# atom.sim vs 3DMolecule

atom.sim and 3DMolecule are too close to call on the numbers: across 4 compared parameters — price, in-app purchases, device support and iOS requirement among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
