Great app besides one bug

The app is great but one glaring issue is that the app seems to recognize molecules that are “close enough” as a correct answer. What makes it worse is that you can’t go back and fix the structure you drew without having to reset EVERY SINGLE SAMPLE. Please fix this, it shouldn’t be recognizing the wrong molecule as the right answer

Great app

A very intuitive and fun way to learn spectroscopy. Should be a useful tool for chemistry students at all levels, especially organic chemistry.

The app crashes every time I open it.
