ReceptionRating · Positive reviews · Number of ratings

Smart Waters holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: DONIA has 34 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 63% of DONIA's written reviews are positive against 25% of Smart Waters's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

DONIA ships an update every 4 weeks, Smart Waters every 10 days. The most recent releases landed on October 18, 2026 and October 9, 2026 respectively.
