# Pool vs Clorox Pool

The clearest difference is price: Clorox Pool at Free against Pool's $4.99. Clorox Pool also leads on rating (4.6 vs 4.2) and ratings volume (29K vs 629). Pool's advantage is ads (none vs shown). On review sentiment, update cadence, in-app purchases and device support there is nothing between them.

Clorox Pool is free to download; Pool costs $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Clorox Pool holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: Clorox Pool has 29K ratings behind it against 629, so its average is the more settled of the two. Written reviews complicate that: 22% of Pool's written reviews are positive against 14% of Clorox Pool's, so the app with the better star average is not the one people write more warmly about.

Pool ships an update every 5 weeks, Clorox Pool every 2 months. The most recent releases landed on September 23, 2026 and September 26, 2026 respectively.
