# SailFlow vs SailDay

The clearest difference is ads: SailFlow at none against SailDay's shown. SailFlow also leads on chart position (#41 vs unranked). SailDay's advantage is update cadence (every 3 days vs every 3 weeks) and iOS requirement (13.0 vs 15.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. SailFlow sells 10 in-app purchases, starting at $3.99 per month and SailDay sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

SailFlow ships an update every 3 weeks, SailDay every 3 days. The most recent releases landed on October 22, 2026 and October 5, 2026 respectively.
