Dayo: Simple Calendar & To-Do

Dayo is a simple calendar and to-do list in one. Add a task in 3 seconds, see your day at a glance, and check it off right from the home screen widget — without opening the app.

No account. No login. No sign-up. Open it and start.

WHY DAYO
• Calendar + to-do list together — one app instead of two
• Home screen widget with one-tap check — today's tasks always in view, big readable text, dark mode
• Time, alarms and repeat are all free
• 100% offline. Your tasks stay on your phone

TODAY VIEW
Overdue, Today, Next 7 days, Someday — grouped so you know what's next. Tap the circle to complete. Done items fold away.

MONTH CALENDAR
A clean monthly calendar with colored category chips, public holidays for 20 countries, and a fast month/year jump. Tap a day to see and add tasks. Long-press to add instantly.

FAST INPUT
A chat-style input bar. Type, pick a date chip (Today / Tomorrow / Someday / any date), set a time, alarm, repeat and category — hit enter and keep typing.

REPEAT THAT ACTUALLY WORKS
Every day, weekdays, weekly, every N days (every 2 days, every 3 days…), monthly on a day, last day of month. Monthly on the 31st lands on the last day in shorter months.

REMINDERS THAT ARRIVE
• Morning summary: "3 things today · first: Dentist"
• Evening nudge: "2 left today — a quick check before bed?"
