unlock apk free download Just make sure to go to settings and remove start on boot otherwise your screen can stay too dark to even see in the daytime, so you reset the phone and problem solved.

  6. Adrian B-avatar

    twilight pro unlock 1.8 apk It's just not very good at filtering blue light. It very clumsily tries to do this by applying a red tint to everything. This lightens the black parts of the screen, which not only looks awful but kills your AMOLED screen. Black minus blue light should still equal black.

  7. MissBot2U, PhD-avatar

    twilight pro unlock apk download 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!

  8. Werner A-avatar

    twilight pro unlock 1.7 apk 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.

  9. Sharon LA-avatar

    twilight pro unlock v1.8 apk Have used this app for years. Soft on the eyes. Sometimes I turn off the filter and ACK! The screen lights actually hurts my eyes. Sleep better since using Twilight. Developer is very responsive.

  10. Anna Farmer-avatar

    twilight pro unlock mod apk 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.

  11. Joey Loboda-avatar

    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!

  12. Robert Larkin-avatar

    Awesome app. Well worth the $1.99 to support the app developer. I used the have confpices with this app and LastPass, but after doing a factory reset, conflicts seem to have resolved.

  13. Say Like-avatar

    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.

  14. Yarnaa Li-avatar

    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.

  15. Max Dabi-avatar

    I bought the PRO version as a 'thank you' donation for the last update covering the notification area. Bravo!

  16. Kyle Verna-avatar

    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.

  17. Gaspard van Ko-avatar

    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.

  18. Marilyn MacLellan-avatar

    Marilyn MacLellan


    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.

  19. john clarity-avatar

    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.

  20. Sebastian Aho-avatar

    Does exactly what it says with no bs. Been running on my phones for many years now. Excellent customer service also.

  21. Sean P-avatar

    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.

  22. nathaniel fernandes-avatar

    nathaniel fernandes


    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

  23. Vasileios Topouzis-avatar

    Vasileios Topouzis


    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 .

  24. Sethusubra Mani-avatar

    Sethusubra Mani


    Good app for important to everyone for protection for our eyes and Auto setting enabled for user Free

  25. Starbeamrainbowlabs-avatar



    Exactly what I'm after. My only complaint would be that the profile system is weird, unintuitive, and difficult to understand (which profile am I on? How can I update it?), but that's a minor thing really.

  26. Indigo Bodolf-avatar

    Still useful for phones that do not have a built in night-light feature.

  27. Andres Pizarro-avatar

    I've had the paid version for years and love it. Money extremely well spent.

  28. angry pigeon-avatar

    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

  29. John V-avatar

    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'.

  30. werdwerdus-avatar

    it now filters lock screen, notification, and notification bar! awesome! thank you

  31. craig jordison-avatar

    This app is for the main one and work's okay to help with the blue light that makes it hard on your eyes before bed

  32. Greg m-avatar

    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!

  33. R K Hayden-avatar

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

  34. MT P-avatar

    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.

  35. 567indian-avatar

    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 .

  36. Ooh Kana-avatar

    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.

  37. Aman Sinha-avatar

    add some different colours, work on screen performance

  38. K. G.-avatar

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

  39. Craig Dowling-avatar

    Positive for helping me to sleep when I need to use my phone for music or funny videos. Sometimes I just like to place my phone away but twilight is an essential app for nighttime phone use.

  40. Pranjal Vats-avatar

    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...

  41. Michael Erb-avatar

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

  42. Hriday Vyas-avatar

    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.

  43. Three Odd-avatar

    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 .

  44. James Dodgshun-avatar

    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

  45. For Google Stuff-avatar

    For Google Stuff


    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.

  46. Hector Fuentes-avatar

    Now supports notification area filtering. Loving it!

  47. Kathryn Pfleging-avatar

    Kathryn Pfleging


    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

  48. Leila H-avatar

    Cannot live without this app. Bedtime and times when I have migraines are now less painful and more productive with twilight.

  49. Lloyd Randall-avatar

    Good, can be confusing in menus, but works. Its a Shane all phones don't come with this feature built in

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