Software Development
Mobile App Development for apps your customers keep on the home screen.
iOS and Android apps your customers keep on the home screen, and your team relies on in the field. Avaib designs, builds, ships and supports custom mobile apps end to end: native where it counts, cross-platform where it saves, and owned entirely by you.
Delivered for teams in Australia, the United States, Canada and the Middle East.
What it is
Software that lives in your customer's pocket.
Mobile app development is the craft 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 reaches from the screens a user taps through, down to the back-end services, databases and APIs that quietly power everything behind them. For over 20 years, Avaib has built iOS and Android apps end to end for businesses worldwide.
A mobile app does what a browser-based web app can't. It sits on the home screen, sends the push notification that brings a customer back, works with the camera, GPS and sensors, and keeps working when there's no signal. Done well, it's the most direct line you have to a customer or the sharpest tool you can hand a team in the field. Done badly, it's slow, crashes on the phone someone's actually holding, drains the battery, and collects one-star reviews, which is exactly where lower-cost builds tend to fall apart.
Whether you need a consumer app, a field-workforce tool, an internal enterprise app or a rescue of one an old agency abandoned, we deliver mobile app development services that are fast, secure and cost-effective, native in Swift and Kotlin or cross-platform in Flutter and React Native, senior-built, backed by a real QA department, and owned outright by you, right down to your own store accounts β for clients across a wide range of industries.
Got an app idea, or an app that's stopped working? That's exactly what we build and rescue.

Shipping to the app stores since the smartphone era began.
Avaib is a custom software development company that has spent two decades turning the way a business runs into software people actually use, including the apps in their pockets. We take the manual, paper-and-spreadsheet parts of your operation and rebuild them as clean mobile apps your customers and crews reach from anywhere.
We've shipped apps that grew from a founder's first version to national scale, and in one case through to an enterprise acquisition, alongside field-workforce apps, consumer apps and reporting tools for clients across the US, Canada, Australia and the Middle East. What sets our mobile app development apart is the combination most studios can't offer at once: senior native and cross-platform specialists, a dedicated QA department testing on real devices, genuinely cost-effective rates, and client relationships measured in years.
We work as a single, full-cycle partner across discovery, UX, prototyping, development, testing, store submission and long-term support, all under one roof, so you have one accountable team for the whole life of your app, and it's published under your accounts, not ours.
Two decades of shipping apps that stick.
Want a partner who's still around when the next iOS update lands? That's how we work.

Mobile app development, whatever the shape.
From a single-purpose field tool to a consumer marketplace that scales to national downloads.
Native iOS & Android apps
Fully native apps built in Swift and Kotlin for the moments raw performance, camera, sensors or offline power really matter, polished to feel right at home on each platform.
Cross-platform apps
One codebase in Flutter or React Native that ships to both iOS and Android, giving you the same quality for close to half the build and maintenance cost of two native apps.
Consumer & marketplace apps
Customer-facing apps with accounts, payments, ratings, chat and push notifications, built to survive App Store review and scale to national download numbers.
Field & workforce apps
Apps for teams on the move: job dispatch, inspections, delivery, proof-of-completion and offline data capture that syncs the moment signal returns.
Enterprise & internal apps
Secure internal apps that plug into your ERP, CRM and back office, distributed to staff devices with the access control and compliance a large org needs.
App modernisation & rescue
Inherited a broken or abandoned app? We take over the codebase, fix what's failing, get it back through store review and bring it up to current OS versions.
Don't see your exact use case? We've almost certainly built something like it.
Get a free quoteWhy build an app
The case for a custom mobile app.
Six reasons businesses put their software on the phone, and stay glad they did.
Reaches customers where they already are
People live on their phones. A well-built mobile app puts your brand on the home screen, sends the push notification that brings them back, and works with the camera, GPS and offline storage a browser tab simply can't reach.
One codebase, not two bills
Where it fits, we build cross-platform in Flutter or React Native so a single team ships to both iOS and Android, cutting build and ongoing maintenance cost close to half versus funding two separate native teams.
Fast, smooth and battery-friendly
A janky, battery-draining app gets deleted and one-star-reviewed. We profile performance, animation smoothness and battery use on real devices, so the app stays quick and light the way users expect.
Survives store review and OS updates
We know Apple's and Google's guidelines and build to them, so your app clears review instead of bouncing for weeks, and we keep it working when the next iOS or Android version lands.
Secure on the device and the wire
Secure storage, encrypted traffic, proper authentication and protection of user data are built in from the start, important for consumer trust and essential in regulated sectors.
You own the app and the store accounts
The source code is yours, and the app is published under your own Apple and Google developer accounts, so you're never locked out of your own product or held hostage by a vendor.
Not sure you even need an app rather than a mobile website? We'll give you an honest answer.

What sets Avaib apart from other app development companies.
Most mobile app development companies can offer one or two of these. Our whole model is built to give you all of them at once.
20+ years, since 2004
Not a fly-by-night studio that ghosts you after submission. Two decades of shipping apps and client relationships measured in years.
Senior specialists only
Your app is built by senior mobile engineers who ship to the stores every week, never juniors quietly learning on your budget behind a "senior rate" quote.
A real QA department
Every release is tested on a rack of real iPhones and Android phones, manual and automated, so it doesn't crash on the exact device your customer is holding.
You own the app AND the accounts
Source code is yours, and the app ships under your own Apple and Google developer accounts. No lock-in, no being shut out of your own product.
Senior expertise, without the premium price tag
Enterprise-grade mobile engineering from around USD 25/hour: the quality Australian, US, Canadian and Middle-East agencies charge a fortune for, at a fraction of the price.
AI-accelerated delivery
Our senior mobile engineers use AI coding tools professionally to move faster through the routine work, while a human owns the architecture and reviews every release. Your app ships sooner, at the same quality bar.
One accountable team
No coordinator wall. You talk to the engineers actually building your app, and they aren't splitting their week across a dozen other accounts.
We don't vanish at launch
30-day post-launch warranty and ongoing update support as iOS and Android change, which is why 80%+ of our clients stay with us for years.
600+ projects, proven

The complaints people have about app agencies, and what we do instead.
These are the frustrations we hear most often from teams who've been burned before. Here's exactly how Avaib is set up to avoid each one.
"Our app got rejected by the App Store four times β the developer had no idea what the guidelines even were."
We build to Apple's and Google's review guidelines from the start and handle submission ourselves, so your app clears review instead of bouncing for weeks. Getting it live is our job, not your headache.
"The app was slow and drained the battery β the reviews and the uninstalls followed."
We profile performance, smoothness and battery use on real devices throughout the build, because a laggy, power-hungry app gets deleted. Fast and light is part of the brief, not a hope.
"An iOS update landed and our app just stopped working β the agency was long gone."
Every build ships with a 30-day warranty and ongoing update support as the OSes change. It's why 80%+ of our clients stay for years, several for more than nine.
"They quoted senior developers and delivered juniors β the code was a mess."
Avaib staffs senior mobile specialists only, and the engineers who scope your project are the ones who build it. No bait-and-switch, no learning on your budget.
"Turns out the app was published under THEIR developer account β we're locked out of our own app."
Your app is published under your own Apple and Google developer accounts and the source code is yours outright. You can never be shut out of your own product or held to ransom.
"We paid to build it twice β a separate iOS team and a separate Android team, double the bill."
Where it fits, we build one cross-platform codebase in Flutter or React Native that ships to both stores, roughly half the build and maintenance cost of funding two native teams.
"Timezone gaps turned a simple update into a two-week saga."
Our teams run around the clock, so work moves while you sleep and urgent requests are typically picked up within the hour.

Apps with results you can measure.
A few of the 600+ projects we've delivered across industries and continents.
From startup app to national contractor marketplace
We partnered with a field-service booking business from its earliest startup days, building the apps and platform that carried it through to a national marketplace and on to a successful enterprise acquisition. One of several startups we've helped grow into small and medium enterprises.
One app for crews on the move
We delivered a cross-platform field app for a services operation, with job dispatch, on-site data capture and proof-of-completion that works offline and syncs the moment signal returns, all from a single codebase across iOS and Android.
A consumer app built to survive store review and scale
We built and shipped a customer-facing app with accounts, payments and push notifications, taking it cleanly through Apple and Google review and standing it up to handle real download traffic without falling over.
75% lower development cost for a media client
By moving a Canadian media and broadcasting client onto a leaner, AI-accelerated development cycle across their web and mobile reporting tools, we cut their development investment by around 75% versus local vendor quotes, with the same quality and a 30-day warranty.

Mobile app development, answered.
What is 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.
Should we build a native or a cross-platform app?
It depends on your goals and budget. Native apps, Swift for iOS and 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.
How much does it cost to develop a mobile app?
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.
Will you handle getting the app into the App Store and Play Store?
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, from metadata and screenshots to 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.
What happens when a new iOS or Android version comes out?
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.
Do I own the app and its source code?
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.
How do you make sure the app works on all those different phones?
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.
Can the app connect to our existing systems?
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.
Is the app secure and does it protect user data?
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.
How long does it take to build a mobile app?
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.
What industries do you build mobile apps for?
We deliver mobile apps across manufacturing, healthcare, logistics, construction, education, professional services and retail: plant-floor and inventory apps in manufacturing, 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.
Will you maintain and update the app after launch?
Yes. Every launch comes with a 30-day post-launch warranty, and we offer ongoing maintenance covering 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.
