Fixed schedules assume a fixed life. StudyHubs' planner rebuilds itself around what actually happened yesterday.
Most study planners are built like a train schedule: fixed stops, fixed times, and a quiet assumption that you'll show up exactly as planned. Real weeks don't work that way, and pretending otherwise is why so many study plans get abandoned by Wednesday.
Plans that bend instead of break
When a session gets missed, the planner doesn't just guilt you into cramming it back in — it re-spreads the material across the days you actually have left before the thing that matters (a test, a deadline, a presentation).
It also pays attention to which topics you're moving through quickly and which ones keep resurfacing. The second kind gets more spaced repetition automatically, without you having to notice the pattern yourself.
