App Development Sydney
web apps, iPhone and Android apps, and the support after launch.
App development for Sydney businesses: web apps that open in any browser, mobile apps for staff in the field and customers on the go, built with React for iPhone and Android, and looked after once they are live.
An Australian team with no offshore development, your data in Australian data centres, and one fixed price before work starts.

01 / 04 Web app development
Web apps your customers and staff open in any browser
A Silverwater trade supplier whose customers phone in every order and ask where it is. A Chatswood allied health clinic whose clients email forms back and forth before every first visit. Both need an app, but neither needs one from an app store.
A web app runs in the browser on a phone, tablet or computer, with nothing to install and no store approval to wait for. We build portals, booking systems and internal tools this way, connected to Xero, MYOB and the systems you already use.
- Customer and supplier portals
- Booking and ordering apps
- Staff tools that replace spreadsheets
- Works on any phone or computer
02 / 04 Mobile app development
Mobile apps for the people who are never at a desk
Strata maintenance crews across the Northern Beaches, delivery drivers out of Smithfield, inspectors on building sites with no signal in the basement. They need an app on their phone that keeps working offline and sends everything back to the office when it reconnects.
We build mobile apps for iPhone and Android: job sheets, inspections, photos, signatures and proof of delivery, linked to your office systems. For a regional freight operator, a driver app with digital proof of delivery meant 25 percent more deliveries per driver each day.
- Field service and inspection apps
- Driver and delivery apps
- Works offline, syncs when back in range
- Customer apps on iPhone and Android
03 / 04 React, iPhone and Android
React is the toolkit behind many of the apps you already use. With React for the web and React Native for phones, most of one set of code runs on the web, on iPhone and on Android, so you pay for one build instead of three.
It suits most business apps: portals, booking, field work and customer accounts. Where an app needs something only the phone itself can do well, we write that part for the device and keep the rest shared.
- One codebase for web, iPhone and Android
- React web apps and React Native mobile apps
- Faster updates across every device
- Taking over existing React apps
Some apps live mostly on iPhones and iPads: a clinic's client app, a sales team's catalogue on iPad, an app your customers expect to find in the App Store. These need to feel at home on Apple devices and pass Apple's review.
We build iPhone and iPad apps with Face ID sign in, notifications, the camera and offline use where you need them. We handle the App Store listing and Apple's review, and the developer account stays in your business name.
- iPhone and iPad apps
- Face ID, notifications and camera
- App Store listing and review handled
- Apple developer account in your name
Android runs on most of the rugged phones, handheld scanners and tablets used in warehouses, trucks and on site. A Wetherill Park warehouse picking orders on handheld scanners needs an app built for exactly those devices.
We build Android apps for barcode scanning, picking, deliveries and field work, set up to run on company devices, and we publish customer apps on Google Play. Google asks apps to keep up with new Android versions every year, and we keep yours current.
- Handheld scanners and rugged devices
- Warehouse, delivery and field apps
- Google Play listing and updates
- Company devices set up and managed
04 / 04 App maintenance and support
Your app kept working, through every phone update
Apps do not stay finished. Apple and Google release new versions every year, Google Play asks apps to keep up, and an app nobody looks after starts crashing, or quietly drops out of the store. Often the developer who built it has moved on.
We take over apps built by someone else, get the code and store accounts into your name, and keep the app updated, secure and working. Then we add the features your customers and staff have been asking for.
- Updates for new iPhone and Android versions
- Crash fixes and security updates
- Apps another developer built, taken over
- New features as you need them
How it works
From the first call to the App Store
The same six steps for a web app or a phone app. You know the price before anything is built.
6 steps, from first call to support
-
A 15-minute call
You tell us what the app needs to do and who will use it. We tell you plainly whether it should be a web app, a phone app or both.
-
Scope, and a fixed price
We map the screens and the data with you by video call, or in person in Sydney for larger projects. You get a written scope and one fixed price before anything is built.
-
Tap through it first
You try the main screens as a clickable design on your own phone. Changing a screen now is quick. Changing a built app is not.
-
Test it on your phone
Every two weeks you get a new test version to install on your own phone, using your real data, so you can steer the app as it takes shape.
-
Into the stores and live
We publish to the App Store and Google Play under your business name, set the web version live and train your team.
-
Kept up to date
Updates for new iPhone and Android versions, fixes and new features, from the same people who built it.
Meet the person
Your app, built by the person you talk to
The founder scopes every Sydney app project and builds it, through to the day it goes into the stores.
HELLO PEOPLE designs, builds and looks after AI, software, app and data solutions for Australian businesses, with senior expertise on every project and a scope agreed before work starts. For software, that means starting with how your business runs, not with the code.
Since 2007, HELLO PEOPLE has delivered more than 100 projects from Perth for small and medium businesses across Australia: custom software and apps, system integrations, data migrations, reporting and dashboards, and AI that works inside the systems a business already runs.
I lead every engagement myself. I trained in accounting before moving into IT, hold accounting and IT professional qualifications and an MBA, and bring more than 20 years of experience across sales, service delivery, inventory and compliance. I am also a PhD candidate in AI at Curtin University, researching retrieval-augmented generation (RAG), so the technology is always judged by what it does for the business.
-
An old-fashioned service
Small and boutique. The person who scopes your software is the person who builds it, and the same person is there on launch day.
-
Quick responses
No ticket queue and no account manager in between. You hear back within one business day, usually sooner.
-
A long-term partner
The first release is the start, not the end. When you need the next system, integration or report, you call the same person, who already knows your business.
Why Sydney businesses build their apps with us
-
Australian team, no offshore development
Your app is designed and built in Australia by the people you speak to. Nothing is handed to an offshore team.
-
Your data in Australian data centres
The app's database and files are hosted in Australian data centres unless you ask otherwise.
-
One fixed price, agreed first
You know the full cost before work starts. No hourly billing and no surprise invoices.
-
The app and the store accounts are yours
Source code, designs, data and the App Store and Google Play accounts are in your business name.
-
Sydney hours covered
Perth is two hours behind Sydney, three during daylight saving, so we overlap most of your working day. We fly over for kickoff workshops and key milestones.
Questions Sydney businesses ask before building an app
Which app development company in Sydney can build an app for a small business?
HELLO PEOPLE builds web apps, iPhone apps and Android apps for small and medium businesses in Sydney, from customer portals and booking apps to field service and delivery apps. It is an Australian team with no offshore development, quotes one fixed price before work starts, and hands over the code and store accounts in the client's name.
Should we build a web app, an iPhone app, an Android app, or all three?
If people use the app at a desk or only now and then, a web app is usually enough and is quickest to build. If they use it all day in the field, need it offline or need the camera and scanner, a phone app is better. HELLO PEOPLE often builds both from one set of React code, so the choice does not mean paying three times.
What is React Native, and is it good enough for a business app?
React Native lets most of one set of code run as a real app on both iPhone and Android, instead of building two separate apps. It is used by many large companies and suits most business apps. HELLO PEOPLE uses it for most mobile work and writes device-specific parts only where an app needs them.
How much does it cost to build an app in Sydney?
It depends on the number of screens, the types of user, whether it runs on the web, iPhone, Android or all three, and which systems it connects to, so a general figure would mislead. HELLO PEOPLE starts with a free 15-minute call, scopes the app and gives one fixed price for the build. There is no hourly billing.
How long does it take to build an app?
A focused app such as a booking app or a field app usually takes 8 to 12 weeks, including App Store and Google Play review. Larger apps with several types of user and connections to other systems take 16 to 24 weeks, released in stages so people can start using it earlier.
Can you take over and update an app another developer built?
Yes. HELLO PEOPLE takes over apps whose original developer has moved on. It first gets the code, hosting and App Store and Google Play accounts into your name, then fixes crashes, updates the app for new iPhone and Android versions and adds new features.
Who owns the app and the App Store listing?
You do. HELLO PEOPLE publishes the app under your own Apple and Google developer accounts and hands over the source code, designs and data. There are no licence fees, and you can move to another developer at any time.
Where is our app's data stored?
In Australian data centres, unless you ask for something else. HELLO PEOPLE is an Australian team with no offshore development, so your app and its data stay with people and systems in Australia.
Does HELLO PEOPLE have an office in Sydney?
Not yet. HELLO PEOPLE is based at Level 16, 240 St Georges Terrace, Perth, and works with Sydney businesses by video call and phone, with visits to Sydney for workshops and milestones. You can call 0425 531 127 during Sydney business hours.
