Verdict

The call

The clearest difference is rating: I at 5.0 against i's 2.3. I also leads on review sentiment (50% vs 15%) and update cadence (every 9 days vs every 3 months). i's advantage is ratings volume (789 vs 5). On price, ads, in-app purchases and monetization model there is nothing between them.
