Verdict
The clearest difference is rating: i at 2.1 against i4Flash's 1.4. i also leads on ratings volume (80 vs 12). i4Flash's advantage is update cadence (every 2 weeks vs every 3 months) and iOS requirement (9.0 vs 11.0). On price, review sentiment, ads and in-app purchases there is nothing between them.
