Champion Nishikigoi review for Smart Visual Search

This app still needs a lot of work. Upon installing I was already hit with an error. Closing the app and reopening then brought me to the main app page which asks me to sign up for a subscription before even proving that this app works. I sign up for the subscription and then try using the app by first syncing my products, but hitting the sync button doesn't seem to do anything. It seems that the developers have given up on this app which is unfortunate since there are few apps like this in this space.
