# Chem AI vs Molecule Geometry 3D

The clearest difference is in-app purchases: Molecule Geometry 3D at none against Chem AI's 4. Molecule Geometry 3D also leads on rating (5.0 vs 4.7). Chem AI's advantage is ratings volume (93 vs 1) and device support. On price there is nothing between them.

Both are free to download. Chem AI sells 3 in-app purchases, starting at $2.99 per 7 days. Molecule Geometry 3D asks for nothing beyond the download.

Molecule Geometry 3D holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Chem AI has 93 ratings behind it against 1, so its average is the more settled of the two.
