Metal Detector App Development: A Mobile App That Connects to Your Device

If you manufacture detectors, I build the mobile app that connects your device to the phone, shows the signal live and guides the user in the field.

Quick answerMetal detector app development covers the communication between the detector's control board and the phone, processing the incoming measurements and presenting the results on a clear screen. I built this end to end for the HS Detector app: signal strength, oscilloscope, depth estimate and target type appear live on the phone. I use the same approach to build an app for your own device.

Who is it for?

Companies that design or manufacture their own detectors, makers who want to add a phone screen to an existing device, and detector retail brands. If your device has a small screen or none at all, the phone becomes a full control panel and your product stands out at first glance.

Main page for this topic: HS Detector Mobile App

What I build

  • Device–phone communication: data protocol with the control board and a real-time data stream
  • Live scan screen: signal gauge, status messages, signal history
  • Oscilloscope view: pulse decay curve and sampling point
  • Depth and target: depth estimate per coil type, target classification by conductivity, alerts
  • Map, log and settings: a tabbed interface usable one-handed in the field

See the HS Detector mobile app as an example.

A developer who understands the hardware

A detector app is not just a nice screen; it needs software that understands pulse rate, sampling timing, coil type and battery state. I have been building electronics and software together for 18 years; because the same person designs the embedded board and the mobile app, protocol and screen fit each other.

For the signal processing side, see pulse induction detector software.

How we proceed

We first discuss your device's board, its data output and the screens you want. We define the communication protocol, test the live signal screen with your device in the first version, then add depth, target and logging features in stages. I also handle the App Store release.

Frequently asked questions

Do you develop metal detector apps?

Yes. I build mobile apps for detector manufacturers that connect to the device and show the signal live; the HS Detector app is my reference project.

Can an app be added to my existing detector?

Yes, if your board provides a data output. I first review the board and data format and build the communication protocol accordingly.

Which screens does the app include?

Live scan, signal history, oscilloscope, depth and target display, plus map, log and settings tabs; we define the scope for your device.

How does the process work?

We define the scope together, test the live signal screen with your device in the first version and add further features in stages.
