I’ve procrastinated. A lot. So I built the tool I needed: a calendar that nudges me to start and makes each tiny action feel rewarding. Why it works • On-screen triggers. Start right from Lock Screen, Home widgets, or Dynamic Island—no app hunting, no friction. • Visual, not vague. See time as colorful blocks; watch empty gaps shrink as your day fills up. • Micro-wins. Pre-set 5/10/15/20/30/40-minute sessions make “just start” effortless. • Behavior cues. I researched what actually helps: clear next step + visible progress bar = momentum. What I do with it • Tap a tile (Code, Deep Work, Gym, Cleaning, Cooking… you choose) → timer starts → progress shows on Lock Screen. • Quick-log board for instant actions; no typing, no setup. • Day / Week / Month / List views to plan and review at a glance. • Color-coded categories keep context obvious and motivating. • Smart reminders surface the right nudge at the right time. Designed for humans • Gentle, friendly UI—high contrast, readable, and calm. • Built for short bursts or deep focus. • Feels like a game of filling your day, not a chore list. Perfect if you • Want an anti-procrastination calendar that actually gets you to start. • Love time-blocking but hate friction. • Believe small habits create big change. I finally found a way that sticks. If you’ve struggled like me, try filling just one block—then another. Your day will take care of itself.
