Frustrated mom – Monster Math : Kids Fun Games Review

I really like this app my 9 year old does as well. But why are there so many versions of this app? I am sure that I have gotten at least 5 of these apps. When I open them they all have the same story line and capabilities. Now I am having to figure out which to remove so I do not remove his progress. Please have different characters or storyline for new apps (with connecting accounts) or just pick one and update.
