Do you use a telemetry/UDP app?

I'm on PS4, I would like to find a decent app for my laptop while I race.  What is a good(preferably free) app that would be easy to set up?

SO I've downloaded 3 different UDP Telemetry apps onto my computer.  One of the apps was free(telemetry_V7.1), and the other two were paid(RS Dash & Sim Racing Telemetry).  As a newb sim racer, I'm checking them each out.  They each are good in there own different ways.  I might post another thread in the future about them as far as info or an informal review.  But for now, I'm a newb just checking them out, and I if I can help someone with questions on what they are like before your purchase or downoad, feel free to ask me and I"ll do my best to answer your question.
