MOPSICAL
Focus, energy, and better habits — practical systems for getting your head in the game and keeping it there.
From planning focus sessions and clearing sleep debt to timing your caffeine, budgeting deep work, tracking a habit, and riding your natural energy cycles, Mopsical pairs free hands-on calculators with practical guides on attention, routines, and mental energy. Focus deeper, work calmer.
Focus & Energy Tools
Free tools for a sharper day — a focus-session and Pomodoro planner, sleep-debt calculator, caffeine timing calculator, deep-work budget planner, habit consistency tracker, and ultradian energy-cycle planner.
Focus Session & Pomodoro Planner
Plan a run of focus sessions with short and long breaks — total focus time, break time, the focus ratio, and your finish time.
Sleep Debt Calculator
Add up a week of nightly sleep against what you need — your accumulated debt, nightly average, and how many nights it takes to recover.
Caffeine Timing & Half-Life Calculator
How much caffeine is still in your system at bedtime, how long a dose takes to clear, and the latest you should have that coffee.
Deep Work Time-Budget Planner
Turn desk hours into a realistic weekly deep-work budget — a sensible daily share, capped at a ceiling and split into protected blocks.
Habit Consistency Tracker
Turn days completed and elapsed into an adherence percentage, then see what it takes to hit your target — and whether it's reachable.
Ultradian Energy-Cycle Planner
Fit your day to the body's ~90-minute waves of focus and fatigue — whole focus-then-rest cycles with a scheduled timeline.
The Museum of Focus
Wander an illustrated collection of the science behind a focused mind — attention and cognition, sleep and the body clock, how habits form, and the meditation and focus practices people have used for centuries, each in its own gallery. Every entry, image, and fact is drawn from Wikipedia and Wikimedia Commons.
