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.

Calo unlocks RFID functionality for Beca project at NZ Steel
Calo partnered with Beca and ZenTag to implement an RFID (Radio-Frequency Identification) system for NZ Steel's Electric Arc Furnace (EAF) project. This $300 million project requires efficient management of a large number of parts. Calo developed an app that connects ZenTag's RFID hardware to Beca's existing project management system, allowing for accurate tracking and easy location of parts as they are offloaded from shipping containers. The system enables real-time inventory updates and faster part fulfilment, improving overall efficiency and reducing errors for the Beca team.

View Project Frequently Asked Questions
Native vs Cross-Platform—What should I choose?
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?
MVPs can launch in 8–12 weeks. Full-featured production builds typically take 3–6+ months depending on complexity, integrations and iteration cycles.
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.
