A plain to-do list has one blind spot: it tells you what to do but says nothing about when, so a 12-item list cheerfully pretends all 12 fit into a day they never will. Time blocking is the fix — you give tasks actual slots in the day, which forces the honest question a list lets you dodge: does this even fit?
The two work best together: a to-do list to capture and prioritise, then blocking to place the day's few important ones into real time. This tool handles the capture-and-prioritise half (Today / This Week / Someday), so you're blocking a sane shortlist, not a fantasy. Just try it — get the list honest first, then block the two or three that actually matter today.
