Description
Are you having troubles to fall 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!
Are you using your smart phone or tablet in the late evening? Twilight may be a solution for you!
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.
Get more from Twilight
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.

Great for studying late I love to use my tablet for reading my textbooks before bed, but I hate the strain that regular screen settings cause my eyes. This app allows me to study without getting a headache.
Omar Miller
It closes/quits all by itself At times, when i am surfing the web and reading an articles, it just somehow, shuts down. I would have to go to the app for it to turn back on. I gave it 5 stars cause its an incredible invention, but please try to fix this issue.
Renato Laporte
Useful I've been searching for this for years... And find that it comes from the same dev of sleep as android, the best alarm system I've seen. I like the bed reading mode, my xperia don't dim the light enough... This app makes reading a website on bed a joyful experience.
John Snyder, Bellvue, Colorado
Non functional Simply too flawed to use. Works for a while then quits for no apparent reason. This on and off is probably worse for the eyes than just dimming the screen. I wish the developers would get this right as it is a good idea.
Eric Nupp
Great Not your average blue hue filter. Syncs with the sunset and sunrise times, your bed time and alarm time (linked to my Sleep Droid) or custom times. I have it set to sun and it does it's thing on it's own. Set up and profit. Customizable, plenty of features, and has never crashed. Overall A+ app
Alex McNally-Gagnon
Weird bug I like this app very much. But there's a weird bug that makes it impossible to install .apk files in file managers when the app is enabled. You simply can't press the install button. Please fix it for a shiny perfect score!

Hello, the latest version is fixing the load on boot issue. Thank you.

Started working immediately I like to use my phone at night before bed but it strains my eyes and makes it hard to sleep. I saw this app in the store and decided to try it. After dimming my screen I immediately felt less eye strain. I slept well that night. It did add an hour to my sleep however, causing me to sleep through my alarm and be late for work. I got fired today for being late. Now I won't be able to pay my phone bill. This is a great app and you do not need a data plan to use it so I can still use it on my serviceless phone
This app is ...by early observation, has a uniqueness that deserves complimentary marks outside of the 4 stars. Simple design that when once set, you will use your phone as if nothing was different with your device, and yet you will become tired having the need to sleep! One speculative examination would be...just how much battery consumption is being used throughout the day?
Easy on the eyes, seems to work. Regarding the application itself, Twilight does what it "says on the label" and seems to work reasonably well, though occasionally it will "flash" back to the regular backlighting for a brief moment... As for the concept, whilst I can't positively assert that Twilight works, the science suggests it does and there is no doubt that using this is more comfortable, particularly in low-light conditions.
What's New
3.5
- option to cover also the translucent navigation bar on KitKat
- Farsi translation (many thanks to Farzad)

No straining of eyes while reading. After applying the filter, display is almost as good as any eBook reader. Almost made my kindle redundant.

This app does what it claims to do. Can feel the difference immediately. I purchased it after the first use itself. Only suggestion I have for developers is to keep one app only got users having key. I don't like two icons for one single app.

* If you want to install an app from a third party store such as Amazon. Please turn off the filter first to enable installation.
* When capturing a screen (screenshot) turn off the filter first, otherwise it will apply to the captured screen as well.
* If other screen adjustment apps such as controller of lux, screen darker, screen dimmer, night screen filter and more are running on your smartphone or tablet, the screen may turn too dark to operate properly. Please disable or uninstall other screen apps before using the bluelight filter.

Sleep Cycle
Sleep Cycle is a simple time calculator that makes it easy to manage sleep cycles, so that you wake up well-rested. The calculations use findings from scientific studies that show the human brain sleeps in cycles, and that the end of each cycle is the best time to wake up at.
Sleep Cycle works in two modes:
- Fixed Wake-up: Allows you to set your desired time to wake up, and suggests the optimal times to go to sleep based on your input.
- Sleep Now: When you're feeling tired and want to go to bed right away, this mode will display the best times to set your alarm clock to, based on your device's current time.
Good Sleep (Similar to F.lux )
Life changes a lot according to the quality of sleep.
This App was made for people who pursue the quality of sleep.
Feature
-A red filter is covered over the screen of your smart phone as a bedtime hour is approached.
->Since a pale light of the screen of a smart phone is close to the light of the sun of daytime, it is said that it will mistake if a brain is daytime, and a rhythm in the living body is out of order.
-While you are sleeping, your smart phone is made into airplane mode.
->It is said that the electric wave which a smart phone emits prevents your sleep.
By setting it in airplane mode, waking by mail arrival and consumption of a battery can also be prevented at the time of sleeping.
-The inside of a bedtime hour covers a dark filter over the screen of your smart phone.
->When you awake midnight and a smart phone is taken in its hand, it prevents the brightness of a screen and being wide-awake.
-While you are sleeping, your smart phone is made into silent mode.
Music Therapy for Sound Sleep
Music Therapy for Sound Sleep is an android music application based on the famous EEG to optimize human brains. For a necessary sound sleep, Low Speed Alpha Wave set in this app will comfort your mind, assisting you to fall asleep smoothly.
★ Music Therapy for Sound Sleep (Full Version) with 8 music pieces and 12 ambient sounds is now available on Google Play!
https://play.google.com/store/apps/details?id=imoblife.mtsoundsleep.deluxe
Enrich Your Imagination with a Sound Mixer in the latest version!
The latest version of Music Therapy for Sound Sleep provides a group of relaxing natural sounds for you to choose and mix, creating your own fantastic ocean scenes. These sounds help enrich your imagination thus to further relax in a pleasant surroundings with ocean waves and soothing rains. It is totally up to you to customize each track with one or several ambient sounds, with volume bars separated from the main piano melodies.
Totally different from the so-called leisure music, subliminal music embeds Alpha Wave to various musical pieces by delicately setting the rhythm to a certain frequency, while stimulating imagination with certain sound effects. Listening to the music, our sub-consciousness is awakened. It is guiding us to a brand new discovery of our potentials, to relaxation, and to creativity.
Low Speed Alpha Wave has a frequency from 8Hz to 9Hz, which stimulates a state at which one is nearly asleep and cannot think clearly. To generate such a frequency in one's mind, binaural beats are applied. For example, if the left ear is presented with a steady tone of 500Hz and the right ear a steady tone of 508Hz, these two tones combine in the brain. The difference, 8Hz, is perceived by the brain and is a very effective stimulus for brainwave entrainment.

EasyEyes Free
Trouble sleeping? Device screen too bright even on the lowest brightness setting? Want to give your phone a warm look instead of that eye straining blue gaze you see at night? EasyEyes is the solution. Inspired by Flux for the PC, EasyEyes changes your device's color temperature and creates a screen filter to reduce eye strain when looking at your device at night. Looking at a lower and natural light source gives your body a chance to produce more melatonin, helping to provide you with better sleep. With EasyEyes, you can now look at your phone at any point during the night while keeping your eyes in an easy, restful state.
Features:
* Simplicity of one click on/off.
* Temperature Filter - Turn the blue gaze of your device with warm lighting.
* Brightness Filter - Set the brightness level below minimum brightness.
* Lowest System Brightness - Set the system brightness to the lowest setting.
Paid App Features:
* Automatic Scheduler - Set EasyEyes to turn on automatically night after night.
* Sunrise and Sunset Time - Set the schedule based on the sunrise and sunset.
* Disable Button Backlight - Turn off backlight on hardware keys.
* EasyEyes Widget/Shortcut - Quickly and easily turn on and off EasyEyes.
* Tasker support integration (Action available in "Plugin" category)
What makes EasyEyes different? EasyEyes works on all devices as well as covering the entire screen. It also does not interfere with Android's system brightness giving you more control of your device's brightness.
Why upgrade to the full version of EasyEyes?
Using the automatic scheduler, all you have to do is set the time once and let EasyEyes do the work night after night. It will even set the times based on the sunrise and sunset wherever you are in the world. With the timeout feature of the scheduler, EasyEyes will know when to turn itself back on even when you have disabled it. You also have the ability to enable and disable EasyEyes in one click using the EasyEyes widget. Still see a slight glow with EasyEyes on? All of these features, ad-free, plus more on the way.
Common Issues:
"Cannot click the install button of .apk files" - The android operating system seems to disable the installation of third party .apk files whenever the system_alert_window permission is used. Until a work around is found, you will have to disable EasyEyes temporarily to install a third party app.
"The onscreen navigation keys are still too bright" - With the "lowest system brightness" option, the white keys will be dimmed down to their minimum brightness.

Baby Sleep Instant
Help your baby to fall asleep instantly using classic monotonous sounds (lullabies) proven to be effective by generations of parents!
Works flawless also on Android 4.3!
Why is my baby crying?
Your baby is fed, has a clean nappy, no issues with colic, you were playing with your baby but still it is crying? The baby is probably too tired, but at the same time unable to fall asleep by itself. This is a common situation of newborns and a situation when Sleep Baby Instant can help the most.
Sleep Baby Instant helps your baby to fall asleep using classic monotonous low frequency sounds proven to be effective by generations of parents:
Such sounds include:
• Shower
• Washing machine
• Car
• Hairdryer
• Vacuum cleaner
• Shush
• Fan
• Train
• Musicbox
• Heartbeats
• Sea and stream...
From practical experience, we have learned that such sounds are more effective as a lullaby than tones, music or sing.
To start using Sleep Baby Instant put your phone to a hearing distance from your baby, choose one of the available sounds, set a timer and start the playback.
We do highly recommend not putting the phone closer to the baby than necessary and turning on airplane mode as well as muting alerts during the entire use of this app.

Twilight Pro Unlock
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.
Twilight
Are you having troubles to fall 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!
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.
Please read the basics on circadian rhythm and the role of melatonin:
