iOS app for visual timeboxing with a radial clock interface to help users fight time blindness
DayZen is an iOS visual time-blocking app that uses a 24-hour radial clock interface to help users with time blindness (common in ADHD) plan their day by explicitly scheduling tasks as time blocks instead of infinite to-do lists.
DayZen is a free iOS app that replaces linear to-do lists with a circular, 24-hour radial clock. Users input tasks (with emoji, duration, and category) and see them as colored blocks around the clock. The app outputs a visual schedule that reveals available gaps, plus a focus mode with timer. It is built by developers with ADHD and requires no account — data stays on-device by default.
You open the radial clock showing 24 hours. Tap any time slot to create a task: pick an emoji (e.g., dancing, money bag), set duration, and assign a color category. The block appears on the clock. Tap a block to enter Focus Mode with a timer. Swipe to mark done. No onboarding needed — the app is designed to be operable in 5 taps per task.
DayZen is freemium. The Starter tier is free forever with 10 tasks per day, full radial clock, recurring tasks, and no ads. The DayZen Pro tier costs a one-time payment of $24.99 and includes unlimited tasks and categories, two-way calendar sync, advanced widgets, and priority support. No subscription — pay once, own it forever with all future updates.
Yes, the Starter tier is free forever. It includes the full radial clock view, recurring tasks, and no ads, limited to 10 tasks per day. No time limits or trial periods.
Your schedule stays on your device by default. No account is required, and DayZen does not sell or track your data. Local storage is the default; iCloud sync is optional and only shares between your own devices.
