# Pool Measure Pro vs Pool Chem Calculator

The clearest difference is ads: Pool Measure Pro at none against Pool Chem Calculator's shown. Pool Measure Pro also leads on review sentiment (70% vs 36%) and iOS requirement (13.0 vs 16.6). Pool Chem Calculator's advantage is update cadence (weekly vs every 3 months) and rating (4.4 vs 4.1). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Pool Measure Pro sells 7 one-off in-app purchases and Pool Chem Calculator sells 1 in-app purchase, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Pool Chem Calculator holds the better App Store score, 4.4 against 4.1. Both are backed by a comparable volume of ratings — 10 and 42 respectively. Written reviews complicate that: 70% of Pool Measure Pro's written reviews are positive against 36% of Pool Chem Calculator's, so the app with the better star average is not the one people write more warmly about.

Pool Measure Pro ships an update every 3 months, Pool Chem Calculator weekly. The most recent releases landed on November 6, 2026 and November 2, 2026 respectively.
