I just picked up a near new 2019 Trek Dual Sport 3, It came with the DuoTrap S already on it. I do like the clean look of using it vs. the zip ties and straps for the other units so I'd like to use it but i'm unsure of the best route to go. Whats the cheapest (but still decent) computer I could get that would be compatible? I'm not a hardcore rider, I'd like to see speed, distance and time as I'm riding and then have something I could easily upload to my phone. I'm not opposed to going just with my phone and getting a handlebar mount, but if I could keep that in my seat bag I'd be fine. I'm thinking something along the lines of the Garmin 25, but even then I'm paying for the sensors I wouldn't necessarily need.

Is there an app that connects directly to the DuoTrap S? It looked like at one point Strava did, but thats not the case any longer. Does the Garmin Connect app? (I'd think no since its a competing brand).
