GeoGeek AR is basically a quiz game. Players have to identify places by tapping on the globe. Questions are presented in two ways. The first is simply the name of a place appearing on screen followed by the prompt to tap on the globe to identify where you think that place is. The second way questions are presented is with a place being highlighted on the globe and then a list of four multiple choice options from which to pick.
Applications for Education
GeoGeek AR doesn't require you to register in order to play. That can make it a good option for use on shared classroom iPads. Overall, it's a fun little game for practicing place identification.
