Verdict
The clearest difference is in-app purchases: Wind Vectoriser at none against PD Altitude's 1. Wind Vectoriser also leads on iOS requirement (12.0 vs 16.0). PD Altitude's advantage is update cadence (every 4 weeks vs every 20 months). On price, ads and device support there is nothing between them.
