Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

Professional Barometer holds the better App Store score, 4.2 against 4.0. Both are backed by a comparable volume of ratings — 57 and 17 respectively.
