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 any more..

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 flux of blue light emitted by 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.

1) Bed reading: Twilight is more pleasant on the eyes for night reading. Especially as it is able to lower the screen backlight far below the ability of the backligt controls on your screen

2) AMOLED screens: We have tested Twilight on an AMOLED screen for 2.5 years without any sign of depletion or over-burning. If properly configured Twilight causes less light emission (by enabling dimming) with more equal light distribution (dark areas of the screen such as the status bar get tinted). This may in fact increase your AMOLED screen life time.

Permissions
– location – to find out your current sunset/surise times
– running apps – to stop Twilight in selected apps
– write settings – to set back-light
– network – access smartlight (Philips HUE) to shield you household light from blue

Absolutely amazing. As a kid with school, I use my phone a lot before sleeping which makes it hard to go to sleep because of the blue light thingy on screens. I’d recommend it to anyone who uses their phone before bed as it really helps you get a better night’s sleep. No adverts popping up everywhere like most apps, and it doesn’t affect my phone in any way. Xx

Dear developers: I have adored this app for years on my s5. I just updated to an s8, and had it still working perfectly… Until I updated the android software last night. Now, it doesn’t draw over the status bar at the top of the screen, or the navigation bar on the right hand side. It results in bright, bright light straight to my face during nighttime while trying to use my phone. I have gone through twilight settings looking for a fix to no avail. Please solve this issue, or guide me to fix it. I miss not having this issue, and will need to start looking at other apps if it is not solved.

So far the best red light screen overlay app I can find. My laptop has recently kicked the bucket, so I’m using my older tablet/keyboard combo. Talk about migraine city!! I used Iris for my laptop (it was awesome), but found their app completely lacking. So far, I’m liking this app. We will see how it goes long term.

I’ve been using this app for my past phones and never had any problems, works just like it should. I just got my OnePlus 6 and unfortunately it’s not fully functional with the OnePlus launcher at this time. The buttons, status bar, and notification bar areas are all unaffected by the screen overlay with the OnePlus 6, meaning the color change and dimming don’t hit them. Otherwise, big help when using my phone after sunset.

This apps makes it so much easier for me to fall asleep! I use my phone for a lot of things, so it’s not usually possible to have a “no screen time” before bed. It’s hardly a problem thanks to Twilight!

Heather Barter
I have loved this app fer years, using it on my Samsung devices. Recently, I got a new phone with Oreo, and I have noticed that it does not change the blue light levels from the bottom part of the screen where the home button is, as well has for the notification drawer. This is especially annoying, since I am blinded whenever I go to check my notifications. Please fix this! Thanks!

Alex Goguen
It was working great but the newest Android update really destroid the app unfortunately.. The locked screen now overly orangifies itself and anything that overlays the default UI is now no longer filtered (no orange on overlaying items such as text messages and messenger conversations 😟). I’ll return to 5 stars once these are fixed.. or a reply explaining why it can’t be fixed is given 😯.

I don’t know about the medical benefits to this app, but if you set it to be red as possible, then dim your phone all the way down, you can use your phone in the darkroom without fogging your paper. I’d totally pay money for this. I don’t know why this app isn’t marketed towards analog photographers. You’re losing an entirely new demographic.

Kiki Yushima
I love this app so much. I’ve been using programs like f.lux and redshift on desktop for years which has left me physically unable to look at blue light without pain. This app is super simple to use (especialy when compared to redshift) so I recommend to anybody that wants to limit their blue light.

App User
Skeptical by nature, I had postponed giving my review, thinking that there is really nothing that the app is helping me with. However, I think the time has come for me to admit that I have truly experience a difference on my ‘falling asleep’ pattern everytime I use the app. It may work different for everybody but, at least in my case, it really seems to work. I have never posted a review about any app or product before, but I thought that, this time, I must show my gratitude to the creators of this app. Thank you.

This is great app even if you don’t pay. My only problem us that it instead of TAKING AWAY blue like on my PC, it ADDS red! Not only is this totally un-logical and possibly just lazy, it turns black into brown! Not like it should be where black stays black, and only the hue of colors are changed, not brightness. Still five stars for good quality free app.

App User
I used to adore this app, I’ve used it for years and bought Pro for all the extra settings. But with the Android 8 Oreo, it’s impossible to filter the lock screen and the notification tray. I know this is because Google screwed everything and rendered virtually all blue light filter apps useless but PLEASE find a solution.

Kevin Barr
Was very good when I first installed the app. I USE custom settings. Since the latest update it doesn’t seem to be working correctly. It turns it self off and then turn back on. I’d give it 5 stars but not sure what the problem is with it now.

Mike Kelly
Worked great until it completely and totally stopped doing anything whatsoever after the last few andriod updates. No setting I choose will make the slightest difference to my screen. I switched to Blue Light Filter. This app literally does nothing at all on my phone any longer.

Sarah Jane
Love this app SO much. I’m usually up until 1-3 am on my phone reading or something, and it was killing my eyes. Tried this and I have no issues AT ALL. I fall asleep faster and it’s just really great quality 💕 Thanks so much twilight.

Josh Bailey
Used to work amazingly but a couple up infixed issues on my S9. It doesn’t work on the notification tray, so pulling that down in the dark blinds me. Also, it has this issue with wallpapers where the wallpaper will stay in red tones after twilight has been turned off.

App User
Interesting app, although a bit faulty. The user should be able to select the language. Also, the profile configuration system is a bit of a mess. Finally, I’ve noticed the location feature doesn’t work quite all that well either, since toggling the “detect your location” button does not disable the map below, as I feel it should.

Jean-Philippe Bégin
Samsung G7 recently updated to Oreo wont permit twilight over the drop down window (android settings). Not sure if its a misconfiguration but it was working before the upgrade to oreo. Incompatibility with the Facebook app. You got to pause Twilight to be able to get the keyboard to show up when you want to share whats on your mind.

Ashley Vandermeer
Doesn’t work well with the new android OS. Lock screen either is super red or not filtered at all so its blinding at night. And the pull down task bar is not filtered either and its white so it’s quite bright

App User
This app is saved my vision, I use to suffer from blue light eye strain. Now that I have this app I’m adding it to all my devices and now there’s no more eye strain. Definitely recommend this app for those that have been experiencing blurred vision .It’s probably from the excessive exposure to the brightness of the blue light.

Zul ari fadlillah
I’ve installed this already for a long time. I never meet problem when i’m going to install apk. The problem comes to my phone after i update this app. I cannot tap ‘install’ permission. Please fix it. Thanks

Sick Pixie
Really like how customisable it is. But the set custom time for it to come on has stopped so I keep forgetting about it and getting sore eyes when I’m going to bed. I also think having to have both the original and pro widget is a bit daft, why not merge them once youve paid for pro so you only need one?

Amber Fitzsimmons
I used to LOVE this app. It was perfect for my descent into sleep. However the newest Android update has rendered it useless. I see the constant “email here for help,” but that isn’t going to do it. The developers need to adapt so all of us who truly love this app come back. I don’t want the stock filter that sucks, but that is all I have now.

Kristin Klun
I love the customization and the gradual fade into full twilight mode. I like that there’s a quick setting button as well! As a nursing mom, I turn it off and on as needed overnight to keep the screen brightness low (for browsing) or high (for watching shows to stay awake). Only complaint is that any screenshots taken while twilight mode is on save as twilight mode, meaning they look red and dim. Photos taken from the camera do not, thankfully! Edit: I’ve updated my Samsung S7 to the latest software update (Android 8.0.0) and the app no longer works in the lock screen or the pull down notification tab. I know this is an issue caused by the latest update, but I’m bummed about it.

It’s really good for what it is, however if you are an avid f.lux user then you will notice it isn’t the same. Twilight feels like an overlay, while f.lux feels like it transforms it in a much different way – it’s hard to explain. Also, twilight will make your screenshots colored as well, which f.lux does not. All that said, twilight is still 100% worth using and I assume the perceived flaws I have with it are due to android limitations. Twilight also seems to have a lot more fine tuning of the color, shading, and brightness level that f.lux doesn’t seem to have, which is very nice. Absolutely recommend using this to anyone who reads their phone at night or who wants to turn their brightness down further. Edit: added a star for instant feedback, never seen that before in my life. Thanks!

I’ve been using this app for a very long time already and I use this in order to hide my bright screen from my mom whenever its past bedtime. But no matter how I wanna stay up so so late, this app helps me fall asleep. So. Thanks! Saved me from my anemia. 💕

Krzysztof Gadek
I used to use this app on my old phone, until I upgraded to a pixel. I am not sure if you guys have even tested your app on the pixel because it just straight up is just a complete failure on the pixel. Sure it find the screen, but as soon as you pull down the notification bar your just blasted in the face with full brightness.

Constitution Defender
I don’t know if it really helps me with sleep, although I do know blue light will disrupt sleep patterns. And I do know this app filters it out. The main thing for me is how much stress it’s taken from my eyes. Holy cow. I had no idea just how uncomfortable they were at the end of the day.

Nabi Kambiz
Very helpful. My current phone can’t dim the display all the way. This app solves this problem. Now I can use my phone before going to sleep without putting strain on my eyes. It really works. Love this app.

Hashim Abdul Quddus
Good app! Seems to be light on resources. I do want to mention something VERY important and I think the developers should note. (This is why I gave it one star, to bring to people’s attention, otherwise I would give this a five star). You must pause or stop the program when installing 3rd party apps like from Amazon AND if wanting to use a VPN like opera VPN, turbo VPN, etc, this program MUST be paused or stopped first. It took me forever to figure out why I was having problems until I just by trial and error, figured this out. Please note this clearly on the app description and I will change my rating to five stars.
