Phương.

Hi, I'm Phương.

I'm an independent developer in Vietnam. I build small iPhone apps on my own — the code, the drawings, the store listing and the replies to your email — and publish them on the App Store.

Apps

Chaeuni

iPhone

Story text design. Your text, your photos and your dates become a PNG with a transparent background — copy it, paste it into an Instagram Story, put it wherever you like. Korean handwriting fonts, templates with real layers, stickers and kaomoji.

  • Korean first
  • No accounts
  • Works offline

Catnap

iPhone

A focus app. You focus, a cat sleeps. The front camera checks whether you are still at your desk — on your device, never uploaded — and the cat twitches when you drift off, wakes up if you stay away, and settles again when you come back.

  • Vietnamese first
  • On-device camera
  • Works without the camera too

How I build

One app, one job

Each app does a single thing well instead of growing into a suite. If a feature belongs to a different app, it goes in a different app.

Your phone is where your data lives

No sign-up, no account, no profile. Photos, text and sessions stay on your device, and I never receive them.

No ads, ever

There is no ad network, no IDFA and no tracking between apps. The apps are free to use, and a one-time or subscription Pro unlocks the extras.

One language first, then the rest

Chaeuni was drawn around how Korean looks on screen; Catnap speaks Vietnamese before anything else. Getting one language right beats translating five badly.
