Red Moon is a free software [1] application for the Android operating system, designed to filter blue light from the device's display, helping reduce eye strain during night-time use and disruption of sleep patterns. It allows for independent adjustment of colour temperature, luminosity and filter level, making it also possible to lower the effective screen brightness below the usual minimum brightness level of the device. Red Moon does not require root.
Free software or libre software is computer software distributed under terms that allow users to run the software for any purpose as well as to study, change, and distribute it and any adapted versions. Free software is a matter of liberty, not price: users—individually or in cooperation with computer programmers—are free to do what they want with their copies of a free software regardless of how much is paid to obtain the program. Computer programs are deemed free if they give users ultimate control over the software and, subsequently, over their devices.
Android is a mobile operating system developed by Google. It is based on a modified version of the Linux kernel and other open source software, and is designed primarily for touchscreen mobile devices such as smartphones and tablets. In addition, Google has developed Android TV for televisions, Android Auto for cars, and Wear OS for wearables, each with a specialized user interface. Variants of Android are also used on game consoles, digital cameras, PCs and other electronics.
Current academic and medical consensus suggests there are no known health effects of day-to-day exposure to blue light, and it is not regarded as a cause of eye disease, eye strain, or disruptions to circadian rhythm, as distinct from any other frequency band of visible light. Despite the lack of scientific basis, numerous products and software claim to filter out blue light to prevent eye strain and sleep disruptions. It is illegal in the UK for a health practitioner to indicate to a patient that 400-450 nm blue light causes health effects or affects sleep. Harvard Health continues to support claims that blue light has a stronger negative effect on sleep.
Redshift is an application that adjusts the computer display's color temperature based upon the time of day. The program is free software, and is intended to reduce eye strain as well as insomnia.
Night Shift is a built in software feature of iOS and macOS. It was introduced into iOS in iOS 9.3 and into macOS in macOS Sierra 10.12.4. The feature changes the color temperature of the display towards the yellowish part of the color spectrum that reduces some of the blue light from the screen. Apple claims that the feature may help users have a better night's sleep by filtering blue wavelengths from the display. The feature is similar to the functionality f.lux provides.
The use of computers by children and adolescents before bed has been associated with a reduction in the hours of sleep experienced by frequent users, along with a decreased quality of sleep, in most cases. The results of computer use at night have been linked with tiredness.
F-Droid is a community-maintained software repository for Android, similar to the Google Play store. The main repository, hosted by the project, contains only free libre software apps. Applications can be browsed and installed from the F-Droid website or client app without the need to register for an account. "Anti-Features" such as advertising, user tracking, or dependence on nonfree software are flagged in app descriptions. The website also offers the source code of applications it hosts, as well as the software running the F-Droid server, allowing anyone to set up their own app repository.
Google Play is a digital distribution service operated and developed by Google LLC. It serves as the official app store for the Android operating system, allowing users to browse and download applications developed with the Android software development kit (SDK) and published through Google. Google Play also serves as a digital media store, offering music, books, movies, and television programs. It previously offered Google hardware devices for purchase until the introduction of a separate online hardware retailer, Google Store, on March 11, 2015, and it also offered news publications and magazines before the revamp of Google News on May 15, 2018.

A Linux distribution is an operating system made from a software collection, which is based upon the Linux kernel and, often, a package management system. Linux users usually obtain their operating system by downloading one of the Linux distributions, which are available for a wide variety of systems ranging from embedded devices and personal computers to powerful supercomputers.
KStars is a freely licensed planetarium program using the KDE Platform. It is available for Linux, BSD, MacOS, and Microsoft Windows. A light version of KStars is available for Android devices. It provides an accurate graphical representation of the night sky, from any location on Earth, at any date and time. The display includes up to 100 million stars, 13,000 deep sky objects, constellations from different cultures, all 8 planets, the Sun and Moon, and thousands of comets, asteroids, satellites, and supernovae. It has features to appeal to users of all levels, from informative hypertext articles about astronomy, to robust control of telescopes and CCD cameras, and logging of observations of specific objects.

CSipSimple is a Voice over Internet Protocol (VoIP) application for Google Android operating system using the Session Initiation Protocol (SIP). It is open source and free software released under the GNU General Public License.
Android software development is the process by which new applications are created for devices running the Android operating system. Google states that "Android apps can be written using Kotlin, Java, and C++ languages" using the Android software development kit (SDK), while using other languages is also possible. All non-JVM languages, such as Go, JavaScript, C, C++ or assembly, need the help of JVM language code, that may be supplied by tools, likely with restricted API support. Some programming languages and tools allow cross-platform app support. Third party tools, development environments, and language support have also continued to evolve and expand since the initial SDK was released in 2008. In addition, with major business entities like Walmart, Amazon, and Bank of America eyeing to engage and sell through mobiles, mobile application development is witnessing a transformation.
f.lux is a cross-platform computer program that adjusts a display's color temperature according to location and time of day, offering functional respite for the eyes. The program is designed to reduce eye strain during night-time use, helping to reduce disruption of sleep patterns.

Fuchsia is an open source capability-based operating system currently being developed by Google. It first became known to the public when the project appeared on a self hosted form of git in August 2016 without any official announcement. The source documentation describes the reasoning behind the name as "Pink + Purple == Fuchsia ". In contrast to prior Google-developed operating systems such as Chrome OS and Android, which are based on the Linux kernel, Fuchsia is based on a new microkernel called Zircon, named after the mineral.
LineageOS is a free and open-source operating system for set-top boxes, smartphones and tablet computers, based on the Android Linux distribution. It is the successor to the custom ROM CyanogenMod, from which it was forked in December 2016 when Cyanogen Inc. announced it was discontinuing development and shut down the infrastructure behind the project. Since Cyanogen Inc. retained the rights to the Cyanogen name, the project rebranded its fork as LineageOS.
