Verdict

The call

The clearest difference is in-app purchases: Chrono at none against JotDay's 4. Chrono also leads on rating (5.0 vs 4.7) and review sentiment (100% vs 85%). JotDay's advantage is ratings volume (21 vs 1) and update cadence (monthly vs every 3 months). On price, ads, device support and iOS requirement there is nothing between them.
