I find it interesting that, although each app serves the same purpose, they have very different user experience, interface, communities, and sellers. I would love to hear from the card community on this subject! Do you use any of these apps? If you use multiple, what are some differences you notice? What do you like and dislike about each? Are these apps moving the hobby in the right direction?
Lastly, what do you feel draws you back as a user? What would make you delete the app? I'm all ears! I'm excited to hear from the community on this matter!
