One family calendar, every screen

Grandma’s death anniversary falls on the 15th of the 9th lunar month, a different solar date every year. One aunt lives in Saigon, a cousin is in Melbourne, and the person who usually remembers is busy that week.

Nhat Nguyet was built so that nobody in the family misses it.

One reminder, the whole family

Add the date once, in lunar terms. Everyone in the family group gets it at the same time, wherever they are:

• Phone: a notification a month, a week and a day before. App Store · Google Play

• Tablet: the plan for the day: who buys the offerings, who drives Grandma, which prayer to read. Same app, on iPad and Android tablets.

• Web: nhatnguyet.org, for relatives who never install apps.

• Watch: Apple Watch and Wear OS show today’s lunar date, the auspicious hours and the family’s next dates. They install together with the phone app.

• Widget: on the home screen, no need to open anything. Add it from your phone’s widget list after installing.

• Telegram: a short daily brief for anyone who prefers chat over apps. Connect it under Account → Connect Telegram.
