I am one of those people who cannot handle multiple apps that do the same thing. Whether they are for personal or professional use, if both apps are about tasks, then it's really tough for me to use both.
However, I've realized that I can manage multiple apps if they serve very specific, compartmentalized purposes. For example, I want my journal and personal databases to be interconnected, but do I really need my shopping list to be linked up? It serves no purpose being in my PKM app.
Take bookmarks, for instance. It's quite a hassle to have bookmarks in Notion, and I'm considering alternatives like Chrome bookmarks or Raindrop. So, in short, it's all about compartmentalizing your digital life to make things less complicated.
