Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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. That said, the two scores are not equally well evidenced: CRISPR has 12 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 50% of CRISPR's written reviews are positive against 33% of BioViewer's.
CRISPR ships an update every 2 weeks, BioViewer every 9 days. Both last shipped on November 3, 2026.
