Verdict
The clearest difference is price: Log at Free against Warp Visualizer's $19.99. Log also leads on review sentiment (100% vs 75%) and update cadence (every 3 weeks vs every 4 months). Warp Visualizer's advantage is iOS requirement (16.0 vs 18.0). On rating, ratings volume, ads and in-app purchases there is nothing between them.
