Not perfect but worth the cost!

I dont write a lot of reviews but I absolutely support this app and I think you should too.

This app isnt perfect but what it is trying to achieve pushes the bounds of the technology for a scientific purpose. It also has amazing educational possibilities.

The price is the lowest one can charge for an app and I truly believe money should go to fund a project like this.

Kudos to the dev team.
