Verdict

The call

The clearest difference is monetization model: Water Tracker at free with in-app purchases against Hydro Coach's subscription. Water Tracker also leads on review sentiment (100% vs 65%) and update cadence (every 3 days vs monthly). Hydro Coach's advantage is rating (4.7 vs 4.3) and ratings volume (985 vs 6). On price, ads, in-app purchases and device support there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Hydro Coach sells 8 in-app purchases, starting at $2.99 per month and Water Tracker sells 4 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Hydro Coach holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Hydro Coach has 985 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 65% of Hydro Coach's written reviews are positive against 100% of Water Tracker's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Hydro Coach ships an update monthly, Water Tracker every 3 days. The most recent releases landed on November 3, 2026 and November 5, 2026 respectively.
