# Cellvizio® vs OpenEvidence

The clearest difference is update cadence: OpenEvidence at weekly against Cellvizio®'s every 11 months. OpenEvidence also leads on ratings volume (12K vs 6) and chart position (#22 vs unranked). Cellvizio®'s advantage is review sentiment (100% vs 80%) and iOS requirement (13.0 vs 15.1). On price, rating, 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.

On the App Store both sit at effectively the same score — 5.0 for Cellvizio® against 4.9 for OpenEvidence. That said, the two scores are not equally well evidenced: OpenEvidence has 12K ratings behind it against 6, so its average is the more settled of the two. Written reviews are what separate them: 100% of Cellvizio®'s written reviews are positive against 80% of OpenEvidence's.

Cellvizio® ships an update every 11 months, OpenEvidence weekly. The most recent releases landed on September 23, 2026 and September 26, 2026 respectively.
