There is no hug button on Tapatalk, at least not the free version I use once in awhile. The "thanks" shows up as a heart to click and I see the number of them, such as a heart with a 2 next to it. So that post got 2 thanks, but I don't think I can see who gave them.
If you give a thanks, it appears in another color than thanks from other members.
I haven't used them it in awhile because it's slow and I don't have a strong enough connection to make it load faster.
