Verdict
The clearest difference is ads: Barometer at none against Professional Barometer's shown. Barometer also leads on update cadence (every 5 days vs every 42 months) and review sentiment (62% vs 45%). Professional Barometer's advantage is rating (4.2 vs 3.7) and monetization model (ad-supported vs free with in-app purchases). On price, ratings volume, in-app purchases and device support there is nothing between them.
