I have the iOS version before I swapped to Android. I like the integration on the phone as far as seeing traffic cams and speed traps, however Trapster is better for the speed traps as it updates way faster. As for radar detection..... It sucks pretty bad. It works in my county for the Sheriff's office and local PD, however it does not work when I go out of county, or for state police. It just doesn't detect enough newer bands.
The range on the detection is also pretty small. It works fine for city driving where you're going 35-40 or less, but at highway speeds, it doesn't detect anything till after you can visually see the Officer on your own, and by then it's generally too late unless there is heavy traffic around you.
So overall I would NOT recommend it, and agree with Cadzilla74 on just investing in a better one. They are more expensive, but they pay for themselves the first time you avoid a ticket with it.
