STOP LYING TO YOUR CALENDAR. To-do lists feel infinite. If you have ADHD, lists are just a source of anxiety. You keep adding tasks, but reality keeps disagreeing.

DayZen: Visual Time Planner transforms your daily schedule from a stressful list into a logical 24-hour visual clock. Tasks become colored arcs. When the circle fills, it’s full. No more pretending a 3-hour project fits into a 30-minute gap. It is the ADHD planner that finally works. Design your time. See your visual schedule. Find your focus. WHAT’S NEW IN VERSION 2.0 We’ve rebuilt DayZen to be the ultimate time management companion for the neurodivergent mind. - Live Activities & Dynamic Island: Track your active focus time, remaining duration, and progress without unlocking your phone. - Immersive Focus Mode: A full-screen focus timer designed to eliminate ADHD distractions, complete with haptic feedback. - Deep Insights: Analyze your time usage patterns with new interactive charts for daily, weekly, and yearly trends.
