Plan your day the way time actually works — in a circle. DayZen is a radial day planner that lays your 24-hour schedule on a beautiful circular clock. See your whole day at a glance, watch the time needle sweep forward in real time, and build a rhythm that sticks. VISUAL PLANNING, REIMAGINED Tasks appear as colored arcs around a 24-hour clock face. The current-time needle moves with the minute, so you always know where you are in the day. No more scrolling lists — just one calm overview. FOUR SMART TASK TYPES • Fixed — pin tasks to exact time slots • Flexible — things you'll fit in whenever it works • Parallel — stack overlapping tasks (a podcast while commuting) • Milestone — deadlines and one-shot moments BUILT-IN ACCOUNTABILITY • "Starting soon" reminders before each task • Check-in notifications when a task ends: Done, Skipped, or Snooze • Subtasks and dependency chains — block a task until prerequisites finish • Daily streak counter to keep your momentum alive APPLE CALENDAR SYNC DayZen creates its own calendar so your existing events stay untouched. Two-way sync means changes flow both ways without surprises. RECURRENCE MADE SIMPLE Repeat daily, on weekdays, on weekends, or weekly — one toggle, no fuss. INSIGHTS & STATISTICS • Weekly category breakdown • Day streak counter • Peak productivity hour • Daily wisdom quotes for motivation DESIGNED FOR FOCUS • Six premium themes — System, Midnight, Ivory, Ocean, Rose, Forest • Clean, minimal UI with full dark mode • Haptic feedback for a tactile, premium feel • Turkish and English with instant in-app switching PRIVACY-FIRST All data is stored locally on your device. No accounts, no sign-ups, no network calls. Your day belongs to you. DAYZEN PRO Unlock unlimited daily tasks, unlimited custom categories, and support continued development. • Pro is offered as an auto-renewing weekly subscription. • Payment is charged to your Apple Account at confirmation of purchase. • Subscription automatically renews unless cancelled at least 24 hours before the end of the current period. • Your account will be charged for renewal within 24 hours prior to the end of the current period. • Manage or cancel anytime in Settings → Apple ID → Subscriptions.

OneThing

OneThing cuts through the ADHD fog and shows you one thing at a time. It's an ADHD focus & task planner. You have tasks in Google Tasks, events in Google Calendar, emails in Gmail, reminders in Apple Reminders, items in Todoist — and a brain that freezes when choosing where to start. OneThing reads all of it, scores by urgency, and hands you a single swipe card: the one thing to do right now. HOW IT WORKS Swipe right to commit and mark done. Swipe left to defer. Swipe up to delete. Swipe down to pin as your Do Now. Each swipe brings the next card — no lists, no overwhelm. WHAT YOU GET • Decision queue that merges calendar events, tasks, and emails into one prioritised stack • AI assistant you can voice-ramble to — it turns your thoughts into tasks and actions • Google Calendar, Google Tasks, and Gmail sync — see your whole day without switching apps • Apple Reminders sync • Todoist sync • Do Now mode: one thing, front and centre, for the next hour BUILT FOR ADHD No lists. No folders. No endless settings. Just one card, one choice, one tap. PRIVACY OneThing reads your calendar events, tasks, and email metadata (subject, sender, date). We never read email bodies without your explicit opt-in. Your data is never sold and never used for advertising.
