Mobile Apps That Your Team and Customers Actually Use
Not every business needs a mobile app. But when your team works in the field, your customers want self-service from their phone, or your existing systems need a mobile front door — a well-built app changes how the business operates.
We build custom mobile applications for Australian businesses. Cross-platform apps that run on both iPhone and Android. Native apps when the project demands it. Field tools with offline support. Customer apps with push notifications, payments and booking. Companion apps that extend your existing web platform to mobile.
HELLO PEOPLE is a Perth-based app development company. We use React Native, Flutter, Swift and Kotlin to build apps that integrate with your backend systems, your accounting software, and whatever else your business runs on.
When your team needs mobile access
If your business deals with any of these, a custom mobile app is probably the missing piece.
Field teams working blind
Your crew is on site but the office has no idea what is happening until they drive back and fill in a form. Photos get texted, notes get lost, timesheets arrive days late.
Customers calling for things they should do online
Booking appointments, checking order status, requesting quotes — your team handles these by phone and email instead of letting customers do it themselves from an app.
No connectivity, no work
Your team hits dead zones — mine sites, rural areas, underground floors, basements. The web-based system goes down, data capture stops, and catch-up happens at the end of the day.

Mobile apps we build
The most common types of mobile apps we build for Australian businesses. Pick a tab to see how each one works.
Cross-platform apps (iOS & Android)
One codebase that runs on both iPhone and Android. Built with React Native or Flutter so your app looks and feels native on both platforms without building and maintaining two separate apps.
This is the right approach for most business apps. You get full App Store and Google Play distribution, push notifications, camera and GPS access — at roughly 60–70% of the cost of building two native apps.
We use cross-platform for customer-facing apps, field worker tools, internal operations apps, and SaaS mobile companions.
Native iPhone and iPad apps
Built in Swift for iOS when performance, hardware integration or App Store requirements demand it. Smooth animations, full access to Apple APIs, HealthKit, ARKit, Apple Pay, Siri Shortcuts.
We recommend native iOS when you need deep hardware integration — medical devices, Bluetooth peripherals, augmented reality — or when your entire user base is on Apple.
Published to the App Store with proper review compliance. We handle certificates, provisioning profiles, in-app purchases and TestFlight beta distribution.
Native Android apps
Built in Kotlin for Android when you need tight integration with Google services, specific hardware features, or your users are predominantly on Android devices.
Common in field-heavy industries where rugged Android devices are standard — mining, logistics, trades, warehousing. We build apps that work on the devices your team actually carries.
Published to the Google Play Store. We handle the listing, signing, beta testing and staged rollouts.
Field worker and operations apps
Job tracking, photo documentation, form submission, safety checklists, GPS logging, time capture — all from the field. Data syncs to your backend when connectivity is available.
Built for the reality of field work: bright sunlight (high contrast UI), one-handed operation (large touch targets), unreliable signal (offline support), and dirty hands (simple navigation).
Integrates with simPRO, ServiceM8, Tradify, Deputy and your accounting software so completed work flows straight into invoicing.
Customer-facing mobile apps
Booking apps, loyalty programmes, order-ahead systems, account management, delivery tracking. The kind of app your customers download, use regularly, and associate with your brand.
Push notifications for promotions, appointment reminders, status updates. In-app payments via Apple Pay, Google Pay, or card. Social sharing and referral features if they earn their place.
We design for retention, not downloads. Clean onboarding, fast load times, and features people actually use — not a bloated app that gets uninstalled after a week.
Mobile companion for web platforms
You already have a web app or internal system. The mobile companion gives your team access to the most-used features from their phone — approvals, notifications, quick updates, dashboards.
Not a full rebuild of the web app. A focused mobile tool that covers the 20% of functionality people need when they are away from their desk.
Shares the same backend and APIs as your web platform. Data stays in sync. Users switch between desktop and mobile without missing a beat.
Field app that helped HVAC techs complete 25% more jobs per week
We built a mobile field app for HVAC technicians — job checklists, photo capture, compliance forms, time tracking and automatic Xero invoicing from the field.

Offline access, push notifications, device features, native performance. Here is what mobile app development actually delivers.
Your business in every customer's pocket
A mobile app puts your service, your booking system, your loyalty programme, your communication channel right on the home screen of every customer's phone. No browser, no URL, no searching.
Push notifications bring people back. A well-built app becomes a daily touchpoint — not a website they visit once and forget.
Works where Wi-Fi does not
Field workers on mine sites, delivery drivers between drops, sales reps at client offices — your team does not always have reliable internet. Mobile apps can work offline and sync when connectivity returns.
That means data capture, form submission, photo uploads and job updates keep happening even when the signal drops out.
Camera, GPS, push notifications and more
Mobile apps access hardware features that web apps cannot. Camera for photo documentation. GPS for location tracking. Push notifications for real-time alerts. Biometric login for fast, secure access.
These are not gimmicks — they solve real business problems. Photo evidence on job sites. Driver location for dispatch. Instant alerts when something needs attention.
Performance that users actually notice
Native and cross-platform apps are faster than mobile websites. Smoother animations, instant navigation, no page reloads. Your team and customers get a tool that feels responsive instead of clunky.
For apps that staff use dozens of times a day, that speed difference adds up. Less friction means faster work and fewer complaints.
Integrated with your backend systems
The mobile app talks to your web portal, your accounting software, your CRM, your job management system. Data entered on the phone shows up everywhere it needs to be — instantly.
No duplicate entry. No emailing photos back to the office. No waiting for someone to update the spreadsheet. The app is the front door to your whole operation.
How we price mobile app development
No hourly billing that spirals. No vague estimates. Here is how we approach pricing.
Free 15-minute call
Tell us what the app needs to do. We will give you an honest answer on whether mobile, web, or both is the right approach — and what the realistic next steps look like.
Fixed-price quote
After a free consultation and discovery phase, you get a fixed price for the project. No hourly billing. You know what it costs before development starts.
Staged delivery
We build in phases — each delivering working features to TestFlight and Google Play beta. You see real progress, test on real devices, and pay in milestones tied to what has been delivered.
How the Project Works
Every app is different. The process adapts, but the structure stays the same.
Our field crew used to text photos back to the office and fill in paper forms at the end of the day. Now they capture everything on the app — photos, notes, time, GPS — and it syncs straight to our system. We invoice the same day instead of three days later.

Common questions about mobile app development
Do I need a mobile app or would a web app be enough?
If your users need offline access, push notifications, camera or GPS, or if having an icon on their home screen matters for engagement — a mobile app makes sense. If the tool is mostly used at a desk or only needs a browser, a responsive web app is usually cheaper and simpler. We will tell you honestly which approach fits your situation.
How much does mobile app development cost?
Every project is different, so we do not publish fixed price ranges. We offer a free initial consultation to understand your requirements, followed by a discovery phase. After that, you get a fixed-price quote — no hourly surprises. Book a free 15-minute call and we will give you an honest steer.
How long does it take to build a mobile app?
A focused app — a field tool, booking system, or companion app — typically takes 10 to 16 weeks. Larger apps with complex features, multiple user types and backend integrations may take 16 to 24 weeks, delivered in phases so you see working builds early via TestFlight and Google Play internal testing.
Should I build for iPhone, Android, or both?
For most Australian business apps, both. Cross-platform frameworks like React Native and Flutter let us ship one app to both App Store and Google Play at roughly 60–70 percent of the cost of building two separate native apps. We recommend native only when deep hardware integration or specific platform features require it.
Do you handle App Store and Google Play submission?
Yes. We manage the full submission process — app listings, screenshots, descriptions, review compliance, signing certificates, staged rollouts and beta testing via TestFlight and Google Play internal tracks. We also handle updates and version management after launch.
Can the app connect to our existing business systems?
Yes. We integrate mobile apps with Xero, MYOB, Salesforce, HubSpot, Shopify, simPRO, ServiceM8, Deputy, Stripe and dozens of other platforms via APIs. The app becomes another channel into your existing data — not a separate silo.
Do I own the app and the code?
Yes, 100 percent. Source code, designs, App Store and Google Play accounts, backend infrastructure — all yours. No licensing fees, no lock-in. The accounts are in your name from day one.
What about ongoing maintenance after launch?
iOS and Android release major updates every year, and your app needs to keep pace. We offer monthly support plans covering OS compatibility updates, bug fixes, new features, performance monitoring and App Store compliance. Most clients stay with us because we already know the codebase.
