Verdict

The call

The clearest difference is in-app purchases: PlanPop at none against Calendars's 20. PlanPop also leads on review sentiment (89% vs 56%) and update cadence (every 2 days vs weekly). Calendars's advantage is ratings volume (123K vs 1K) and chart position (#107 vs unranked). On price, rating, ads and iOS requirement there is nothing between them.
