I was about to install PixelFed, listed in Google Play as a 13-MB app, but it demanded to delete apps before I free 500 MB. Similar thing happens with F-Droid, although it gives less data. Why? Does it not, like Flatpak on PC, list dependencies? But that’s dumb; plus, no dependency for a browsing app may take 500 MB of space, and the demands aren’t getting smaller when more apps are on device.
