Spirogenix MoldWave™'s advantage is review sentiment (67% vs 26%) and update cadence (weekly vs every 3 weeks). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Spirogenix MoldWave™ sells 6 in-app purchases, starting at $9.99 per 7 days. Blueair asks for nothing beyond the download.

Blueair holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: Blueair has 24K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 26% of Blueair's written reviews are positive against 67% of Spirogenix MoldWave™'s, so the app with the better star average is not the one people write more warmly about.

Blueair ships an update every 3 weeks, Spirogenix MoldWave™ weekly. The most recent releases landed on November 4, 2026 and October 30, 2026 respectively.
