My wife did the same on signal. When I showed her the "Note to self" feature she was amazed an. started using it. She use to get annoyed that we would text and her note would get lost but now it doesn't.
It isn't about finding the best, it is about finding better than the worst. My wife needs the features Obsidian has, she says she wished her notes would visually link together. What she doesn't know is that such apps exist.
She wishes she could sync files between her phone and computer and not have to go to a website to get them. syncthing does that.
