# DONIA vs Smart Waters

The clearest difference is review sentiment: DONIA at 63% against Smart Waters's 25%. DONIA also leads on ratings volume (34 vs 1). Smart Waters's advantage is rating (5.0 vs 4.5) and in-app purchases (none vs 2). On price, ads, device support and iOS requirement there is nothing between them.

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.
