# Pool Filter Pro CirrusSense vs Alеrtly

Pool Filter Pro CirrusSense and Alеrtly both sit at 4.0 stars, but that hides the real split: 50% of Pool Filter Pro CirrusSense's written reviews are positive against 9% of Alеrtly's. Pool Filter Pro CirrusSense also leads on in-app purchases (none vs 3) and update cadence (every 3 weeks vs every 4 months). Alеrtly's advantage is ratings volume (82 vs 3). On price, rating, ads and device support there is nothing between them.

Both are free to download. Alеrtly sells 3 in-app purchases, starting at $5.99 per 7 days. Pool Filter Pro CirrusSense asks for nothing beyond the download.

Alеrtly holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: Alеrtly has 82 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 50% of Pool Filter Pro CirrusSense's written reviews are positive against 9% of Alеrtly's, so the app with the better star average is not the one people write more warmly about.

Pool Filter Pro CirrusSense ships an update every 3 weeks, Alеrtly every 4 months. The most recent releases landed on October 24, 2026 and October 22, 2026 respectively.
