### 1/5 — Doesn’t work at all

*2024-10-15*

The first molecule the app shows upon launching is methane, and the 3D model is wrong; it’s supposed to be tetrahedral and is instead depicted as square planar. The carbon molecular bonds in CH4 are sp3 hybridized. Fix the 3D model.

Moreover, I cannot search for any chemical. The app is completely frozen on methane. I restarted the app with no success.

The idea for the app is great, but the execution is abysmal. Please put some work into this app and I will redownload it and update my review.

### 5/5 — Fell in love with Chemistry
