About Diadu - ADHD Friendly Calendar
Meet your day where it is. Diadu is a neurodivergent-first daily planner that gives your day clear structure without filling the screen with clutter. Morning, Afternoon, and Evening bands make time easier to see, while three focused views let you choose the amount of detail you need right now. PLAN WITH THE RIGHT KIND OF ITEM • Events have a specific time. • Plans belong to a part of the day without needing an exact time. • Things hold ideas and tasks that are not ready to schedule yet. BUILD A DAY THAT WORKS FOR YOU • Shape each day around Start of Day, Noon, and Bed Time anchors. • Switch between Overview, Timeline, and Present views. • Break events and plans into smaller subtasks. • Save repeatable routines and add them to a day in one tap. • Choose warm or cool colors and use light or dark mode. BUILT ON APPLE CALENDAR Everything you schedule in Diadu is a real event in your Apple Calendar, so it shows up on your iPhone, iPad, Mac, and Apple Watch without a second copy to keep in step. Choose which calendars Diadu shows, pick the one new items go to, and see each item carry its calendar's color so work, home, and family stay easy to tell apart. Share a calendar with family or friends the normal way, in Apple's Calendar app. PRIVATE BY DESIGN Your events stay in your own Apple Calendar. Your Things, routines, settings, and per-item details stay in a single file in your private iCloud Drive. Diadu has no account, no advertising, no tracking, and no server that reads your calendar. Notifications are scheduled locally on your device. Diadu is available for iPhone, iPad, and Mac. Plan your day, your way.
What’s new
Version 2.0 · Updated September 19, 2026
Tested on iPhone 18 Pro iOS 27.0 build 29. Attachment is Diadu-test-v2.0. Diadu 2.0 is built on Apple Calendar. Your events and plans now live directly in your Apple Calendar, so everything you schedule in Diadu shows up wherever you already look, on iPhone, iPad, Mac, and Apple Watch. There is no second copy of your day to fall out of step. WHAT IS NEW • Events and Plans are real Calendar events. Edit them in Diadu or in Calendar. • Choose which calendars Diadu shows, and set the one new items are added to. • Each item carries its calendar's color on the card, so work, home, and family stay easy to tell apart. • Subtasks, bands, done state, and per-item reminders stay private to Diadu, and sync through iCloud Drive along with your Things, routines, and settings. • Widgets, Siri, notifications, and end-of-day rollover all read the same calendar data. MOVING YOUR DATA If you have been using Diadu 1.x, a guided migration copies your events, plans, Things, and routines into the Apple calendars you choose. Diadu shows a notice once when there is data waiting, and you start the move when you are ready, from that notice or from Settings. It verifies every item before counting it, it never deletes anything from your old data, and you can run it again later. ALSO CHANGED • Diadu now requires access to your calendars. • Diadu's own sharing has been replaced by Apple Calendar sharing, set up in the Calendar app. Calendars you had shared from Diadu need sharing again there. • Importing .ics files has been removed for now. Thank you for planning with Diadu.
