Companion App Development

We build mobile and web applications that talk to hardware. If your device needs a companion app for setup, control, or data visualization, we handle it—Bluetooth pairing, Wi-Fi provisioning, cloud sync, firmware updates, App Store submission. The whole stack.

Most app development shops don't understand hardware. They build pretty interfaces that break when Bluetooth reconnects or data arrives out of order. We build apps alongside firmware, so we catch these problems before they ship. When your user taps a button, the device actually responds.

Companion apps fail when the app team doesn't understand the hardware. We build apps alongside the firmware, so Bluetooth pairing actually works, data syncs reliably, and edge cases get handled. We've shipped apps that talk to BLE devices, Wi-Fi-connected hardware, and cloud-bridged systems.

When you hand us the app, you're not managing a translation layer between two teams—we own the whole connection. We define the BLE characteristics, write the firmware that implements them, and build the app that uses them. And if you need the hardware designed too, our electronics team handles that.
