Timefuel: The only planner built on chronotype science.
Every other task app schedules by time. Timefuel schedules by energy — the only planner that respects the science of when your brain actually works best.
The science is clear: Research on circadian rhythms shows that cognitive performance peaks at specific times of day, and those times are different for every person. A night owl forcing themselves into a 9am focus session isn't lazy — they're fighting biology. Chronotype researcher Dr. Till Roenneberg found that ignoring your natural rhythm costs productivity and wellbeing. Timefuel doesn't ignore it. It builds around it.
Here's what makes Timefuel genuinely different:
Tag each task by how demanding it is — Light, Normal, or Demanding. Tell Timefuel when you're naturally sharpest. The planner does one thing no other app does: it respects your rhythm. Demanding work lands in your peak hours. Light tasks fill the valleys. Your schedule matches your biology, not a productivity guru's ideal day.
See the whole picture. A stunning 24-hour Planner Clock maps your tasks, sleep, work blocks, and peak hours in one visual. No other planner shows you this. The centre tells you your real free time — not clock time, but time you're actually available after sleep and work.
Make it realistic. Plan My Day arranges your tasks automatically, respecting energy, urgency, and time. Fit Check tells you plainly: will this actually happen? And will your three main goals — the things that define a successful day — survive contact with reality?
Organize without burnout. Today/Backlog split keeps your active list sane when you're juggling dozens or hundreds of tasks. Filter by tags, batch by energy level, focus on what matters.
Your data is yours. All tasks, projects, and settings stay on your device. Nothing leaves, nothing is tracked.
Timefuel isn't another task manager. It's the first planner built on the science of when you work best, not how much you can fit.
