CF.Lumen - Letting Nature Control Your Android Display

I guessed that everyone would be going through the beginning of the week laziness and unwillingness to work, so I though that instead of writing about an app that could help you live your life better in some way, I should write about an Android app that simply amazes you. Since we already have lots of people (all our aunts) telling us how to live our lives and what we should do and where we are going wrong, how we need to start thinking about marriage and that Cheetos is not a real meal (give me a break!), I did not want to do that today (I know I do the same thing taking the app route, only because I am your well-wisher and now I sound exactly like your aunt). Anyway, today we are going to review an awesome app called CF.Lumen, an app that is not going to help your day to day routine directly but will let nature help you out. CF.lumen adapts the colors on your Android device based on the position of the sun, or your custom configuration. When using the default settings, your display will get a warmer tint (lower color temperature) when the sun is down, vastly reducing strain on the eyes. Blue light makes your brain want to stay awake, and a lower color temperatures reduces the amount of blue displayed; using this in the evening reduces your brain's effort to keep you awake at night. During sleeping hours by default a red filter is used. Red strains your eyes the least, and retains your night vision.

Light sensor The light sensor can be used to automagically adjust the color: switch to the sleep filter in full dark, or to the day filter (usually none) under bright lights. Because light sensor quality varies wildly between devices, a calibration option is provided to experiment with. Color filters Several filters are provided. Those named after a color (red, green, blue, amber, salmon) do not limit the display to those colors, but convert the displayed image to grayscale first, then display that image in levels of the selected color. This preserves details that would otherwise be lost. Grayscale, invert colors, temperature adjustment and custom R/G/B adjustment filters are also provided. Colorblindness The master color filter setting also has an option for colorblindness enhancement, with settings for protanopia/anomaly, deuteranopia/anomaly and tritanopia/anomaly. These options redistribute colors across the spectrum, in theory enhancing clarity and color detail. No claims are made to the effectiveness of these filters, but positive reports have been received from testers. Note that these filters were thought up by Google engineers, CF.lumen just includes them. There is a Pro version of this app as well, which will remove all nags, unlock the option to start at device boot (make sure you test your configuration first), and unlocks notification options. It also enables Tasker integration. In Pro mode, the notification adds convenient buttons to quickly disable the current filter or switch to sleep mode, and you can switch the notification to when enabled mode, which shows the notification only when a color filter is active. If you have rooted your android device, let this app be the bridge between our busy lives and nature. When we do not have any time at all to spend with nature, CF.Lumen lets nature help us!
