How much does it cost to build an app in Bangkok?

It depends on scope, but a focused mobile app typically starts from around 150,000–300,000 THB, with larger marketplace or platform apps ranging higher. We give you a fixed, itemised quote up front — no hidden costs — so you know exactly what you're paying before we start.

How long does it take to develop a mobile app?

A well-scoped app usually takes 6–14 weeks from kickoff to launch. Because we use an AI-augmented workflow, we ship noticeably faster than a traditional Bangkok agency without cutting corners on quality or testing.

Should I build a native app or a cross-platform one?

If you need both iOS and Android and want to move fast and cost-effectively, React Native or Flutter is usually the right call — one codebase, both platforms. For apps that lean heavily on device hardware or need maximum performance, we build fully native in Swift and Kotlin. We recommend the right approach for your project, not the one that bills the most.

Do you work with clients outside Thailand?

Yes. While we're based in Bangkok, we build apps for clients across Asia, Europe and beyond — including many Swedish and international companies. We work in your timezone and your language.

Can you submit the app to the App Store and Google Play for me?

Absolutely. We handle the full submission process — store listings, screenshots, review requirements and the go-live — and the App Store and Google Play accounts remain yours.

Can you take over an existing app another developer built?

Yes. We regularly rescue and modernise apps started elsewhere. We audit the existing codebase, tell you honestly what's salvageable, and take it forward from there.

Do you integrate Thai payment methods like PromptPay?

Yes. We integrate PromptPay, Thai card gateways and international processors like Stripe, and build with Thailand's PDPA data-protection rules in mind.

Mobile app developers in the heart of Bangkok

TrueDev is an app development company based in Bangkok, building custom mobile apps for Thai brands, hospitality groups, fintech startups and international companies expanding into Southeast Asia. Founded in 1997, we've spent nearly three decades shipping software — and today an AI-augmented workflow lets a small senior team deliver App Store-ready products faster than a traditional Bangkok agency.

Whether you need a customer-facing app on iOS and Android, an internal tool for your field staff, or a marketplace connecting buyers and sellers across Thailand, we own the whole journey: product strategy, UX/UI design, native or React Native development, App Store and Google Play submission, and ongoing maintenance once you're live.

You work directly with the people writing the code — no account managers, no offshore handoffs, no specs lost in translation. Meetings happen in Bangkok time, in English, Thai or Swedish, and you own 100% of the source code, designs and data from day one.

Why Bangkok businesses choose TrueDev for app development

A senior team, AI-accelerated delivery, and full ownership of everything we build.

Ship faster, spend less

AI-augmented development lets us deliver production apps in weeks, not quarters — at a fraction of what enterprise agencies in Bangkok charge, with no compromise on quality.

Native-grade performance

Swift, Kotlin and React Native apps built for smooth 60fps experiences, offline support and battery efficiency on the devices your Thai customers actually use.

Design that converts

Every screen is crafted by people who care about UX — onboarding that doesn't lose users and interfaces tuned for Thai and international audiences alike.

Built to last

Clean architecture, automated tests and CI/CD pipelines, so your app keeps working through every iOS and Android update long after launch.

One team, end to end

Strategy, design, development, store submission and support under one roof in Bangkok — a single point of accountability.

You own everything

Source code, design files, App Store accounts and data are yours from day one. No lock-in, no hostage situations.

Native & cross-platform

Apps your customers actually keep on their home screen

We sweat the details most agencies skip — fast launch, smooth gestures, offline support and a design language that feels right at home on both iOS and Android.
