# SailFlow vs SailWindow

The clearest difference is price: SailFlow at Free against SailWindow's $0.99. SailFlow also leads on ratings volume (5.9K vs 2) and chart position (#43 vs unranked). SailWindow's advantage is in-app purchases (none vs 10) and update cadence (every 6 days vs every 3 weeks). On ads there is nothing between them.

SailFlow is free to download; SailWindow costs $0.99 up front. SailFlow sells 10 in-app purchases, starting at $3.99 per month. SailWindow asks for nothing beyond the download.

SailWindow holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: SailFlow has 5.9K ratings behind it against 2, so its average is the more settled of the two.

SailFlow ships an update every 3 weeks, SailWindow every 6 days. The most recent releases landed on November 1, 2026 and October 31, 2026 respectively.
