# Biology3D vs CellWalk

The clearest difference is in-app purchases: Biology3D at none against CellWalk's 3. Biology3D also leads on update cadence (weekly vs every 3 weeks) and iOS requirement (9.0 vs 27.0). CellWalk's advantage is ratings volume (72 vs 1). On price, rating, ads and device support there is nothing between them.

Both are free to download. CellWalk sells 3 in-app purchases, starting at $9.99 per month. Biology3D asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for Biology3D against 4.9 for CellWalk. That said, the two scores are not equally well evidenced: CellWalk has 72 ratings behind it against 1, so its average is the more settled of the two.

Biology3D ships an update weekly, CellWalk every 3 weeks. The most recent releases landed on September 30, 2026 and October 25, 2026 respectively.
