# SailFlow vs DawnTracker

The clearest difference is price: SailFlow at Free against DawnTracker's $2.99. SailFlow also leads on ratings volume (5.8K vs 1) and chart position (#40 vs unranked). DawnTracker's advantage is in-app purchases (none vs 10) and update cadence (every 3 days vs every 3 weeks). On ads there is nothing between them.

SailFlow is free to download; DawnTracker costs $2.99 up front. SailFlow sells 10 in-app purchases, starting at $3.99 per month. DawnTracker asks for nothing beyond the download.

DawnTracker holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: SailFlow has 5.8K ratings behind it against 1, so its average is the more settled of the two.

SailFlow ships an update every 3 weeks, DawnTracker every 3 days. The most recent releases landed on October 14, 2026 and October 12, 2026 respectively.
