# Barometric Pressure vs Professional Barometer

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.

Both are free to download. Barometric Pressure sells 3 one-off in-app purchases and Professional Barometer sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

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. Written reviews complicate that: 61% of Barometric Pressure's written reviews are positive against 45% of Professional Barometer's, so the app with the better star average is not the one people write more warmly about.

Barometric Pressure ships an update every 5 days, Professional Barometer every 42 months. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
