# WaterGuru vs iopool

The clearest difference is ads: WaterGuru at none against iopool's shown. WaterGuru also leads on review sentiment (74% vs 60%) and monetization model (free vs ad-supported). iopool's advantage is rating (4.3 vs 4.1). On price, ratings volume, update cadence and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

iopool holds the better App Store score, 4.3 against 4.1. Both are backed by a comparable volume of ratings — 239 and 95 respectively. Written reviews complicate that: 74% of WaterGuru's written reviews are positive against 60% of iopool's, so the app with the better star average is not the one people write more warmly about.

WaterGuru ships an update every 4 weeks, iopool every 2 weeks. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
