## What is Cycle?

When did you last replace your water filter?
What about your toothbrush or engine oil?

You don't have to remember everything.
Cycle keeps track of recurring tasks, calculates what's due next, and reminds you when it's time.

■ Set it once

Add an item and choose how often it needs to be done, such as "Replace water filter every 4 months."

Cycle automatically calculates the next due date based on the last time you completed it.

No more trying to remember when you last replaced, cleaned, checked, or serviced something.

■ Get reminded at the right time

Receive a reminder on the due date or choose to be notified 1, 3, or 7 days in advance.

If something is overdue and still hasn't been completed, Cycle reminds you again every morning.

■ Track, complete, repeat

See what's coming up next, ordered by due date.

When you're done, simply tap "Done." Cycle records the completion and automatically starts the next cycle.

Keep a history of completed tasks with notes, organize items into groups like Home, Car, Parents' House, or Pets, and see everything coming up this month on the calendar.

■ Home Screen Widgets (Premium+)

Keep your next 1–4 upcoming items right on your Home Screen.

Choose from small, medium, and large widgets to see what's coming up without opening the app.

■ Add common items faster

Quickly add commonly tracked items such as water filters, engine oil, toothbrushes, bedding, air conditioner cleaning, air purifier filters, pet grooming, and boiler inspections.

Set it once.
Get reminded when it's time.
Tap Done, and Cycle takes care of what's next.

Available in Korean and English.
