What's that plane flying above me?

When you hear the sound of an aircraft flying in the sky, have you ever wondered... "What type of aircraft is it? Where is it flying to?"

If yes, this app is for you. It answers that exact question.

You can scan the sky manually by pressing the Search button or let the app auto-detect flights when it hears the sound of aircrafts. It uses AI sound classification models to achieve that.

Designed with privacy protection in mind.

Lunar Calendar Event Generator

Google Calendar/Microsoft Outlook does not allow us to create recurring events based on lunar calendar (e.g. grandparents' birthdays, mid-autumn festivals)

This little web site generates an calendar import file (.ics) for your selected lunar events for the coming 60 years.

You can then import the generated .ics file into Google Calendar/Outlook /iPhone Calendar so it's easy to remember when to call/visit them on their birthdays 🎂
