Mobile app to help

stolen vehicle 

recovery

As the UK's leading stolen vehicle recovery specialist with over 30 years of experience, Tracker offers an account-based service that lets members track their vehicles, record trips, perform security checks, and report thefts. Most customers access these features through a mobile app. But, with the market becoming increasingly competitive, Tracker needed to maintain its leading position by improving the app's user experience and introducing innovative new features.

The Problem

Tracker partnered with Si digital to enhance their Tracker Touch mobile app. We developed the app in React Native to ensure compatibility with both Android and iOS. Using TypeScript, we efficiently integrated data from Tracker's backend REST APIs.The mapping features include vehicle geofencing, crime hotspot visualisation, and movement tracking, all implemented using native Apple and Android maps.For emergency situations, we integrated direct in-app calling to Tracker's support team.

The Solution

The resulting app is clean and easy to navigate, giving drivers peace of mind with vehicle security at their fingertips. Tracker calls the Touch app "the new secret weapon in vehicle tracking technology"—and we couldn't agree more. The app has already reached over 5,000 downloads on the Google Play store alone.We continue to work with Tracker on new features and developments. You can find out more about the Touch app on Tracker's website.

Setting the foundation for a future-proofed digital presence for Harwin.

Harwin came to us wanting to refresh their online presence, modernise their platform, and fix the technical issues that had built up over time. More importantly, they needed a website that could actually handle 4,000+ products and make them easy to find.So, we rebuilt the site from the ground up. The new platform brings together Harwin’s <a href="https://sidigital.co/services/integrate/salesforce">Salesforce</a> system for product data, <a href="https://sidigital.co/services/integrate/asset-management-software">Bynder</a> for digital assets, and Payload CMS for content management, all via our secure <a href="https://sidigital.co/faraday">Faraday middleware</a>. Everything syncs automatically, so when Harwin updates a product in Salesforce, it appears on the website almost instantly.The results speak for themselves. Pages load 90% faster, product information stays accurate across over 4,000 products, and customers can find exactly what they need without the wait. It's a website that matches the precision of Harwin's aerospace-grade connectors.

Harwin manufactures over 4,000 products. From connectors for spacecraft and medical devices to high-reliability applications like UAVs. We redesigned and restructured how customers discover and explore them.

Always up-to-date Thanks to our <a href="https://sidigital.co/faraday">bespoke middleware, Faraday</a>, the Harwin website syncs website data with their Salesforce database. When their team updates a product, those changes appear almost instantly. No manual updates, no stale data. Salesforce also acts as a source of truth for all of Harwin’s data, so there’s one key place to check data.Filtering that works We integrated Elastic Search to handle complex queries instantly. Filter by connector type, mounting style, contact material, or any combination, and results appear in milliseconds. We’ve seen a 97% increase in filter interaction since launch, showing customers are actually using it.Everything in one place Product images and technical documents pull from Bynder. CAD files display through TraceParts and Samacsys. Real-time stock availability appears via TrustedParts. All running on our custom middleware and a REST API.

Finding Products, Fast

Harwin’s new website is built using Payload, a modern, headless CMS.

The site is built using Payload CMS, a modern content management system. Harwin's marketing team can create and edit pages without developer help. Dynamic components keep the design consistent while giving them flexibility for new content.The interface is clean, navigation is logical, and everything is built to help users find what they need fast. Want to know more about why we use Payload? Read our <a href="https://sidigital.co/lab-notes/why-weve-swapped-wordpress-for-payload">Lab Note about the benefits</a>.

Built on Payload

We built a tool that lets Harwin's customers configure custom cables, preview them in 3D, and submit them directly to sales.

Many of Harwin's customers need cables built to exact specifications. We designed and built a tool that lets them configure exactly what they need, see it in 3D, and submit it directly to Harwin's sales team.The interface uses a sidebar layout that guides users through each option logically, taking them through cable length, connector type, contact configuration, and more. As they build, a live 3D model updates in real-time via CADENAS' rendering engine. Visual cues like colour selectors and clear selection states make the process straightforward, even for more complex configurations.Once configured, users can submit their request, which feeds directly into Harwin's Salesforce. They can also download a PDF datasheet or export CAD files in multiple formats. What used to take multiple emails now happens in minutes.

Custom Cable Configurator

Since 1952, Harwin has been an industry leader in electrical connectors used in spacecrafts, airplanes, and electric vehicles, to name a few. We’ve established a relationship with Harwin over the last few years to become their digital partner, pushing their digital presence to new levels and enabling their business to grow through a powerful, fully integrated website.We continue to work with Harwin to push and develop their Salesforce website integration, always looking for growth opportunities and areas of improvement.

If your business relies on SaaS systems, we can integrate them directly into your app. Using our <a href="https://sidigital.co/faraday">Faraday middleware</a>, we connect tools like <a href="https://sidigital.co/services/integrate/salesforce">Salesforce</a>, bespoke internal systems, and <a href="https://sidigital.co/services/integrate/payment-gateways">payment platforms</a> with your app, so data flows seamlessly and you avoid the headaches of manual workarounds.

Our app development team builds our apps using React Native, so they work across iOS and Android. Our hybrid approach provides great flexibility and means there’s only one codebase to maintain, so there’s less ongoing maintenance, so you can focus your efforts on one app, not two.

Most of our clients come to us with systems already in place: a CRM here, a <a href="https://sidigital.co/services/integrate/payment-gateways">payment gateway</a> there, maybe an ERP that's been running for years. Payload's API plays nicely with all of them. Paired with <a href="https://sidigital.co/faraday">our own Faraday middleware</a>, we can connect your website or app to virtually any third-party system. Your data flows where it needs to, when it needs to.

Nobody wants to rebuild their website every few years. Payload is built on TypeScript and Node, which means it's not going anywhere. It receives regular updates, stays secure, and won't leave you stranded on outdated technology. We build sites that last.

Businesses change. Your website should keep up. Payload's content modelling makes it straightforward for us to add new features, fields, or entire sections without starting from scratch. Your site scales with you, not against you.

Payload is self-hosted, which means your data stays under your control. There's no third-party service holding your customer information. For clients <a href="https://sidigital.co/services/support/hosting-and-data-security">handling sensitive data</a>, this is often the deciding factor.

Slow websites lose visitors. Studies show over half of mobile users leave if a page takes more than three seconds to load. Payload, combined with Next.js, delivers content fast. Your users get where they want to be quickly, and your editors spend less time waiting for the backend to catch up.

We use TypeScript across our Payload builds. It catches errors early, keeps code clean, and means fewer bugs down the line. The result is a more reliable, maintainable website.

Payload comes with built-in SEO tools that are genuinely useful. Meta descriptions, custom images, preview panels showing how your pages will appear in search results. It's easy for your team to optimise content without needing a developer.

Because we build everything from scratch, the features we include are shaped entirely by what you need. <a href="https://sidigital.co/services/discover">During discovery</a>, we'll dig into your challenges and workflows, then design a solution that fits your business like a glove. No compromises, no workarounds.

We don't just fix today's problems and call it done. When we scope your project, we're thinking about where your business is heading. That means your software can grow and expand alongside you, without needing a complete rebuild when things change.

A bespoke platform to allow the public to submit toy invention ideas.

Hasbro wanted to do something unusual in the toy industry: open their invention process to everyone, not just professional inventors. We designed and built a platform where anyone with a toy or game idea can submit it directly to Hasbro's team.From brand identity to visual design to the platform build, we created an experience that makes the submission process feel accessible and inspiring. The platform handles everything from idea submission and evaluation to secure IP management, giving Hasbro a streamlined way to discover the next generation of toys.

Hasbro’s new platform needed to integrate with the existing professional inventors platform we’d built for them.

We'd previously built Hasbro's platform for professional inventors. The new public submission system needed to integrate seamlessly with that existing workflow.Public submissions flow into the same external inventor management platform, where Hasbro's team reviews and evaluates all ideas in one place. This unified system means promising concepts from public inventors get the same consideration as professional submissions.

Bespoke Integrations

Established in 1923, Hasbro are one of the worlds largest children’s toy manufacturers, with brands such as Monopoly, Dungeons & Dragons and Peppa Pig part of their vast portfolio.We’re been working with Hasbro for over a decade, and we continue to work with them to allow inventors and creators across the globe to submit their creations to Hasbro, allowing their portfolio of games to continue to grow.

We build bespoke websites and apps, backed by 20+ years of development experience and a UK-based team of developers ready to bring your project to life.
