# CRISPR vs BioViewer

The clearest difference is rating: CRISPR at 4.8 against BioViewer's 1.0. CRISPR also leads on review sentiment (50% vs 33%) and ratings volume (12 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

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

CRISPR holds the better App Store score, 4.8 against 1.0.
