We build cross-platform and native mobile applications that deliver outstanding user experiences. Our mobile team understands the nuances of app store optimisation, offline-first architecture, and en…
A complete, opinionated stack of capabilities — from architecture to launch — without the agency overhead.
Building an app is the easy part — building one people open every day is the hard part. At Tech Bintang LLC, our Austin-based team of 50+ has shipped mobile products across iOS and Android for clients in the US, UK, and Australia, and we focus relentlessly on the things that decide whether an app succeeds: speed, reliability, intuitive UX, and a clear reason to come back.
Whether you are validating a new idea with an MVP or scaling an established product, we build cross-platform apps with React Native and Flutter for speed to market, and drop to native Swift or Kotlin when performance demands it.
React Native and Flutter let us ship to both iOS and Android from one codebase — faster delivery, lower cost, and consistent behaviour. When a feature needs raw device performance, we write native modules in Swift or Kotlin so you never have to choose between speed of delivery and speed of the app.
Real-world networks are unreliable. We design data layers that work offline and sync intelligently when connectivity returns, so your app stays usable on a train, a plane, or a patchy mobile signal.
Push notifications, deep linking, and thoughtful onboarding are designed from the start to drive activation and retention — not bolted on later. We instrument the app with analytics and crash reporting (Amplitude, Sentry) so you can see what users do and fix issues before they spread.
We manage submission end to end: store listings, screenshots, metadata, App Store Optimisation, and the review process for both Apple and Google. Phased rollouts let us release safely and roll back instantly if anything looks off.
We start with UX research and a validated prototype before writing production code, then build feature-by-feature in two-week sprints with TestFlight and Play Beta builds so you review real progress continuously. Most MVPs reach the stores in eight to sixteen weeks depending on scope.
One of the first decisions in any mobile project is the technology approach, and getting it right saves both money and months. Cross-platform frameworks like React Native and Flutter let us maintain a single codebase that runs on both iOS and Android — ideal for most products, especially MVPs and apps where time-to-market and budget matter. Native development in Swift (iOS) or Kotlin (Android) shines when an app leans heavily on device hardware, demanding graphics, or platform-specific features. In practice we often build a cross-platform core and write small native modules for the few places that truly need them, giving you the economics of one codebase with the performance of native where it counts.
Getting installs is a marketing problem; keeping users is a product problem. We design onboarding that gets people to their first moment of value quickly, use push notifications and deep links thoughtfully (never spammy), and instrument the app so you can see exactly where users drop off. That data turns guesswork into a prioritised roadmap of improvements that actually move retention and engagement.
Most apps are only as good as the backend behind them. We build secure, scalable APIs and integrate the services your product needs — authentication, payments, real-time messaging, analytics, and third-party platforms. With an offline-first data layer, your app stays responsive even on poor connections and syncs cleanly when the network returns.
We work with founders validating a new idea, funded startups scaling a live product, and established businesses bringing a service to mobile for the first time, across the US, UK, and Australia. As a US-registered company in Austin with a 50+ person team, we can take a product from first wireframe through store launch and ongoing iteration without you having to assemble and manage a team of your own.
Mobile users are unforgiving — one crash or a clunky flow and they uninstall. We treat quality as part of the build, not an afterthought: automated and manual testing across real devices and OS versions, performance profiling to keep the app smooth and battery-friendly, and security practices that protect user data and meet App Store and Google Play requirements. Crash reporting and analytics are wired in from day one so issues surface immediately and get fixed before they spread.
App costs vary widely because scope varies widely. A focused MVP with a handful of core screens is a very different project from a feature-rich app with a custom backend, real-time features, and deep integrations. Rather than quote a vague range, we scope your specific requirements on a free discovery call and return a fixed-price proposal with a clear timeline and milestones. Most MVPs land between eight and sixteen weeks; larger builds are phased so you can launch core value early and expand from there.
Apps need care after launch — OS updates, new devices, store policy changes, and the next set of features your users ask for. We offer maintenance and growth retainers so your app stays current, stable, and improving, with analytics-driven decisions about what to build next.
A fast, stable app your users keep coming back to — with analytics to prove it, a clean path through app-store review, and a team that stays with you after launch to optimise retention and ship the next set of features. Pricing starts from $8,000 and we provide a fixed-price proposal after a free discovery call.
Refined over 200+ projects. Predictable timelines, clear milestones, no surprises.
User interviews and competitive analysis to define navigation and interaction patterns.
High-fidelity Figma prototypes tested with real users before development.
Feature-by-feature delivery with TestFlight/Play Beta for continuous stakeholder review.
ASO strategy, screenshots, metadata, and ratings framework built in from day one.
Phased rollout strategy, analytics dashboard, and retention mechanics setup.
Three reasons enterprises trust us with mission-critical projects.
Security reviews, automated testing, and code review on every PR. Security-focused practices baked in from day one.
Most projects ship 30-50% faster than competitor benchmarks — because our seniors don't need hand-holding.
98% client retention. We're still maintaining systems we built in 2014 — and that's the way we like it.
Straight answers to the questions we hear most about mobile app development.
Mobile projects start from \$8,000. A focused MVP costs less than a feature-rich app with custom backend, integrations, and native modules. We scope your requirements on a free call and send a fixed-price proposal.
For most products, cross-platform (React Native or Flutter) is the smart choice — one codebase ships to both iOS and Android, lowering cost and time. When a feature needs maximum performance, we add native Swift/Kotlin modules. We will recommend the right mix for your goals.
Yes. We manage the full submission process for both stores — listings, screenshots, metadata, App Store Optimisation, and the review process — and use phased rollouts so launches are safe.
Most MVPs reach the stores in eight to sixteen weeks depending on scope. We work in two-week sprints with beta builds so you see progress throughout and can adjust priorities.
Yes. We instrument every app with analytics and crash reporting so you can track installs, active users, retention, and stability, and we use that data to guide improvements after launch.
