For years I've used paper and a printed clock to organise my day. Found it way better than any list or timeline app.Played around a bit and made a digital clone to speed things up: Reassign.app (best experience is on desktop)Anyone else think of their day as a circle rather than a list?edit: it also has MCP integration (https://reassign.app/api/mcp) — my Claude already connects to Linear and Calendar, so I use it to start and plan my day. I can quickly get a skeleton of a day out and then polish until done.
