Verdict

The call

The clearest difference is rating: i at 2.8 against i's 2.3. i also leads on update cadence (every 5 weeks vs every 3 months). i's advantage is ratings volume (789 vs 23) and iOS requirement (8.0 vs 10.0). On price, review sentiment, ads and in-app purchases there is nothing between them.
