Case Study — Connected Hardware

The app and backend behind abiometric-authorized firearm.

LodeStar set out to build a firearm that works only for its owner. Xari designed and built the mobile app and the backend that bring it to life — and kept them in lockstep with the hardware and firmware team so the whole system works as one.

The Role

We owned the software.

Xari led the software side of the product end to end — the mobile app owners carry, the backend and cloud services behind it, and the connection between the app and the firearm. We worked shoulder-to-shoulder with the hardware and firmware team so the result feels like one product, not a device with an app bolted on.

The Challenge

A connected system, not just an app.

The firearm, its charging dock, the firmware, and the mobile app all have to work together — every time. Pairing had to be reliable. App behavior had to stay perfectly aligned with the hardware. And the whole experience had to stay calm and immediate in the owner's hands, in real conditions, not just on the bench.

The Work

What Xari built.

Mobile app — iOS & Android

The app owners use to set up, monitor, and manage their firearm.

Backend & cloud services

The services behind the app — accounts, devices, and everything the product needs to run reliably at scale.

Real-time device connectivity

A dependable link between the app and the firearm, tuned to stay stable in the real world.

Multi-user, multi-device

Built for households and teams: multiple users, multiple devices, one coherent experience.

App–firmware coordination

We kept app behavior aligned with the firmware team’s logic through rapid, hands-on validation cycles.

Reliability, proven in the field

Refined with real users in real conditions until the technology stays completely in the background.

The Product

Engineered to feel like one product.

The result is a connected firearm where the software disappears. Owners get reliable, immediate access when they need it — and never have to think about the technology making it happen.

The App

Everything the owner needs, in one place.

From the app owners carry, they set up the charging dock, check status and battery at a glance, enrol fingerprints, and manage who's authorized — a calm, focused experience that gets out of the way. Designed and built by Xari for iOS and Android.

The firearm beside its companion app — sign-in, status and battery, fingerprint enrolment, keypad setup and dock setup all live in the app shown above.

On a firearm, security isn't a feature you add later. It's the first decision, and every line of code answers to it.
