Verdict

The call

Calendar and Structured both sit at 4.9 stars, but that hides the real split: 78% of Structured's written reviews are positive against 36% of Calendar's. Structured also leads on update cadence (every 9 days vs every 4 months) and chart position (#96 vs unranked). Calendar's advantage is in-app purchases (none vs 10) and ratings volume (1.5M vs 169K). On price, rating, ads and device support there is nothing between them.
