Ranked in these QuestionsQuestion Ranking
Pro All titles are free and open source
All apps and games on F-Droid are free and open source (FOSS), making for a complete store resource for users who want to use only open source software on their device.
Pro F-Droid compiles all packages
F-Droid compiles all the packages themselves ensuring a high level of security. Other stores just allow the developer to upload the app already compiled, meaning anything malicious could be in the app.
Pro All apps have no ads nor tracking
This alone can be a great reason to use the apps available on F-Droid, but there is also the fact that this can increase battery life due to tracking and ads never requiring a data connection, since they are not present.
Pro File sizes are shown
For those running out of room, the size of the APK is always shown.
Pro Previous versions of apps remain available after updates
If you don't like an app after an update, you can download the previous version again. This is not possible on GooglePlay.
Pro Multiple repository sources
You have more than one source of apps and updates and local repository too
Pro Ability to get old version of an app
If the current app doesn't work correctly, users can seek an older version of the app by finding it and downloading through APKMirror.
Pro Many popular apps available
There are many popular apps on APKMirror that are also available on the Google Play Store which are contributed by the community. There is a strict check of the app when any user or developer wants to upload the app to the website to ensure that the app is same as on the Google Play Store.
Pro No account needed
There is no account creation required, so anyone can freely download the app directly from the website.
Apkmirror is run by the people behind Android Police, one of the biggest android news sites. All apps are manually vetted and aproved.
Pro Get access to early alpha / beta version of apps
The website also hosts many early alpha / beta versions of apps, so that anyone can access the beta app without needing to wait to become a beta tester.
Pro Modern war source for all your favorite developers
Modern war source is an open-source code for online gaming and program developing, which can help to minimize the effort of making an online compatible game.
Con No ratings/comments/number of downloads
All apps are presented equally. It is difficult to judge an app's quality/popularity before trying it. On the upside, descriptions are fair (written by the F-Droid maintainers, not by the app authors).
Con Small selection
F-Droid has a small selection of apps when compared to other major Android markets. This is due to every app being open source and given away for free, something not many people are willing to do with their time and creations.
Con Not all apps have screenshots
It can be difficult to tell what an app is like without installing it.
Con It doesn't have all the open source apps
There are many open source apps that aren't available on F-Droid due to their authors not making it available on that particular app store. One example is Omni Noted, which is on the Play Store but not F-Droid.
Con Updates are not automatic for non root users
You have to click the updates one-by-one in order to make them happen. If user has rooted their device automatic updates are possible, the app needs to be converted to a system app.
Con Descriptions are only available in English
Though the store app is multilingual, the app descriptions are only in English, meaning you must know English to find an app, even if the app is supposed to be multilingual.
Con A lot of apps lack polish
Since every app on F-Droid is FOSS and released for free, many of them aren't as polished compared to other markets and their paid app selections.
Con No native Android store app
APKMirror only comes as a website and does not have their own Android store app, thus users will need to download the app through the website and then sideload their app manually (requires activation of sideloading on ones device, this can be done by going to Settings > Security > Allow Unknown Sources).
