Most Maylua apps run 100% on your device — your documents, scans and records stay with you, not on a server.
The Pocket tools and QR Shop charge a single one-time Pro unlock. No monthly fees, no expiring features.
By default our apps need no sign-up and show no ads. Accounts exist only where a service truly needs one.
Every app is designed, built and supported by Maylua itself — support mail is answered by the people who wrote the code.
Public status of the products in the pipeline — the same honesty we put in the apps. Nothing here is downloadable until Google Play approves it or it ships through its own channel.

Maylua Studio is an independent app & web studio based in Vietnam. We build focused tools for the people who keep small businesses running — grocery and repair-shop owners, HVAC technicians, online sellers — and web services like 1Muse and BOO for creators and local shops.
Every product starts from a real workflow we can watch with our own eyes, then gets tested on real devices before it ships. That is slower than chasing trends — and it is why our apps keep working in a basement shop with no signal.
Support for any app, partnership ideas, or just feedback — one inbox, answered by the people who built the products.
