Diadu Now testing on iPhone, iPad & Mac

A planner that meets your mind where it is.

Diadu is a neurodivergent-first daily planner. Uncluttered display, honest structure, and a day set up the way you want it.

🔒 No account. No ads. Nothing collected.

Morning, Afternoon, and Evening, laid out as three honest bands.

How it works

The day broken into three clear bands.

1
Diadu Overview showing anchor events
Start of Day · Noon · Bed Time

Start with your anchors.

Three anchor points hold the shape of your day automatically, so you're never staring at a blank grid trying to invent one.

2
Diadu Timeline view in dark mode
Timeline · Overview · Present

View your day the way you want.

Same day, three views. Switch between them any time, choose your color palette Cool or Warm. Dark mode always an option. Nothing you've planned changes when the view does.

3
Diadu Routines list
Events · Plans · Things

Add to your calendar with variety.

An Event with a set time, a Plan for when you need to do it at some point in the day, or a Thing for when you aren't sure where on your day to put it. Plan ahead by making a Routine once, then drop it into any day in a tap.

Use cases

However your day is put together, Diadu holds it.

🌅

Morning routines

Save the steps you repeat each morning and drop them into any day in one tap.

🎯

Break down your event, or plan, with sub-tasks

Don't forget anything you need to get done. List out sub-tasks to keep track of your progress.

🎬

Family time

Plan around people, not just hours. Movie night sits next to Bed Time, not buried in a list.

📅

Appointments

Add an Event with a clock time, and it syncs to your calendar as soon as you save it.

💡

Ideas for later

Drop something into Things when it isn't ready for a time slot yet.

🌙

Winding down

Bed Time closes every day the same way, so the evening never sneaks up on you.

F.A.Q

Questions before you join

Does Diadu collect any of my data?+

No. There is no Diadu server your calendar is going to. Everything stays on your device and in your own iCloud, never Diadu's. The only thing we have is the default info Apple sends when someone Gets the app.

Do I need the TestFlight app?+

Yes. Install TestFlight from the App Store first, then use your invite to install Diadu once it arrives.

Is testing free?+

Yes definitely!

Which devices does Diadu run on?+

The Apple ecosystem of iPhone, iPad, and Mac.

Can I switch Cool, and Warm colors? What about Dark mode?+

Yes, any time in Settings.

Can I use my existing calendar with Diadu?+

Yes. Diadu syncs both ways with your selected iCloud calendar.

What happens to the feedback I send?+

Every note sent through TestFlight's Feedback button goes straight to the person building Diadu.

What if I find a bug?+

Use the Feedback button in TestFlight with a screenshot if you can with your description.
