Verdict
The clearest difference is review sentiment: Joylog at 100% against i's 7%. Joylog also leads on rating (4.0 vs 1.8) and iOS requirement (10.0 vs 15.0). i's advantage is update cadence (every 3 weeks vs every 4 months) and ratings volume (26 vs 5). On price, ads, in-app purchases and monetization model there is nothing between them.
