3. Importantly, customers can learn from other customers in case the issue is a common problem that has been solved before.

1. 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. 2) AMOLED screens: We have tested Twilight on an AMOLED screen for 5 years without any sign of depletion or over-burning.

2. 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.

3. 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).

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

5. 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.

6. 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. See references below..

7. Intrinsic period and light intensity determine the phase relationship between melatonin and sleep in humans Kenneth P.

10. In order to filter also your notifications and lock screen the app may ask for enabling Twilight Accessibility Service.

11. Twilight also syncs your Wear OS screen with your phone's filter settings.

1. It certainly deserves to be an Editor's Choice.Turned on a red light filter in UI and cannot turn it off? I granted app permissions and my system UI now has a pinkish filter on the settings app icon and dropdown menu.

2. I've even reduced blue light on my television and I feel sleepier earlier in the day.It sucks that it asks for location access every time even though I don't want or need the feature that uses my location.

3. Of course, there are quite a few blue light filter apps in the playstore that function very well, however, Twilight is exceptional and has never given me any problems whatsoever.

4. I don't like that it prevents Gmail from performing certain functions: - it doesn't allow Gmail to accept a selected email address and then move on to selecting other destination email addresses, be it regular, or CC or BCC.

5. Will play with it later next week when I have time.very very helpful for removing the agitation the blue light causes when I look at my screen.

6. I like the presets that are given and how it lets the user always use the blue light filter.

7. Fellow users: don't get too many alarms on your lineup (I would do this because there were different times I would need to do things on different days, and I found it easier just to turn an alarm on without having to program new ones).

8. One discovery I made because of this is that if you have too many alarms sitting inactive (how many is that?... 🤔), some of them will randomly turn themselves on, and go off at odd times.This app was downloaded to all my phones and tablets and was very reliable and unobtrusive.

9. Please, remove these useless widgets.Recently this app has been refusing to turn on in quick settings.

10. The overlay doesn't work on everything, but generally it works more times than it doesn't.Great app, and great customer support who immediately recognized my issue with the floating icon.

11. I get blinded by blue light each time I have to do this.
