### 5/5 — Fun even outside of O-chem

*2024-07-29, version 1.0.5*

I forgot I had this on my phone and then started playing with it again. The fun animations sucked me in and I found myself watching so many of them. It’s been years since I took O-chem.

### 5/5 — Such a great app!

*2023-03-21, version 1.0.4*

The transition states, trajectories, and reactions found here are great. Very accurate models. I plan on using this often!

### 5/5 — nice

*2022-10-30, version 1.0.1*

this app helps me visualize the molecular structure better! thanks so much :)
