Verdict
The clearest difference is ads: Pi Design at none against Vertical Calendar's shown. Pi Design also leads on monetization model (free vs ad-supported) and iOS requirement (15.1 vs 26.0). Vertical Calendar's advantage is ratings volume (8 vs 1). On price, rating, review sentiment and in-app purchases there is nothing between them.
