Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
waterdrop® Hydration App holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: waterdrop® Hydration App has 770 ratings behind it against 65, so its average is the more settled of the two. Written reviews complicate that: 88% of H2O's written reviews are positive against 83% of waterdrop® Hydration App's, so the app with the better star average is not the one people write more warmly about.
H2O ships an update every 4 months, waterdrop® Hydration App every 2 months. The most recent releases landed on September 23, 2026 and September 24, 2026 respectively.
