Aa: While I am just an observer in this, I do have an opinion. I have watched your videos and think it looks like a useful experience. The thing is, two developers can come up with the same type of app around the same time. There are a few various biology apps that came out that each fill a role in learning. I would not say they copied ideas from each other just because they cover much of the same content. Just like all the flight sim and racing games made for VR. Plus if you did have some reason to believe the content was "stolen", you are not proving anything with an all caps rant. Speak calmly and offer some form of proof. There is room for educational apps that cover the same subjects.
