## What is ITD?

A study timer where you focus with friends and your character Dudu grows with every minute.
Block distracting apps and keep your to-dos and study time in one place.

■ Focus timer with Dudu
Dudu grows a little every day based on how long you focus.
Choose a simple timer or Pomodoro, whichever fits your style.

■ Focus is easier with friends
Create a study group and see in real time who's focusing right now.
Cheer each other on with group rankings and stay focused longer.

■ No more distractions
Focus mode uses Screen Time to block distracting apps.
Nothing left but you and your goal.

■ Dress up your own Dudu
Collect star pieces by focusing and checking in, then use them to dress up Dudu.

■ To-dos at a glance
Plan your day and check things off one by one.
Home and Lock Screen widgets let you see your to-dos without opening the app.

■ See your growth in data
Your focus records add up and show how far you've come.

Today's focus becomes tomorrow's growth.
Make every focused minute count with ITD!
