Verdict

The call

The clearest difference is ratings volume: Calendars at 122K against PolyPlan's 101. Calendars also leads on rating (4.7 vs 4.5) and chart position (#107 vs unranked). PolyPlan's advantage is iOS requirement (16.6 vs 18.2). On price, update cadence, ads and in-app purchases there is nothing between them.
