I love the physical games of this series, but these digital implementations have serious problems. For example: I have my devices set to use English as the system language. When you launch the app, the main screen is in English, but if you want to login to your account and enter your email, the verification page is in German. Fortunately I lived in Germany for aeveral years and can read the page, but this shows very poor QA on your end. And ALL of these three apps have the same problem. Also, the rules page has several grammar and spelling problems and it shows poor translation. For example, the English name for the app is Clever Cubed, but the rules page says “Clever High Three”, which is a transliteration of “Clever Hoch Drei”. Very, very poor QA on these apps
