About this app

Things that come around, you no longer have to remember.

When did I last change the water filter? How long since the oil change? Toothbrush, bedding, AC cleaning, boiler check, pet grooming. You do it once, forget about it, and only remember long after it was due. Cycle remembers the "last done" and "next due" for you.

■ Three answers and you're set
What it is, how often, and when you last did it. That's all Cycle needs to work out the next due date. Intervals can be any number of days, weeks, months, or years. A monthly cycle started on the 31st lands on the last day of the next month, so you never have to think about the calendar.

■ Everything at a glance
Your cycles are sorted by what's due next. Three states, overdue, today, and left, plus a progress bar show you what to take care of first.

■ Calendar and widget
The monthly calendar shows everything due this month at a glance. The home screen widget shows what's next without opening the app, and D-day counts appear in the list, the detail view and the widget.

■ One tap on Done starts the next cycle
Did it? Tap Done. The completion is logged, the next due date is recalculated, and reminders are rescheduled. Did it a few days ago? Log it on that date instead.

■ We'll tell you when it's time
Get a reminder a few days ahead or on the day itself, and one more nudge if it's three days overdue. Reminders arrive quietly at 9 AM. Tap one to jump straight to that cycle.

■ Sort them into groups
Make groups like Home, Parents' home, or Car and filter the list with a tap.

■ Your history stays, your data stays on your phone
Every completion is kept, so you can look back at when things were done. No account, no server. Everything lives on your device, and you can export it as JSON anytime.

■ Also
- Light and dark themes, or follow the system
- English and Korean
- Archive items you're pausing for a while
