[resenha] IPhone apps that identify radars on Brazilian roads

Speed ​​controllers

We tested some applications that warn about speed control points on Brazilian roads. Of course, it was not possible to test them in all regions of the country and ideally, you should try them out in your city first before trusting 100% in the results of the program.

Let’s talk about three of them, well known to the community: Trapster, iRadar and Lynx GPS.


We already talked about the Trapster still in October last year. Since then, the country’s radar coverage map has increased dramatically.


The strength of the utility is the settings, graphics and flexibility. The radar location is updated by the users themselves, which can be good or bad, depending on how much they dedicate themselves. Despite this, in our tests all sparrows were identified.


The big weakness is that it depends 100% on the internet, since all maps and radar locations are obtained on the web in real time. There is also no version in Portuguese, only in English. There is a vocal warning alert, which is a little low in our opinion.

Radar Map

It was designed with the principle of community collaboration, where everyone can help inform where the radars are, instantly updating for all other Trapster users. It does not only run on the iPhone, but also on several other cell phones, which further increases the number of participants.

iRadar Brasil

Simplicity is the key to the success of this application, which for weeks has ranked the first position in the Brazilian ranking of paid apps. It has two basic modes of operation, viewing only the list of nearby cameras, or with Google Maps style map, indicating the cameras.


The first option works without internet access. The camera list is stored internally with the geographical position of each one, and can be updated by the iPhone itself, with just one click (in this case, it accesses the data network). This is great as it is easy to keep up with new radars. To view maps, he needs to search the web, as he does not have all the maps integrated.


The configuration options are good, with emphasis on adjusting the distance to activate the speed control proximity warning. It is not just radars that appear, but also police stations and electronic speed bumps. Unfortunately the alert sound is very bad, it is short and low, often looking like a new message on the cell phone. Another weird bug is that it lists the radar, but even after you pass, it remains on the list, with the distance increasing as you move away from it. Although you don’t need Internet access, it takes up almost nothing in the device’s internal memory.

Lynx GPS

Another speed controller that could not fail to participate in the test is the Lynx GPS, from Robotron.

Lynx GPS

It signals the speed control points, giving the warning before reaching the point of interest. You can adjust this warning by time, not distance, so it will calculate based on your speed the right time to give the warning.

Adjusting warnings

The application can be downloaded for free, but it works with a subscription system. The first month is free and then, if the user likes the app, they will need to subscribe for one year (R $ 130) to continue using Lynx. There you can always update the control points directly from the Robotron website.

Download of control points Covered cities

The service currently serves only 11 cities: Brasília, Goiânia, Campinas, São Paulo, Curitiba, Florianópolis, Recife, Fortaleza, Rio de Janeiro, Belo Horizonte and Porto Alegre.

The ideal is to install the application and test it well to decide if in your region it works or not.
