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. You schedule 10 pounds of work into a 5-pound day, and then feel guilty when you don’t finish. 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. WHY THIS IS THE ULTIMATE ADHD PLANNER For the ADHD brain, time is abstract. DayZen makes time concrete. CONQUER ADHD TIME BLINDNESS Don't just read your schedule: see your time. DayZen acts as a visual timer and planner to fix time blindness. Drag and drop tasks onto the clock face and resize them with a finger. Conflicts glow red instantly so you can fix your daily routine before the day starts. INTUITIVE TIME BLOCKING Forget rigid spreadsheets that kill dopamine. Simply drag a slice of time to create a task. It’s the fastest, most tactile way to build a daily schedule using the time blocking method. STAY ON TRACK WITH WIDGETS Keep your visual day at a glance. Our beautiful Home Screen widgets show your current time block and what’s coming next to prevent executive dysfunction. SYNC WITH REALITY Seamlessly integrates with your Apple Calendar. Your meetings, classes, and time blocks live in one unified visual circle. BUILD BETTER HABITS Set recurring tasks once (e.g., "Morning Meds" or "Deep Work") and let DayZen protect that time forever.

Experience the difference of visual time management. - Premium: Unlock unlimited tasks, advanced time statistics, two-way calendar sync, and Dynamic Island support. THE REAL DIFFERENCE Other planner apps ask, "What do you want to do?" DayZen asks, "What time actually fits?" See the circle. Respect the clock. Own your day.

About

SelfMastery 30

Features
Read full description

SelfMastery gives you one meaningful goal and thirty days to move toward it. Not another habit tracker asking what you want to track. SelfMastery asks what you want to change - then works out what you should do today. CHOOSE ONE GOAL Study more consistently. Become more active. Find a better job. Take control of your money. Spend real time with your family. Read again. Finish the thing you keep restarting. Or describe something in your own words. GET A PLAN THAT FITS YOUR ACTUAL LIFE Answer a few questions - how much time you genuinely have, what usually gets in your way, when you're most likely to act - and SelfMastery builds thirty days of small, specific actions. Week one is deliberately easy. The plan grows only once showing up has stopped being a decision. KNOW WHAT TO DO TODAY Open the app and see today's actions. Nothing else competes for attention. Tick them off as you go. MINIMUM DAY Some days fall apart. Instead of skipping, switch to a Minimum Day: the same commitment at its smallest size. A thirty-minute walk becomes five minutes. Reduce the requirement, not the commitment. REFLECT IN SECONDS One tap to say how the day felt. A note if you want one. Nothing longer. ADJUST EVERY WEEK Every seven days you look back for two minutes. If the week was hard, next week gets lighter - SelfMastery never responds to a difficult week by asking for more. Days you've already completed are never rewritten, and every change to your plan comes with the reason for it. SEE WHAT YOU ACTUALLY DID Your calendar, your consistency, and observations drawn from your own record - never invented. On Day 30, what changed, in your words and in real numbers. BUILT TO BE CALM No streak warnings. No guilt. No badges or confetti. A missed day isn't a failure, and the app never tells you it is. SelfMastery is for anyone with something they've been meaning to change.
