Mobile app development in NZ

Give field staff the records and tasks they need on a phone or tablet. We build business apps for iOS and Android, connected to your existing systems.

Mobile App Interface Illustration

We work through where staff use the app, which device features they need, and what must happen when a connection drops. Those decisions shape the interface, offline behaviour and links to your other systems.

That might be patrol coordination, a field service app or reporting across several sites. We agree what the first release needs to do and how your team will test it in daily work.

Real-World Impact

Surf Life Saving New Zealand operates a Calo‑engineered mobile platform across 90+ patrol locations every summer.

Staying safe and operational during COVID-19

In March 2020 New Zealand went into the first COVID-19 lockdown and organisations needed to establish systems to operate safely. The greatest COVID-19 management tool available at the time was social distancing and contact tracing - both new concepts for the business safety landscape in New Zealand. Downer NZ took proactive action and approached OnSight* to build an app to support safe operations and help essential employees maintain social distancing.

Frequently Asked Questions

Should we choose native or cross-platform development?

It depends on performance requirements, device feature usage, budget and roadmap. We help you evaluate trade-offs and often start with cross-platform to validate, moving native where deeper optimization is needed.

How long does a mobile app take to build?

The timeline depends on the first release, the systems it needs to connect to and how much testing is needed on staff devices. We agree the scope and delivery plan with you before development.

Do you handle App Store & Play Store submission?

Yes, we manage provisioning, store listings, review compliance and staged rollout strategies.

Can you support ongoing releases?

We offer release management, monitoring, crash triage, feature iteration and growth optimization services.
