double sided business card holder
While the app is generally fun, I've experienced lag that can make playing frustrating at times. The notifications for daily rewards are helpful, but they can clutter the notification bar. I’ve had to reconnect to the server a couple of times during a match, which disrupts my concentration. The feature that allows you to review past games is great for learning, though I wish it was easier to access. Overall, this card game app has a lovely design, but it could benefit from a few bug fixes and improvements in connection stability.
