About this app

That friend you finally caught up with — where did you two eat last year?
Your colleague's oldest daughter. You knew her name once. What was it again?
Your partner's birthday is coming up. What did you give them last time?
What was your director into, again?

And that note you swore you'd never lose — where did it go?

We all have people worth looking after.
And somehow, they're the easiest thing to let slip.

That's why DDU DDU exists — the simplest way to take care of yourself and the people around you.
Every memory tied to the people in your life, brought back to you right when it matters.

"Lunch with Arang, July 28 at 2:00 PM. She's been deep into running lately."
"Meeting with your partner company's CEO tomorrow at 4:30 PM. You noted their second child was just born."
"You said you'd call Mom this weekend. You wrote down 'knee' — maybe ask how it's doing."

Add the people to your plans, and DDU DDU keeps their story up to date and reminds you at the right moment.
Writing it down, made effortless

Other calendars: tap the date, set the time, pick a category, choose a tag… and give up halfway through.

DDU DDU takes one line — date, time, who, what — in any order, exactly as it comes to mind. The AI sorts it out and files it for you.

"Dinner with Arang next Tuesday at 7pm for her birthday" works.
"7pm arang birthday tuesday next week dinner" works just as well :)

Write it like a note. DDU DDU turns it into a plan — and remembers the people in it.

■ One line in, done No forms, no fields. Just type. Date, time, and who you're seeing are picked up automatically.

■ A calendar that remembers people Anyone who appears in your plans is saved automatically.
Leave notes about them, and DDU DDU brings those notes back the next time you meet.

■ Today's Care Everything you've noted about the people you're seeing today, in one glance. Every meeting gets a little warmer.

■ Gifts & places Keep track of what you gave, and where you went together.

Not a tool for managing schedules. A friend who remembers your relationships.
That's DDU DDU. Shall we?
Jot it down, we'll organize it, AI that remembers your people
