a thoughtful use of digital
An useful open source android app to check how (by what apps or data) your device space is used, is Disky.
This “fast storage analyzer creates a pie chart of storage usage and lists folders by size”, very “intuitive and ad-free”.
I.g. yesterday, using this app I noticed that surprisingly an app (LinkToSport) was using 23 Gb. Definitely too much 🙂.
Flatpack has the big advantage that you can a) run apps that couldn’t run the “normal” way (integrated with the system), because of lack of dependencies or b) have automatic updates of apps otherwise upgradable only via ppa or manually.
But its big disadvantage is the space occupied on your hard disk: indeed any app in Flatpack is a “world” in itself, regardless not only of the system, but also other apps in Flatpack itself.
Therefore, be careful to add Flatpack apps, unless you need really them (and them via Flatpack).
