Alternative app store

App store Description
F-Droid review F-Droid If you are the proud owner of an Android phone (including CalyxOS or LineageOS), have a look at F-Droid! It's a Google Play Store alternative exclusively hosting free and open-source applications. Installing and keeping F-Droid up to date should be pretty straight forward. More detailed instructions below.
Aurora store apk Aurora Not all useful Android apps are FOSS, tracker-free or available on F-Droid. That doesn't necessarily mean they are bad for your privacy. It also doesn't mean you have to use Google's Play Store to get them. Install the Aurora store apk instead, an alternative app store where you can download, update or search for apps without a Google account.
Download Android marketplace Fossdroid Android market place similar to F-Droid, promoting free and open source apps on the Android platform.

Can I install F-Droid or FOSS apps on my iPhone?

Owners of iOS devices are out of luck. Apple's walled garden makes it practically incompatible with mobile FOSS apps. Under the pretext of security, Apple's use of copyright lock and access control forecloses any tinkering, jail-breaking, repairing or diagnosis on iOS devices. Apple — not the user — gets to decide what content can be accessed, what apps can be installed and when the device needs to be thrown away.
