# Barometer Plus vs Professional Barometer

The clearest difference is in-app purchases: Professional Barometer at none against Barometer Plus's 4. Professional Barometer also leads on rating (4.3 vs 4.0) and iOS requirement (9.0 vs 13.0). Barometer Plus's advantage is update cadence (every 6 weeks vs every 16 months) and ratings volume (409 vs 13). On price, ads and device support there is nothing between them.

Both are free to download. Barometer Plus sells 4 one-off in-app purchases. Professional Barometer asks for nothing beyond the download.

Professional Barometer holds the better App Store score, 4.3 against 4.0. That said, the two scores are not equally well evidenced: Barometer Plus has 409 ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 64% of Barometer Plus'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.

Barometer Plus ships an update every 6 weeks, Professional Barometer every 16 months. The most recent releases landed on September 29, 2026 and September 25, 2026 respectively.
