Verdict

The call

The clearest difference is rating: Windy.com at 4.8 against 知天气's 4.3. Windy.com also leads on ratings volume (80K vs 3) and update cadence (every 3 weeks vs every 2 months). 知天气's advantage is in-app purchases (none vs 10) and iOS requirement (11.0 vs 16.0). On price, ads and device support there is nothing between them.
