# SoilIQ vs WatchBarometer

The clearest difference is update cadence: SoilIQ at every 4 days against WatchBarometer's every 3 months. SoilIQ also leads on ratings volume (22 vs 1) and iOS requirement (17.6 vs 26.0). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. SoilIQ sells 2 in-app purchases, starting at $4.99 per month and WatchBarometer sells 1 in-app purchase, starting at $3.99 per year. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for SoilIQ against 5.0 for WatchBarometer. That said, the two scores are not equally well evidenced: SoilIQ has 22 ratings behind it against 1, so its average is the more settled of the two.

SoilIQ ships an update every 4 days, WatchBarometer every 3 months. The most recent releases landed on October 24, 2026 and October 31, 2026 respectively.
