I don't do intraday planning, but for TODOs I settled on a A5 paper with handwritten task list. It's very satisfying to strike out completed tasks. From time to time I rewrite pending tasks to new piece of paper. It is a physical reminder of repeatedly uncompledted tasks and somtimes I leave out a thing (I it was not done until now, I can safely not do it at all). Keeps me focused on important things (not to be confused with urgent things).
