Verdict

The call

The clearest difference is in-app purchases: Calendar at none against Calendars's 20. Calendar also leads on ratings volume (1.5M vs 123K) and iOS requirement (10.0 vs 18.2). Calendars's advantage is update cadence (weekly vs every 4 months) and review sentiment (56% vs 36%). On price, rating, ads and device support there is nothing between them.
