Verdict
The clearest difference is ads: Barometric Pressure at none against Professional Barometer's shown. Barometric Pressure also leads on update cadence (every 5 days vs every 42 months) and review sentiment (61% vs 45%). Professional Barometer's advantage is monetization model (ad-supported vs free with in-app purchases). On price, rating, in-app purchases and device support there is nothing between them.
