Verdict

The call

The clearest difference is in-app purchases: AirWeatherHelper at none against DustMap's 4. AirWeatherHelper also leads on ads (none vs shown) and update cadence (every 2 days vs every 5 months). DustMap's advantage is device support (3 vs 1) and iOS requirement (15 vs 17.6). On price there is nothing between them.
