iOS & Android Apps — One Build, Two Platforms

We build cross-platform mobile apps using React Native so your app runs natively on both iPhone and Android without paying to build it twice. One codebase, full native performance, half the cost.

Whether you need a customer-facing app, a field tool for your trades team, or an internal operations app, we design and build it to feel right on every device.

One build. iOS App Store & Google Play. Ready to download.

Powerful Web Apps That Run in Any Browser

Not every business needs a native mobile app. A well-built web application gives your customers and team a powerful, app-like experience without the App Store — accessible from any device, instantly.

We build custom web apps for booking systems, client portals, dashboards, job management platforms, and more. If your business has a workflow, we can build a tool around it.

No download required. Works on every device. Easy to update.

03 Progressive Web Apps (PWA)

The Best of Both — App Feel Without the App Store

Progressive Web Apps are web applications that behave like native mobile apps. Users can add them to their home screen, receive push notifications, and use them offline — with no App Store involved.

PWAs are a cost-effective option for businesses that want an app-like experience without the overhead of separate iOS and Android codebases or App Store review processes.

Install from a browser. Works offline. Feels like a native app.

We Handle the Launch So You Don't Have To

Getting an app onto the App Store and Google Play is a process with a lot of steps — developer accounts, certificates, screenshots, metadata, review compliance, and more. We take care of all of it.

From setting up your developer accounts to managing the review process and handling any rejections, we manage your app launch end-to-end so the release goes smoothly.

You focus on the business. We'll get the app live.

How We Work

From Idea to App Store

A clear, milestone-based process so you're never in the dark about where your app is at.

01

Discovery

Free call, ~60 mins

We understand your users, your goals, and the core problem your app solves. No jargon — just a straight conversation.

02

Design & Prototype

1–2 weeks

We design the app screens and user flows in Figma. You see exactly what you're getting before a single line of code is written.

03

Build & Test

Milestone-based

Development in clear stages with regular builds for you to test on your actual device. No big-bang surprise at the end.

04

Launch & Support

Ongoing

We submit to the App Store and Play Store, handle any review feedback, and offer ongoing maintenance after launch.

App Pricing That Reflects What You Actually Need

A simple app with five screens and a simple booking form is a very different job to a multi-role platform with real-time data. We scope every project individually so you get a price that's honest for the work involved.

As a guide, most mobile apps start from around $15,000 and web apps from around $8,000 — but we'll give you a proper estimate after understanding what you're building.

What Our Clients Say

We needed a field app for our trades team to log jobs and photos on site. KY Web built exactly that — works on iOS and Android, the guys love it, and it saved hours of back-and-forth every week.

Aaron B.
Director • NZ trades & services business

The booking app they built replaced a clunky manual process we'd been using for years. Our clients book on their phone in under a minute. Revenue is up and admin time is down.

Priya M.
Owner • NZ wellness & appointments business

We weren't sure whether we needed a native app or a web app. KY Web talked us through it properly and recommended a PWA — it was the right call and saved us about $20k versus building native twice.

Common Questions

What's the difference between a mobile app and a web app? +
A mobile app is downloaded from the App Store or Google Play and installed on a phone. A web app runs in a browser on any device — no download needed. Both can look and feel like an app. We'll help you choose the right approach based on your users and use case.
How much does an app cost? +
It depends on what you're building. Simple booking or field apps typically start from around $15,000 for mobile or $8,000 for a web app. More complex platforms with multiple user roles, integrations, or real-time features will be higher. We'll give you a proper estimate after a free scoping call.
Do I need separate apps for iPhone and Android? +
Not with us. We build cross-platform apps using React Native — one codebase that runs natively on both iOS and Android. This typically halves the development cost versus building two separate apps.
How long does it take to build an app? +
Simple apps with limited screens and features can be delivered in 6–10 weeks. More complex apps with multiple user types, integrations, and advanced features typically take 12–20 weeks. We'll give you a timeline estimate after scoping your project.
Do you handle App Store submission? +
Yes, always. App Store (Apple) and Google Play submission is included in every mobile app project. We handle developer account setup, screenshots, metadata, review compliance, and managing any rejection feedback.
Who owns the app after it's built? +
You do — completely. All source code, design assets, credentials, and intellectual property are handed over at the end of the project. No lock-in, no ongoing licensing, no strings attached.
What's the 30-day money-back guarantee? +
If you're not satisfied with the work within the first 30 days of the project starting, we'll refund you. We stand behind the quality of what we build and we've never had to honour it yet.
