### 5/5 — Needed tool

*2025-02-05*

After my first few spoofings and jam, it’s very nice to be able to plug in a radial DME and see what is happening behind the scenes.  

It would be nice if it alerted to possible spoofing better 

 I’m surprised this tech isn’t built into foreflight or Jepp.

### 4/5 — Useful aid

*2024-04-30*

Found it useful when spoofed over Saudi/Egypt. Would like the ability to delete individual fixes if input incorrectly.

### 5/5 — Needed tool

*2024-04-24*

Haven’t been spoofed with the app yet, but installed on all EFBs.
 I’m surprised this tech isn’t built into foreflight or Jepp.
