Verdict

The call

The clearest difference is rating: CSI CloudPro at 5.0 against NEPViewer's 2.3. CSI CloudPro also leads on iOS requirement (13.0 vs 15.0). NEPViewer's advantage is update cadence (every 3 weeks vs every 2 months) and ratings volume (4 vs 1). On price, review sentiment, ads and in-app purchases there is nothing between them.
