RedLight is a blue light filter for Android TV and Google TV. It lays a translucent warm color over the whole screen, including every other app, so whites turn soft amber and the picture gives off less blue light in the evening.

Try everything free for 14 days. After that, a one-time purchase keeps it all, with no subscription. Without it, the filter toggle keeps working at 3000K and 40%, and your settings wait for you.

Simple to set from the couch
• One toggle turns the filter on or off, with a 1 second fade.
• Temperature goes from 1000K, a deep red-orange, to 5000K, close to white, in 250K steps. The default is 3000K.
• Strength goes from 10% to 80%, in 10% steps. The default is 40%.
• Extra dim darkens the whole picture further, up to 70%, for the darkest rooms.
• A dark interface you drive with the arrows on your remote.

A schedule that runs itself
• Pick a start time and an end time, in 15-minute steps, and the days of the week.
• Or start at sunset and end at sunrise, up to 3 hours earlier or later. Sun times come from your TV's time zone, with no location permission.
• Scheduled changes fade in and out slowly, over 1 minute to 3 hours, chosen separately for each.
• Changes missed while the TV was off are applied when it starts again.

Over everything you watch
• The warm layer covers every app on your TV.
• It comes back on its own after the TV restarts.

Good to know
• RedLight changes the color of what is on screen. It does not touch your TV's brightness, backlight or picture settings.
• Because the filter is a layer of color, dark areas warm up too: blacks take on a warm tint and look slightly lighter. Extra dim darkens everything evenly, blacks included.
• Strength and extra dim together always let some of the picture through. The stronger the filter, the less extra dim it leaves room for.
• The app is available in English, French, Spanish, Italian and Russian.

About the "Display over other apps" permission
RedLight needs the "Display over other apps" permission. Android asks for it whenever an app draws on screen while you use other apps, and that is exactly what the filter does: it places its warm layer over whatever is playing. RedLight uses this permission only to draw the filter.

About the "Alarms & reminders" permission
On Android 14 and later, RedLight asks for the "Alarms & reminders" permission when you turn the schedule on, so that scheduled changes happen on time. Without it, the schedule still works, but Android can run its changes up to an hour late.

Requirements
• Android TV or Google TV
• Android 8.0 or later
