# SankeyMaster vs Flow Nodes

The clearest difference is price: Flow Nodes at Free against SankeyMaster's $19.99. Flow Nodes also leads on review sentiment (78% vs 50%) and update cadence (every 2 weeks vs every 5 weeks). SankeyMaster's advantage is rating (5.0 vs 4.4) and in-app purchases (none vs 3). On ads and device support there is nothing between them.

Flow Nodes is free to download; SankeyMaster costs $19.99 up front. Flow Nodes sells 3 in-app purchases, starting at $2.99 per month. SankeyMaster asks for nothing beyond the download.

SankeyMaster holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Flow Nodes has 9 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of SankeyMaster's written reviews are positive against 78% of Flow Nodes's, so the app with the better star average is not the one people write more warmly about.

SankeyMaster ships an update every 5 weeks, Flow Nodes every 2 weeks. Both last shipped on November 4, 2026.
