The term “open-source” was coined by the Open Source Initiative (OSI) in 1998. Its main advantage is that a code, program, or application can be inspected, modified, and improved by any user. This assures us that bugs will be fixed and that there will possibly be improvements in the operation of the programs.

Although Android is an open-source system, and most of the apps developed for it are free, not all are open-source. Needless to say, although not as popular, they are just as useful —and some even more so than proprietary apps—.

So that you can see for yourself the advantages of this type of apps, we have selected the 10 best open-source apps for Android.


Kodi is undoubtedly one of the most complete multimedia file management systems. This tool can turn your phone into a multimedia center to play videos, music files, and photos.

Kodi has a clean and intuitive interface, but the best thing is that it allows you to add add-ons —there are many categories— to further enhance your user experience. For example, you can watch hundreds of TV channels on Kodi or connect to services such as Plex, SoundCloud, or YouTube. [Download]

Telegram is the biggest rival WhatsApp has right now. Although it still has a long way to go to catch up in terms of number of users, the open-source messaging app offers many more options than Meta’s service.

For example, with Telegram, you can edit messages, delete entire chats for both you and the other person, and create channels and secret chats. But that’s not all. Telegram does not rely on the cell phone for its web version. It can also be used on multiple devices simultaneously. [Download]

Among some of Brave’s outstanding features are:

Signal is an instant messaging application developed by Open Whisper Systems to guarantee users secure and private communication. The application allows you to write to someone anonymously— furthermore, backups are kept on the platform’s servers, not in the cloud.

It is also possible to hide your IP address in calls and video calls by redirecting them to the app’s server and blur faces in images directly from the app. [Download]
