Variant Systems

React Native for Logistics

Your drivers use iPhones and Androids. React Native ships one app that works on both.

Variant Systems builds industry-specific software with the tools that fit the problem.

Why this combination

  • Single codebase deploys to iOS and Android devices used by field teams
  • Native camera and Bluetooth access for barcode scanning and device pairing
  • Offline-first architecture keeps apps functional in warehouses and dead zones
  • Push notifications drive real-time dispatch updates and delivery alerts

Why React Native for Field Logistics

Logistics happens in the field. Drivers deliver packages. Warehouse workers scan barcodes. Dispatchers coordinate from tablets. These teams use a mix of iOS and Android devices, often personal phones in smaller operations. Building separate native apps for each platform doubles your cost and means features ship at different times to different teams.

React Native gives you one codebase that runs on both platforms. Your driver app works on a $200 Android phone and the latest iPhone. Native module access means barcode scanning uses the device camera at full speed, GPS tracking runs in the background efficiently, and push notifications arrive instantly. For logistics companies managing thin margins, the cost efficiency of a single development team maintaining one codebase is significant.

Driver and Delivery Applications

A driver app needs to do a lot without getting in the way. Display the next delivery. Show the route. Let the driver confirm arrival. Capture a signature. Take a photo. Move to the next stop. All of this should take seconds, not minutes. Complicated interfaces cost you deliveries per hour.

We build driver apps with React Native that prioritize speed and simplicity. The route screen shows the optimized sequence with turn-by-turn navigation integrated via native map SDKs. At each stop, the driver taps to confirm arrival - GPS coordinates stamp the event automatically. Signature capture uses a native canvas component. Photo proof of delivery stores locally and syncs when connectivity allows. Delivery exceptions (damaged goods, refused shipment, wrong address) follow structured flows that capture the right data without requiring the driver to type paragraphs.

Offline-First for Real-World Conditions

Logistics apps operate in warehouses with poor signal, rural delivery routes with no coverage, and loading docks where phones barely connect. An app that requires constant connectivity isn’t a logistics app. It’s a liability.

React Native’s offline-first architecture stores the day’s manifest locally at the start of each shift. Route data, customer information, and delivery instructions are all available without network access. As drivers complete stops, events queue locally with timestamps and GPS coordinates. When connectivity returns, the sync engine pushes completed events and pulls updates - new stops added, sequence changes, cancellations. Conflict resolution handles the case where dispatch modified a route while the driver was offline. The driver’s work is never lost, and the system reconciles state cleanly.

Warehouse and Scanning Operations

Warehouse operations run on scanning. Receive a shipment - scan every box. Put items on shelves - scan the location. Pick an order - scan each item. Load a truck - scan to confirm. Every scan is a data point that maintains chain of custody and inventory accuracy.

React Native accesses the device camera natively for barcode and QR code scanning. We integrate scanning libraries that handle Code 128, QR, DataMatrix, and other common logistics formats. For high-volume operations, the app pairs with Bluetooth ring scanners and sled scanners via native module bridges. Scan results validate against expected manifests in real time - the app immediately flags if a wrong item was picked or a shipment is short. Inventory counts sync to your warehouse management system in the background, keeping stock levels accurate without manual reconciliation.

Compliance considerations

Chain of custody timestamps with GPS coordinates for proof of delivery
Tamper-evident photo capture for damage documentation
Offline data encryption for shipment information stored on device
Driver identity verification via biometric authentication

Common patterns we build

  • Driver delivery apps with route optimization and turn-by-turn navigation
  • Warehouse barcode and QR scanning with inventory sync
  • Proof of delivery with signature capture, photos, and GPS stamps
  • Real-time dispatch boards with push notification alerts
