### 1/5 — Someone remake this app

*2024-12-23*

App crashes, accepts incorrect answers as correct, very limited, should be free to access all content. Do not recommend

### 4/5 — Great app besides one bug

*2023-11-13*

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

### 1/5 — Has problems

*2022-10-05*

The app is saying i have created the molecule correctly, but it clearly is in the wrong order…

### 1/5 — Terrible

*2022-06-10*

The app crashes every time I open it.

### 5/5 — Great app

*2018-12-28*

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