I noticed that privately and professionally as a coder I am steadily piling up more and more note taking apps in search for the perfect one. Here's a thread
Google Keep https://keep.google.com/ --> as an Android user easy to pick up, ok for quickly writing sth down. Easy to invite other (google) users and have shared notes, for example a grocery list or things like that.
My app is still full of old stuff, which, again, I can probably just quickly go through and delete most of it (but those notes might be uuuuseful some day )
