Trying to setup obtainium and I’m forgetting just where I got some of my apps from. Does anyone know if I can get a list of all the apps that I’ve installed by repo? This could be just a way to achieve this or an app itself - not too fussed, but I feel updating my foss apps is getting on top of me. Thanks.
In some cases you will need to uninstall/reinstall if you have already installed from another store, like F-Droid. I’m only saying this because I don’t have a good answer to your question, other than to go through app by app. Sorry.
