Duoc Khang Studio is a mobile app studio. We design, build, publish and keep maintaining Android and iOS apps — the whole thing, by the same small team, from the first sketch to the update you ship next month.
Six things have to go right for an app to survive its first year. We do all six ourselves, so none of them falls into a gap between two agencies.
Kotlin on Android, Swift on iOS, or one shared codebase when the product does not need two. We pick per project and tell you why, instead of selling you the stack we happen to like.
We draw every state, not just the happy path — empty, loading, offline, error. That is where apps usually feel cheap, and where a few hours of design save a month of complaints.
Cold start, memory, download size and battery are budgets we set at the start and measure at every build. A slow app is never deleted loudly — it just stops being opened.
Listing text, screenshots, data-safety forms, signing, and the review replies when something gets rejected. We have read the policies so you never find out the hard way.
Crashes get watched, OS releases get handled before they break anything, and the next version is planned from what users actually did — not what we assumed at kick-off.
Your questions reach the person writing the code, usually the same day. No account manager in the middle translating what you meant into a ticket.
New product, an app you inherited, or a team that needs extra hands — the four stages below stay the same either way.
Start a projectWe turn the idea into screens, a feature list and an honest estimate. What is in version one, what waits for version two, and what it costs — agreed before a line of code is written.
Interface design and development run in one- to two-week sprints. You get a working build on your own phone at the end of each one — no three-month silence followed by a surprise.
Testing on real devices, not just simulators. We prepare the store listing, privacy declarations and screenshots, then handle the App Store and Google Play submission and the review back-and-forth.
Crash monitoring, OS version updates and the next round of features. Or a clean handover to your own team, with the repository, documentation and accounts transferred.
“An app is a promise you keep every time someone opens it. Ours are built to survive that test, every single launch.”
We are a small mobile app studio in Ho Chi Minh City. Small enough that the person you speak to wrote the code, structured enough that the build, the release and the updates all land on schedule.
Tell us what it should do and who it is for. We will come back with a scope, a timeline and a price — usually within two working days.
