Get it on Google Play
Calendar + to-do in one
A monthly calendar with colored category chips and a Today view grouped into Overdue, Today, Next 7 days and Someday. One app instead of two.
Check it off from the widget
The 4×2 Today widget shows today's list with a check circle for each item. Tap to complete — the app never has to open. Three text sizes, dark mode, and a 4×4 month widget with dots on busy days.
Reminders that actually arrive
Morning summary ("3 things today · first: Dentist"), evening nudge, and per-task alarms. Scheduled locally with AlarmManager so they don't pile up after battery optimization. Quiet days get a kind message instead.
No login, no cloud, no subscription
Everything stays on your phone. Export a backup file when you switch phones. Every feature — time, alarm, repeat, categories, holidays — is free with ads.
FAQ
- Is there a calendar app that also works as a to-do list?
- Yes — Dayo shows to-dos on a monthly calendar and in a Today list at the same time. Tap a day to see and add tasks for that date; the Today tab groups what's overdue, due today, due in the next 7 days, and someday.
- Can I check off tasks from the widget without opening the app?
- Yes. The Today widget has a check circle next to each task. Tapping it completes the task immediately and the app and month widget update. The + button in the widget opens the input bar directly.
- Do I need an account?
- No. Dayo has no login, no sign-up and no server. Your data is stored only on your device. Use Settings → Export backup to move to a new phone.
- Does it support repeating tasks like every 3 days or the last day of the month?
- Yes: every day, weekdays, weekly, every N days (every 2, 3, 7, 14 days), monthly on a given day, and last day of month. A task set to the 31st lands on the last day in shorter months instead of disappearing.
- Which countries' holidays are shown?
- Korea, US, Japan, UK, Germany, France, Italy, Spain, Netherlands, Poland, Turkey, Brazil, Mexico, Argentina, Portugal, Indonesia, Vietnam, Thailand, India and Taiwan — offline, no download.
- Is it free?
- Yes. Dayo is free with ads. There is no premium tier; time, alarms, repeats and widgets are all included.
