Google Play Internachi Training Cards

I got a new phone and went to add the training cards app I had on my old android phone, but couldn’t find it in the Google Play store. Have they been discontinued or renamed? I thought it was a pretty helpful resource you could plug away at when you had time. Great prep item.

I can see it for the apple App Store when searing “nachi flash cards” 3rd item down. Not sure on google play.
