Mobile app development is the process of designing, building and launching applications for iOS and Android — from a first MVP to a fully scaled product. CIT Software builds native and cross-platform mobile apps as a Vietnam-based offshore partner, and hands over the full source code so the app is entirely yours.
What we build
We develop mobile apps across every category businesses actually ship: on-demand and delivery apps, marketplaces, fintech and wallet apps, healthcare and telemedicine, e-learning, booking and scheduling, social platforms, and internal business apps for field teams. Whether you need a consumer product to reach a large audience or an operational tool to replace paperwork, we build it around your users and your workflow rather than a generic template.
Native or cross-platform: choosing the right approach
The right approach depends on your goals, timeline and budget. Native development (Swift for iOS, Kotlin for Android) delivers the best performance and access to device features, and suits apps where speed and polish are critical. Cross-platform frameworks such as Flutter and React Native let you build for both platforms from a single codebase, which cuts cost and time to market while covering the needs of most products. In discovery we recommend the option that fits your case — and if you are weighing it up, our comparison of Flutter vs React Native explains the trade-offs.
Our mobile app development services
CIT covers the full mobile lifecycle so one team can take your app from idea to the store and beyond:
- App strategy & UX/UI design — user flows, wireframes and a clickable prototype you approve before development.
- Native iOS & Android development — high-performance apps built with Swift and Kotlin.
- Cross-platform development — one codebase for both platforms with Flutter or React Native.
- Backend & API development — scalable servers, databases and integrations behind the app.
- Third-party integrations — payments, maps, push notifications, chat and analytics.
- Testing, launch & support — QA, App Store and Google Play submission, and ongoing maintenance.
Need a broader system behind the app? We also provide custom software development for the web platforms and admin tools that support it.
Start with an MVP, then scale
For most new apps, the smartest path is to launch a minimum viable product first — a focused version with the core features that prove the idea with real users. It gets you to market faster, keeps the initial budget under control, and produces real usage data to guide what you build next. From there we expand the app feature by feature based on what users actually do. Our approach to MVP development is built around exactly this: ship the essentials, learn, then grow.
How we build your app
Our process is transparent and iterative. It starts with discovery, where we define the users, features and success criteria; then UX/UI design with a prototype you sign off; then development in short sprints with regular demos so you always see working software; followed by thorough testing across devices and OS versions; and finally store submission, training and source-code handover. After launch we can maintain the app, monitor performance and release new versions on your roadmap.
Technologies we use
We build native apps with Swift (iOS) and Kotlin (Android), and cross-platform apps with Flutter and React Native. On the backend we use Node.js, Python, Java and .NET, deployed on AWS, Google Cloud or Azure, and integrate services like Stripe, Firebase, Google Maps and push notification providers. Because we hand over the source code, your app is never locked to us — any developer can maintain and extend it later.
Why develop your app with an offshore team in Vietnam?
Building your app with a Vietnam-based team gives startups and businesses in the US, Singapore and internationally senior mobile engineering at a fraction of local cost, with English-speaking project management and a strong Asia-Pacific time-zone overlap. Most importantly, you own the source code and the product outright. It is a big part of why more companies are choosing to outsource software development to Vietnam — competitive cost without compromising on quality or control.
App categories we build
We have shipped apps across the categories that drive real business: on-demand and delivery apps with live tracking and payments; marketplaces connecting buyers and providers; fintech, wallet and banking apps with strong security; healthcare and telemedicine apps with booking and records; e-learning apps with lessons and progress tracking; booking and scheduling apps; social and community apps; and internal business apps that put field teams and operations on mobile. Whatever the category, we design around your users and integrate the payments, maps, messaging and analytics the app needs to work in the real world. Many of these apps pair with an AI layer — recommendations, chat or automation — built by our AI development team.
Growing your app after launch
Launching is the start, not the finish. After release we help you read the analytics, fix friction points, and ship new versions on a steady cadence so the app keeps improving with real usage. We monitor crashes and performance, keep the app compatible with new iOS and Android releases, and prioritise features by what users actually do rather than guesswork. Whether you scale with a fixed-scope engagement or a dedicated team, the goal is the same: a product that grows in value over time while you retain full ownership of the code.
Frequently asked questions
How much does it cost to build a mobile app?
It depends on features, platforms (iOS, Android or both) and complexity. Most teams start with an MVP to control the initial budget, then expand. We survey your requirements and quote per project so the cost matches your actual scope.
How long does it take to develop an app?
A well-scoped MVP typically takes a few weeks to a couple of months; larger apps take longer. We work in short sprints with regular demos so you see progress and can adjust early.
Do you build for both iOS and Android?
Yes. We build native apps for each platform and cross-platform apps that cover both from one codebase. In discovery we recommend the approach that best fits your goals and budget.
Do we own the source code and the app?
Yes. CIT develops to your specification and hands over the complete source code on delivery, so you fully own the app, the data and the roadmap and can upgrade it any time.
How to choose a mobile app development partner
The team you pick matters as much as the idea. Look for a partner who asks about your users and business model before quoting, shows real apps they have shipped, gives you a clickable prototype before writing code, and works in visible iterations rather than disappearing for months. Just as important: confirm you will own the source code, the accounts and the data, so you are never held hostage by a vendor. Clear communication in your language and time-zone overlap keep the project moving. CIT is built around exactly these principles — transparent scope, regular demos, and full ownership handed to you on delivery.
