# WeatherPro vs Cyanometer

The clearest difference is rating: WeatherPro at 4.7 against Cyanometer's 2.8. WeatherPro also leads on review sentiment (59% vs 25%) and update cadence (every 3 months vs every 39 months). Cyanometer's advantage is in-app purchases (none vs 5). On price, ads, chart position and device support there is nothing between them.

WeatherPro costs $0.99 and Cyanometer $0.99 up front. WeatherPro sells 4 in-app purchases, starting at $0.99 per month. Cyanometer asks for nothing beyond the download.

WeatherPro holds the better App Store score, 4.7 against 2.8. That said, the two scores are not equally well evidenced: WeatherPro has 3.8K ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 59% of WeatherPro's written reviews are positive against 25% of Cyanometer's.

WeatherPro ships an update every 3 months, Cyanometer every 39 months. The most recent releases landed on September 24, 2026 and September 22, 2026 respectively.
