Verdict
The clearest difference is in-app purchases: TimeCalendar at none against NaturaList's 3. TimeCalendar also leads on review sentiment (55% vs 32%) and iOS requirement (10.0 vs 12.0). NaturaList's advantage is update cadence (every 2 months vs every 10 months). On price, ads and device support there is nothing between them.
