Mobile App Development

Mobile app development is the process of designing, building, testing and publishing software that runs on smartphones and tablets — the apps people install from the Apple App Store and Google Play. It spans everything from the on-screen experience users tap through, to the back-end services, databases and APIs that power it behind the scenes.

A good mobile app does what a website in a browser can't: it lives on the home screen, sends push notifications, works with the camera, GPS and sensors, and keeps working offline. For over 20 years Avaib has built iOS and Android apps end to end for businesses worldwide.

It depends on your goals and budget. Native apps — Swift for iOS, Kotlin for Android — give you the last drop of performance and the tightest access to device features, but you effectively build and maintain the app twice. Cross-platform frameworks like Flutter and React Native let one team ship to both stores from a single codebase, cutting cost and time close to half.

For most business apps, cross-platform is the smart, cost-effective choice; for performance-critical or hardware-heavy apps, native can be worth it. We'll give you an honest recommendation for your specific case as part of a free estimate — not a one-size-fits-all pitch.

Cost depends on scope and complexity — a focused single-purpose app costs far less than a marketplace with payments, chat and real-time features. Avaib's model is senior engineering at a cost-effective rate (typically around USD 25/hour for development), and choosing one cross-platform codebase over two native ones cuts the bill further.

That's why clients in Australia, the US, Canada and the Middle East come to us to build the same quality for a fraction of local agency prices. Send your requirements and you'll get a free, no-obligation estimate with a clear scope and a ballpark price — usually within one business day.

Yes. We know Apple's and Google's review guidelines and build to them from the start, then handle the whole submission process for you — metadata, screenshots, privacy details and the review back-and-forth — so your app clears review instead of bouncing for weeks.

Crucially, we publish under your own Apple and Google developer accounts, so you own the store listings and are never locked out of your own product.

New OS versions can quietly break an app that isn't maintained — which is exactly how so many apps end up abandoned and failing. We build with that in mind and offer ongoing maintenance that keeps your app compatible, secure and using new platform features as Apple and Google evolve.

Every launch also comes with a 30-day post-launch warranty, and our teams run around the clock, so urgent breakages are picked up quickly rather than sitting for weeks.

Yes, completely. The full source code is yours, and the app is published under your own Apple and Google developer accounts — a detail that trips up many businesses who later discover their old agency controls the account and won't let go.

You're free to host the back end where you like, extend the app with any team you choose, and take the roadmap wherever the business needs. No per-seat licence, no lock-in.

We test on real hardware, not just simulators. Our dedicated QA department runs every release across a rack of real iPhones and Android devices spanning different screen sizes, OS versions and price points — because a phone that lags on a mid-range Android is still a lost customer.

We combine that manual testing with automated tests, so quality holds up release after release rather than slipping as the app grows.

Yes — most business apps have to talk to something you already run. We integrate your app with your CRM, ERP, accounting, payment gateways and third-party APIs through clean, secure services, so data flows in one loop instead of being re-keyed between systems.

Where you have older or legacy back-office software, we can wrap it in a modern API so your shiny new app has something solid and secure to talk to.

Security is built in from the first line. We use secure on-device storage, encrypt data in transit, implement proper authentication and follow platform security best practices — important for consumer trust and essential in regulated sectors like healthcare and finance.

For projects that need it, we add the audit logging, encryption and compliance controls your industry and the app stores' privacy rules require.

A focused MVP can ship in a few weeks; a fuller consumer or business app takes a few months; a complex marketplace with payments, chat and real-time features runs longer.

We work in short, agile sprints, so you see and tap working builds early and often rather than waiting months for a big reveal, and we agree a clear timeline with milestones during the UX-and-prototype stage.

We deliver mobile apps across manufacturing, healthcare, logistics, construction, education, professional services and retail — from plant-floor and inventory apps in manufacturing, to patient and clinician apps in healthcare, driver and delivery apps in logistics, on-site job and inspection apps in construction, learning apps in education, and loyalty and shopping apps in retail.

Two decades and 600+ projects mean we usually bring real domain knowledge to the table, not just code — so we understand your sector's workflows and compliance needs from day one.

Yes. Every launch comes with a 30-day post-launch warranty, and we offer ongoing maintenance — OS-compatibility updates, new features, monitoring and store-listing upkeep — so your app doesn't quietly rot into the abandoned pile.

Our teams run around the clock across time zones, so urgent issues are picked up quickly — typically within the hour — and you have one dependable partner for the life of the app rather than a build-and-vanish vendor.
