I would say it does use data. However, since it only uses it while we are speaking, I do not think it is a heavy use app. Twoblindsheep and I had a 20 minute call yesterday. It barely registered. I will track it to see when I am using it.
If not, I will have walkies as well. Put them on the chargers today.
