I use a combination of a TODO.md file shared on all my devices (two laptops, one phone, one VPS) with Syncthing, Google Calendar, and leaving emails/messages unread for external requests. I've tried Notion, Trello, and Keep in the past: they felt over-engineered and too reliant on having an internet connection/browser window open, so in the end I always found myself going back to basics. Haven't had a single problem with my current setup so far.
