ADHD Calendar is a visual day planner for brains that need clarity, not clutter. Build routines on a colorful board, link time blocks and tasks, then follow one calm Today timeline. Perfect for daily scheduling, morning routines, checklists, and executive-function-friendly planning — without the guilt-trip calendar vibe. WHY PEOPLE USE ADHD CALENDAR • Visual plan board — drag, place, and link bubbles into chains and routines • Today timeline — one view for what’s next, what’s done, and what can wait • Time blocks & tasks — schedule your day in beats that feel doable • Focus blocks & brain dump — capture ideas without losing the thread • Energy check-in — quick daily pulse (1–5) without overwhelm • Fun focus nudges — dice roll, lucky codes, and playful prompts when you need a push • Gentle reminders — optional notifications for linked plan items (you choose) • Guest mode or sign in — start in seconds; cloud sync when you want BUILT FOR ADHD BRAINS • Low-friction setup — add a bubble, pick a type, link it, move on • Colorful, high-contrast design — clarity at a glance • Spatial planning — build your day the way you think, not only in lists • Room for rest, transitions, and wins — not just “productivity theater” HOW IT WORKS 1.
