Conclusion: The Cobra iRadar system updates the venerable radar detector concept by adding a smartphone app component, albeit with mixed results.
Pros: Simple, well-designed app interface. Detects X, K, and Ka bands as well as laser. Clear alerts are easy to understand. Worked seamlessly in testing.
Cons: Crowd-sourced user reports generate way too many false alarms. Could use more range for Ka band. Aside from the interface, the app adds little in the way of actual functionality over a traditional radar detector.
