# SailFlow vs Squid

SailFlow and Squid both sit at 4.7 stars, but that hides the real split: 84% of SailFlow's written reviews are positive against 38% of Squid's. SailFlow also leads on ratings volume (5.8K vs 55) and chart position (#41 vs unranked). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. SailFlow sells 10 in-app purchases, starting at $3.99 per month and Squid sells 8 in-app purchases, starting at $5.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for SailFlow against 4.8 for Squid. That said, the two scores are not equally well evidenced: SailFlow has 5.8K ratings behind it against 55, so its average is the more settled of the two. Written reviews are what separate them: 84% of SailFlow's written reviews are positive against 38% of Squid's.

SailFlow ships an update every 3 weeks, Squid monthly. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
