Verdict

The call

The clearest difference is rating: Breathe Bubbles at 5.0 against Water Tracker's 4.5. Water Tracker's advantage is update cadence (every 3 days vs weekly) and review sentiment (100% vs 90%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Breathe Bubbles sells 9 in-app purchases, starting at $9.99 per month and Water Tracker sells 5 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Breathe Bubbles holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Water Tracker has 16 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 90% of Breathe Bubbles'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

Breathe Bubbles ships an update weekly, Water Tracker every 3 days. The most recent releases landed on November 2, 2026 and October 28, 2026 respectively.
