Verdict
The clearest difference is ads: H2O at none against Water Reminder's shown. H2O also leads on update cadence (every 3 days vs every 3 weeks) and monetization model (free vs free with in-app purchases). Water Reminder's advantage is rating (5.0 vs 4.5) and iOS requirement (17.0 vs 26.0). On price, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. H2O sells 4 in-app purchases, starting at $1.99 per month and Water Reminder sells 3 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.
Water Reminder holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: H2O has 175 ratings behind it against 8, so its average is the more settled of the two.
H2O ships an update every 3 days, Water Reminder every 3 weeks. The most recent releases landed on November 2, 2026 and November 5, 2026 respectively.
