# OpenEvidence vs NeuroStudy

The clearest difference is in-app purchases: OpenEvidence at none against NeuroStudy's 1. OpenEvidence also leads on ratings volume (12K vs 2) and update cadence (weekly vs every 4 weeks). NeuroStudy's advantage is review sentiment (100% vs 81%). On price, rating, ads and device support there is nothing between them.

Both are free to download. NeuroStudy sells 1 one-off in-app purchase. OpenEvidence asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.9 for OpenEvidence against 5.0 for NeuroStudy. That said, the two scores are not equally well evidenced: OpenEvidence has 12K ratings behind it against 2, so its average is the more settled of the two. Written reviews are what separate them: 81% of OpenEvidence's written reviews are positive against 100% of NeuroStudy's.

OpenEvidence ships an update weekly, NeuroStudy every 4 weeks. The most recent releases landed on November 11, 2026 and November 8, 2026 respectively.
