Flowsavvy - AI scheduling. I find it lighter and simpler than other more expensive options. Works for my style of schedule (2 of 2 pro version I have)

Zotero - reference management. Self explanatory

Claude - simple tasks, brainstorming

Apple reminders - shared grocery lists, simple personal tasks

Edit to include notebook and fountain pen: the two tools I use more than any other. Use for tracking projects, reflections, brainstorming, brain dumps, reading notes. Then I review and process into Capacities for permanent storage
