User reviews

Purchase required to use app

Played online a few times and was curious if there was an app. Downloaded app but there is no option to do anything on the app without paying the subscription (which is pricey as it is).

Some of the features on app might be something I’d pay for down the road if me a friends got invested in this or if features could allow for a fun game night thing like Quiplash or Kahoot. But cannot get past the subscription price and the app being useless unless you pay up.
