Scan a code, or make one
Point the camera at a code and it reads. Going the other way, make your own for a link or any bit of text you want on a poster.
Point the camera, get the link. Build your own codes in your own colors. Free, and nothing leaves your phone.

Seven things, all free. There's no paid tier holding the good ones back.
Point the camera at a code and it reads. Going the other way, make your own for a link or any bit of text you want on a poster.
Change the colors and the module shape, then drop your logo in the middle. It still scans.
Every code you scan or create is saved, so the link you forgot to write down is still there tomorrow.
Dark mode for reading a menu in a dim restaurant. Light mode for everywhere else.
A short buzz and a beep when a code lands, so you know it worked without watching the screen.
The whole interface is translated, not just the menus. Set it once in settings.
The camera opens on launch. Everything else is one tap from there.
This is what it actually looks like on a phone.

VNDev Labs is a small mobile team in Vietnam.
We build utilities: the kind of app you install once and never think about again. Launch time and battery matter more to us than shipping a new feature every sprint.

We make small Android and iOS apps. No funding, no roadmap deck, no growth team.
An app should do its one job and then get out of the way. Most of the work is deciding what to leave out.
We'd rather ship something narrow that works than something broad that mostly works.
The four-star ones are in here too.
If the app has been useful, a review helps more than you'd think.
Free on Google Play and the App Store. No account, no subscription, and your scan history stays on your phone.
Bug reports get read first. Feature requests get read second.
