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. DONIA sells 2 in-app purchases, starting at $2.49 per month. Smart Waters asks for nothing beyond the download.
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.
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.
