Verdict
Calendars and Smart Tasks both sit at 4.7 stars, but that hides the real split: 79% of Smart Tasks's written reviews are positive against 56% of Calendars's. Calendars's advantage is ratings volume (123K vs 4.5K) and chart position (#136 vs unranked). On price, rating, ads and in-app purchases there is nothing between them.
