Verdict

The call

The clearest difference is ads: WaterUnicorns at none against Hydration Tracker's shown. WaterUnicorns also leads on update cadence (daily vs every 9 days) and review sentiment (100% vs 88%). Hydration Tracker's advantage is rating (4.8 vs 4.5) and ratings volume (26 vs 4). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. WaterUnicorns sells 8 in-app purchases, starting at $1.99 per month and Hydration Tracker sells 5 in-app purchases, starting at $1.49 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Hydration Tracker holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Hydration Tracker has 26 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 100% of WaterUnicorns's written reviews are positive against 88% of Hydration Tracker's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

WaterUnicorns ships an update daily, Hydration Tracker every 9 days. Both last shipped on October 30, 2026.
