Ranked in these QuestionsQuestion Ranking
Pro Responsive support
Developer provides prompt and understanding support with problems raised/questions asked.
Pro Advanced scheduling options
Every 2 weeks, then edit four weeks in for 'This and following instances' etc., perfect with Google Calendar.
Pro Multiple flexible widgets
Allows you to customise the look/feel of the widget, even after it has been created. Show different calendar/task accounts per widget.
Pro Multiple Calendar + Multiple Task functionality
Allows you to manage multiple calendars and multiple task (Google) accounts with ease.
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 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 File sizes are shown
For those running out of room, the size of the APK is always shown.
Pro Multiple repository sources
You have more than one source of apps and updates and local repository too
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 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 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 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 Updates are not automatic
You have to click the updates one-by-one in order to make them happen.
