# 3D Molecule Viewer vs Unreal Chemist

The clearest difference is rating: Unreal Chemist at 4.5 against 3D Molecule Viewer's 3.0. Unreal Chemist also leads on ratings volume (68 vs 2). 3D Molecule Viewer's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price, update cadence, device support and iOS requirement there is nothing between them.

Both are free to download. Unreal Chemist sells 1 one-off in-app purchase. 3D Molecule Viewer asks for nothing beyond the download.

Unreal Chemist holds the better App Store score, 4.5 against 3.0. That said, the two scores are not equally well evidenced: Unreal Chemist has 68 ratings behind it against 2, so its average is the more settled of the two.

3D Molecule Viewer ships an update every 9 days, Unreal Chemist every 2 weeks. The most recent releases landed on October 13, 2026 and October 20, 2026 respectively.
