I try to use mobile web versions saved as an app shortcut. When you install a real app it usually comes with a bunch of permissions needed and trackers collecting your info in the background. Bad for privacy and battery life. Classyshark helps scan the trackers and a firewall can disable wifi access on app by app basis but thats a lot more trouble than just not installing a bunch if junk apps.The exception is that I trust open source software from fdroid with a public github repo.
