## What is Happy K?

You've been alive for thousands of days. Someone you love is about to hit a perfectly round number of them. That's a k-day — and it deserves cake.

KDay reads birthdays from your contacts and counts down to everyone's next 1000-day milestone. A newborn hits 1,000 days at about age three. You'll pass 10,000 around your 27th birthday. Your mother might be days away from 25,000 right now — and nobody knows.

WHO'S NEXT
The very next k-day in your life, front and center, with a progress ring filling as the day approaches. Everyone else lines up behind it.

NEVER MISS ONE
A notification on the day itself, plus a heads-up in advance (you pick how far ahead — enough time to plan something).

MAKE IT A MOMENT
Share a beautiful milestone card ("25,000 days on Earth") to WhatsApp or Instagram. Full-screen confetti when a k-day is today. Fun facts with every milestone — 20,000 days is about 2.8 billion heartbeats.

YOUR OWN COUNTER
See exactly how many days you've been alive, live, and when your next round thousand lands.

A WIDGET WORTH THE SPOT
The next k-day on your home screen, updating itself daily.

EVERY WAY TO ADD PEOPLE
Contacts, manual entries, calendar import, or ask someone directly with a ready-made message.

PRIVATE BY DESIGN
Everything is computed on your phone. No account, no server, no analytics, no ads. Your contacts never leave your device — the app makes no network requests at all.

In 40 languages. Some birthdays are worth waiting 1,000 days for.
