Verdict

The call

The clearest difference is update cadence: PDF AutoScroll at every 2 weeks against Vertical Calendar.'s every 2 months. PDF AutoScroll also leads on rating (4.3 vs 4.0). Vertical Calendar.'s advantage is price ($1.99 vs $5.49) and iOS requirement (13.0 vs 16.6). On review sentiment, ratings volume, ads and in-app purchases there is nothing between them.
