Open Source Android Apps


  • LineageOS

    Free Android Android Tablet Website

    A free and open-source operating system for smartphones and tablet computers, based on the Android mobile platform. It is the successor to the highly popular 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.

    LineageOS was officially launched on December 24, 2016, with the source code available on GitHub. Since that time, LineageOS has been described as highly popular and forcibly developed; within 4 months from the initial announcement, LineageOS development builds covered more than 160 models of phone, and over a million users, having doubled its user base in the month February–March 2017.

  • Replicant

    Free Android Website

    Replicant is a distribution of Android that is 100% Free Software.

    Most of Android is licensed freely under the Apache License 2.0. The Linux core is mostly Free Software under the GPLv2. However, there are numerous components of the default software stack on the devices that are proprietary software. Most notably, nearly any component that touches the hardware directly is proprietary software. Replicant lacks location tracking (anti)features.

    On the Replicant Wiki you can find a list of open source apps that can be used to replace the proprietary Google apps (Market, Gmail, Maps, etc.). Most notably, it suggests to use F-Droid instead of Google Market.

  • Aurora Store

    Free Android Android Tablet Website

    Aurora Store is an unofficial, FOSS client to Google's Play Store with an elegant design. Not only does Aurora Store download, update, and search for apps like the Play Store, it also empowers the user with new features.

    For those concerned with privacy, Aurora Store does not require Google's proprietary framework (spyware?) to operate; It works perfectly fine with or without GooglePlayService or MicroG. However, those still reliant on those services are welcome to use Aurora Store as well!

    While Aurora Store was originally based on Sergei Yeriomin's Yalp store, v3.0 is a clean & complete rewrite from scratch that follows Material Design and runs on all devices running Android 5.0+.

  • Shelter

    Free Android Android Tablet F-Droid Website

    Shelter is a Free and Open-Source (FOSS) app that leverages the “Work Profile” feature of Android to provide an isolated space that you can install or clone apps into.

    Shelter comes with absolutely no advertisement / statistics / tracking SDKs bundled with it. All source code is available in at https://git.angry.im/PeterCxy/Shelter or mirror https://github.com/PeterCxy/Shelter and the sources are licensed under WTFPL.

    This app depends on your Android system’s implementation of Work Profile. Some vendor / custom ROMs may have a broken implementation that may cause crashes and even bricking of your device. One such example is MIUI from Xiaomi. I currently provide no support for such ROMs because I personally do not own any of these devices. If you are running Shelter on these ROMs, you are on your own. If any developer out there own these devices and could make Shelter run on these ROMs, please send pull requests and I’ll be happy to merge them.

    Features / Use Cases

    • Run apps inside the isolated profile so they cannot access your data outside the profile
    • “Freeze” (disable) background-heavy or seldom-used apps when you don’t need them. This is especially true if you use apps from "some company".
    • Clone apps to use two accounts on one device

    Caveats

    Shelter is not a full sandbox implementation. It cannot protect you from:

    • Security bugs of the Android system or Linux kernel
    • Backdoors installed in your Android system (so please use an open-source ROM if you are concerned about this)
    • Backdoors installed into the firmwares (no way to work around this)
    • Any other bugs or limitations imposed by the Android system.

    Also, Shelter cannot create more than 1 work profile on one Android device, and cannot co-exist with any other apps that manages a Work Profile. This is due to the limitations of the Android system, and I can do nothing about this.

  • island

    Free Android Website

    What is “Island”
    “Island” is a sandbox environment to clone selected apps and isolate them from accessing your personal data outside the sandbox (including call logs, contacts, photos and etc) even if related permissions are granted. Device-bound data (SMS, IMEI and etc) is still accessible.

    Isolated app can be frozen on demand, with launcher icon vanish and its background behaviors completely blocked.

    How does it work
    Island takes advantage of the “managed profile” feature on Android 5.0+, which is also the base of “Android for Work”, to create an isolated sandbox for apps with their data.

    App needs to be cloned in Island first. Afterwards, the clone can run parallel aside from the original one. (even with different accounts signed-in) It can be frozen on demand by Island. (NO ROOT REQUIRED)

    If Greenify is also installed, apps can be frozen automatically by “Auto-freeze with Greenify” action (in the overflow menu), just like normal app hibernation in Greenify.

    By default Yalp Store connects to Google services using a built-in account, so you do not have to own a Google account to use it. The only reason to use a live Google account is to access the paid apps you own.

    Modern encryption is based on digital “keys”. OpenKeychain stores and manages your keys, and those of the people you communicate with, on your Android.
