Verdict
The clearest difference is in-app purchases: Brainwave Visualizer at none against UTM SE's 3. Brainwave Visualizer also leads on iOS requirement (7.1 vs 15.0). UTM SE's advantage is update cadence (every 4 months vs every 42 months) and ratings volume (561 vs 7). On price, rating, review sentiment and ads there is nothing between them.
