Show HN: built a 24h-clock based radial planner to help with ADHD time blindness

Hey HN,
I built DayZen because of the struggle I had with my ADHD and time management.
The core idea: Show your day as a 24-hour radial clock. Tasks become colored arcs around the circle. When the circle fills up, it's full.
How it works:
Drag tasks onto the clock face and resize them with your finger Overlapping tasks glow red immediately (no more finding conflicts at 11 PM) Two-way calendar sync keeps everything in one place Widgets show your current task and what's next
What makes it different: Most planners ask "what should I do?" DayZen asks "what actually fits?" It's not about motivation, it's about physics. You can't fit 10 pounds into a 5-pound bag.
I originally made this for my ADHD brain, which has zero time awareness. Turns out the visual approach helps anyone who thinks spatially or chronically overschedulules.
Tech stack: Native iOS (Swift/SwiftUI), local-first with optional iCloud sync, zero tracking or accounts required.
The app is live on the App Store now.
Happy to answer questions about the approach, technical choices, or why I thought a radial interface would work when every other planner uses lists.
