# Professional Barometer vs Barometer

The clearest difference is update cadence: Barometer at every 5 months against Professional Barometer's every 42 months. Barometer also leads on ratings volume (70 vs 17). Professional Barometer's advantage is monetization model (ad-supported vs free with in-app purchases) and review sentiment (45% vs 35%). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Professional Barometer sells 3 in-app purchases, starting at $1.99 per month and Barometer sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Barometer holds the better App Store score, 4.3 against 4.2. Both are backed by a comparable volume of ratings — 17 and 70 respectively. Written reviews complicate that: 45% of Professional Barometer's written reviews are positive against 35% of Barometer's, so the app with the better star average is not the one people write more warmly about.

Professional Barometer ships an update every 42 months, Barometer every 5 months. Both last shipped on November 7, 2026.
