# Water Tracker! vs H2O

The clearest difference is ratings volume: H2O at 175 against Water Tracker!'s 3. Water Tracker!'s advantage is review sentiment (100% vs 85%) and iOS requirement (9.3 vs 26.0). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Water Tracker! sells 1 one-off in-app purchase and H2O sells 4 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

H2O holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: H2O has 175 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 100% of Water Tracker!'s written reviews are positive against 85% of H2O's, so the app with the better star average is not the one people write more warmly about.

Water Tracker! ships an update every 5 days, H2O every 3 days. The most recent releases landed on October 12, 2026 and November 1, 2026 respectively.
