3D Brain

It’s bad app because after I paid, I cannot open app anymore. I don’t know what happened with the app.

I purchase this app and i think it will be HD images but it doesn’t different from free version.

Great for free apps

I have been using this app for two years. When I saw there was an upgrade, I upgraded. Unfortunately, ever since the upgrade, the app will not even open, it just crashes immediately. So like many here, I have paid to upgrade a product which no longer functions. So, as many reviews state, I paid to upgrade, and now have an app that is utterly unusable. Please respond.

It seems like a very useful app but I paid for premium and it stopped working and crashes on start up

It would have been nice to have been notified that it would no longer work on my phone before it took my 99c to upgrade. I’m happy to donate, I really enjoyed using this while it worked.

I used to use the basic version it was working fine, when I tried using it again for my class, it asked for an upgrade to support the students and the teachers and the developers, I paid and since then it doesn’t open. I tried multiple times it still kicked me out. Please fix it!

i learned so much about the brain with this app. it helped me pass the AP psych exam !

I purchased this app and every time I open it it crashes and closes. This didn’t happen until I bought the in app purchase. I can’t open the app to discontinue it so I’m basically paying for an app I can’t even use!

I’ve discovered the insula is missing?
