Requirement of Garmin for using Aeropod

[nikshar]

I'm using my aeropod in profile 4 with a Garmin watch. It doesn't support the Aeropod 2.0 app, so I'm using the older one.
But then I wonder if I even need the app installed? If I'm just interested in collecting data, is it enough if I just pair my watch with aeropod, start the ride on the watch and do the lap markers, without needing the app? To further that, would it work if I just use my Wahoo and connect with the aeropod and do the lap markings?
