Making RFID work in the real world: Lessons from Rotaforms’ bin rollout
Ledger recorded 26,434 bins as delivered while Rotaforms adapted the field workflow, crews and devices around a live rollout.
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.
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

Fast startup, smooth animations and optimized network usage that keeps users engaged—not waiting.
Leverage native, cross-platform or PWA approaches based on ROI, timeline and feature needs.
Authentication, encryption, secure storage and hardened APIs ensure data integrity and user trust.
Task-focused interfaces with clear hierarchy, offline resilience and fast input patterns that reduce training time and operational friction.
Push notifications, location, camera, sensors, bluetooth, payments—integrated with backend & third-party services.
Release pipelines, crash reporting, A/B testing and usage telemetry built into your delivery process.
We select the right stack for your needs—balancing performance, speed to market and long-term maintainability.

Upgrading an existing RFID management system to be able to become cloud native and able to integrate with an existing ordering application.

The calculations for weight loading allowances are complicated, and mixing truck and trailer lengths adds complexity. We built FiveASH a tool to allow drivers to quickly and accurately calculate safe and legal loads, giving them reassurance they are meeting safety and compliance guidelines.

Pixpix is available on the Android and iOS app stores. Download the app, connect your Instagram and Photos Library and you’re all set to order high quality prints - delivered direct to your door.

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.

Surf Life Saving Northern Region is modernising and taking its place as one of New Zealand’s leading emergency services. Improving on-beach data collection was a critical stage in this journey and Calo has developed a digital solution allowing for real time data collection while digitising outdated and inefficient paper processes.
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.
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.
Yes, we manage provisioning, store listings, review compliance and staged rollout strategies.
We offer release management, monitoring, crash triage, feature iteration and growth optimization services.
