Top 20 free open source apps for Android

Android is an open source operating system, meaning that the Android software code can be used by other developers and can also be modified.
Le app Open Source they are appreciable and preferable over the others because they are not born for commercial reasons, because they do not have a company behind that earns money from their use (at least not directly), because they have no advertising, why respect privacy and why they are free to be used for free without limitations, even for commercial purposes.
While we have seen, in another article, the best open source programs for PC, on this occasion we discover the 20 best open source apps for Android that you can download both from the Google Play store, both from another store called F-Droid, who specializes in listing only and exclusively open source applications.
Theoretically, using all these apps to carry out the main tasks of the phone, you can really boast of having a cell phone almost completely made of open source software.

1) DuckDuckGO is the app to search the internet while protecting privacy in a private way, without searches being tracked and recorded to be exploited for advertising purposes as Google does.

2) Muzei is the best app to have a different wallpaper every day on Android to which I have dedicated a specific article in the past. Thanks to the fact that it is open source there are numerous plugins and extensions that can be added to Muzei to make sure that the selection of wallpapers comes from different sources such as Instagram, Flickr and the NASA website.
