Mobile app development

Mobile apps with Flutter and React Native, built alongside your web platform

Techtonic Innovations builds cross-platform iOS and Android apps with Flutter and React Native — usually together with the web application and backend they depend on — so one team owns the whole product, the APIs stay consistent, and features ship to web and mobile on the same schedule.

Why cross-platform, and why bundled with web

For most business apps, a single cross-platform codebase is the practical choice: one team, one set of features, and one release process for iOS and Android, instead of two native apps drifting apart. We still write native modules where a feature needs them — a specific hardware integration, a platform SDK, or performance-critical code.

Building mobile and web together matters as much as the framework. When separate vendors build the app, the web front end, and the API, every feature needs three sets of coordination and the API gets shaped around whichever team shouted loudest. We design the backend and API once, for every client, and build the web application and mobile app on top of it, so authentication, data models, and business rules stay consistent everywhere.

Flutter or React Native?

Both are mature, well-supported choices, and we recommend one per project rather than defaulting to either.

React Native

Usually the better fit when your web app is built in React and TypeScript: types, validation, API clients, and business logic can be shared between web and mobile, and your web developers can contribute to the app. We typically build on Expo for faster builds and over-the-air updates.

Flutter

Usually the better fit for highly custom, animation-heavy interfaces that must look identical on every device, or when the team doesn't already have a React codebase to share with. Flutter's rendering engine gives precise control over every pixel.

What we build

Our mobile work covers customer-facing apps, companion apps for SaaS products and e-commerce stores, and internal field and operations tools. Whatever the category, the app is built for real-world conditions: unreliable networks, older devices, and users who expect it to work offline.

  • Customer apps and companion apps for SaaS and e-commerce
  • Internal field-service and operations tools
  • Offline-first data sync and background processing
  • Push notifications, deep links, and in-app messaging
  • Secure authentication, including SSO and biometrics
  • App Store and Google Play submission and release management

AI features in mobile apps

Mobile apps are a natural home for AI features: an assistant grounded in your own content, document and receipt capture that extracts fields from a photo, voice input, smart search, and personalized recommendations. We decide per feature whether the model should run on the device — faster and more private, but limited — or on the server behind your API, where larger models and your data are available. Model calls always go through your backend, never with API keys shipped inside the app. Our AI development services team builds the models and pipelines behind these features.

How a mobile engagement runs

Every engagement starts with a free discovery call, where we learn your goals, systems, and constraints before proposing a scope. We design the API and data model first, then build the app in two-week sprints with test builds on real devices through TestFlight and Google Play internal testing, so stakeholders use the app from early on. We handle store submission, crash reporting, and analytics setup, and hand over the codebase, release process, and documentation — or keep maintaining it if you'd prefer. We work in agile two-week sprints with visible progress every cycle. Many MVPs and first production releases ship in 6 to 12 weeks depending on scope; larger platforms are broken into sprint-sized milestones so you see working software early and often.

Frequently asked questions

If your web app is built with React and TypeScript, React Native usually wins because code and developers can be shared. For highly custom, animation-heavy interfaces or teams without a React codebase, Flutter is often the better fit. We recommend one per project.
