Mobile App Development

The cost of a mobile app depends on its features, the number of platforms, and whether it is native or cross-platform. A focused first version is far cheaper than a full-featured app, and choosing one cross-platform codebase over two native builds can reduce cost significantly.

TechInfini scopes every app with a clear, itemised estimate before work begins.

A straightforward mobile app typically takes two to four months from design to store launch, while larger apps with complex features or integrations take longer. A cross-platform build is usually faster than two separate native apps.

TechInfini provides a phase-by-phase timeline during discovery so you know what to expect.

Native apps — Kotlin for Android, Swift for iOS — give the best performance and access to the latest platform features. Cross-platform frameworks like React Native and Flutter let you ship to both platforms from one codebase at lower cost. The right choice depends on the complexity of your app, your budget and your performance needs, and TechInfini recommends honestly based on your product.

Yes. TechInfini builds for both Android and iOS — either as separate native apps or as a single cross-platform app in React Native or Flutter that runs on both. We help you decide which approach gives the best balance of performance, timeline and budget for your project.

Yes. TechInfini handles the full release process — preparing store listings, screenshots and metadata, configuring developer accounts, and managing submission through Apple App Store and Google Play review to approval. We also support post-launch updates and new releases.

Yes. You own the complete source code, design files and store accounts for your app. Everything is documented and handed over to your team at the end of the project, so there is no vendor lock-in and you are free to maintain or extend the app however you choose.

Yes. TechInfini works on existing apps as well as new ones — fixing crashes and performance issues, redesigning dated interfaces, adding features, and updating apps to support new OS versions. We start with an audit of the current app and recommend the most cost-effective path forward.

React Native uses JavaScript and renders with native UI components, which suits teams already working in the React ecosystem. Flutter uses Dart and draws its own UI, giving very consistent visuals across platforms. Both produce genuine cross-platform apps from one codebase, and TechInfini helps you choose based on your team, design needs and project goals.

Yes. TechInfini offers ongoing maintenance — monitoring crashes and performance, supporting new Android and iOS versions, applying security updates, and building new features. Mobile platforms change constantly, so regular maintenance keeps an app stable, secure and available in the stores.

TechInfini builds security in from the start — encrypted data storage and transmission, secure authentication, safe handling of API keys, and compliance with App Store and Play Store privacy requirements. Security is tested before launch and maintained through updates as platform requirements evolve.
