# Flume Water vs LeanMD

The clearest difference is in-app purchases: LeanMD at none against Flume Water's 2. LeanMD also leads on update cadence (every 3 weeks vs every 6 weeks) and review sentiment (67% vs 59%). Flume Water's advantage is rating (4.7 vs 4.2) and ratings volume (1.7K vs 11). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Flume Water sells 2 in-app purchases, starting at $49.99 per year. LeanMD asks for nothing beyond the download.

Flume Water holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: Flume Water has 1.7K ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 59% of Flume Water's written reviews are positive against 67% of LeanMD's, so the app with the better star average is not the one people write more warmly about.

Flume Water ships an update every 6 weeks, LeanMD every 3 weeks. The most recent releases landed on October 23, 2026 and October 22, 2026 respectively.
