Verdict

The call

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.
