Starting from $8,000
App Development Company — New Zealand
Every app conversation in New Zealand eventually reaches the same question: Flutter or React Native? Most NZ agencies will steer you toward React Native because that is what their JavaScript developers already know. The honest answer is more nuanced, and it depends on what you are building. We use Flutter as our primary mobile framework, and we have made this choice deliberately. Flutter commands 46% market share among cross-platform developers in 2026 for good reason. Flutter's Impeller rendering engine delivers faster frame rasterization than the previous Skia engine. Pixel-perfect UI consistency across iOS and Android from a single Dart codebase. No JavaScript bridge overhead. 60 to 120 FPS animations without compromise. For most NZ businesses building a product app, a D2C mobile experience, or an internal enterprise tool, Flutter is the right call. You get both iOS and Android from a single codebase, saving 40 to 60% compared to building two native apps. Maintenance is simpler. Updates ship once, not twice. For businesses with an existing Next.js or React web codebase and a need to share significant logic between web and mobile, React Native has legitimate advantages. We build React Native too. We just will not steer you toward it because it is what is familiar. As an AWS Partner, our app backends are deployed on AWS: scalable, monitored, and production-grade from day one. Senior Flutter developers in New Zealand command NZD $80,000 to 140,000 annually. Our fixed-price model delivers equivalent engineering at a 3 to 5 times cost advantage.

Service Overview
Everything you need to know about App Development Company — New Zealand
Most app development proposals from NZ agencies look the same: a React Native estimate, a 20-page scope document, and a timeline that expands from 12 weeks to 32 weeks by the time you reach launch.
We do it differently. Flutter as a primary framework means a single Dart codebase delivers pixel-perfect iOS and Android apps with no JavaScript bridge overhead. Impeller rendering means your app feels native because it is rendering at native speed. A single codebase means maintenance happens once, not twice.

+280% Organic traffic growth (6 months)+45% Average order value increase+33% Repeat purchase rate1.6s Average page load time
Zevarly, a Kolkata-based fashion jewellery brand run by Mukesh Sethiya from the heart of Burrabazar, had built a loyal offline following through wholesale channels. But the brand had zero digital presence — no online store, no product catalogue, and no way to reach the growing wave of women shopping for jewellery online. The challenge was significant: fashion jewellery is one of the most competitive e-commerce categories in India. Customers can't touch or try on products, so every element of the online experience — from product photography presentation to zoom-enabled detail views — needs to build trust and desire simultaneously. Zevarly's product range spans hundreds of SKUs across gold-plated, silver-plated, and American Diamond collections, including bridal sets that need to feel premium even through a screen. Their competitors were already established on Shopify with polished stores, influencer partnerships, and strong Instagram presences. Zevarly needed more than just a website — they needed a complete digital commerce strategy that could compete from day one, with smart navigation for a large catalogue and pricing strategies that encouraged bulk purchases.
Case studyClient stories
What our clients say
Honest words from people who've been through the process. No stock photos, no made-up companies.
“When two freelancers ran away with our money, we had lost all trust in agencies. Innovatrix didn't just rebuild our store — they rebuilt our confidence. Four years later, we've gone from one lakh to over one crore in revenue. They're not our vendor, they're our technology partner.”

Garima Ahuja
Co-founder, FloraSoul India
“We had jewellery but no digital presence. Innovatrix gave us a Shopify store that actually feels like walking into a jewellery showroom. The tiered discounts and WhatsApp integration alone doubled our repeat customers. We went from zero online orders to processing 50+ orders a day within four months.”
M
Mukesh Sethiya
Founder, Zevarly
“Before this system, our team was glued to their phones all day just answering the same questions over and over. Now those hours are back, and our customers actually get faster responses than when we were doing it manually. Rishabh and his team understood our operations deeply before writing a single line of code.”
