Intelli vs Kopperfield
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Intelli
This application allows users to communicate with an AFCI breaker via Bluetooth. It provides diagnostic measurements, setup options, and the ability to view load waveforms, mimicking oscilloscope functionality. This eliminates the need for a physical oscilloscope when troubleshooting electrical loads.
- Bluetooth communication with AFCI breaker
- Basic diagnostic measurements
- Setup and view load waveforms
- Mimics oscilloscope functionality
- Troubleshooting electrical loads
- Arc detection algorithm improvement

We have developed an AFCI breaker which we are able to communicate with this app via bluetooth. Apart from providing basic diagnostic measurements for this breaker, the App also provides a way to setup and view load waveforms seen by the breaker mimicking the oscilloscope functionality. The App when combined with a breaker with BLE communication, eliminates the need for a physical oscilloscope while troubleshooting or diagnosing problematic electrical loads. Engineers are able to use this app to diagnose why a tripping event is happening and to also improve arc detection algorithm.
