What’s this APP

LetJoyIn 喜事入 is a gentle, private iOS app that helps you capture and treasure your joyful moments, like glowing notes kept safe in a bottle.

It doesn’t manipulate, compete, or pressure.
It’s a space where joys are treated with care.
It doesn’t demand your time, but offers peace whenever you give it.

Your privacy comes first: there’s no cloud connection, no account, no tracking. All your joys live safely on your phone, and only you can see them.

Most of us aren’t short on happy moments, we’re just short on noticing them.
LetJoyIn isn’t only about recording joys; it’s about gently shifting your focus away from negative noise and toward what truly matters.

Why this APP

LetJoyIn 喜事入 began as a small section on my personal website five years ago, created to capture little moments of joy. I used to designed a LetJoyIn T-shirt and sent it to friends, and years later, seeing one of friends wear it to dinner, which made me feel proud.

And, my wife’s constant encouragement kept the idea alive.

One day, while waiting for a train at Shanghai Hongqiao Railway Station, watching people come and go, I don’t know why, but just thought it was time to finally make the app.
