Verdict
The clearest difference is rating: i at 2.7 against Arrowmax's 1.8. i also leads on ratings volume (35 vs 5). Arrowmax's advantage is update cadence (every 2 months vs every 14 months) and iOS requirement (12.0 vs 16.0). On price, review sentiment, ads and in-app purchases there is nothing between them.
