# SailFlow vs PredictCurrent

The clearest difference is review sentiment: SailFlow at 84% against PredictCurrent's 57%. SailFlow also leads on ratings volume (5.7K vs 255) and rating (4.7 vs 4.5). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. SailFlow sells 10 in-app purchases, starting at $3.99 per month and PredictCurrent sells 5 in-app purchases, starting at $15.00 per month. Whichever you choose, the download price is not the number that matters.

SailFlow holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: SailFlow has 5.7K ratings behind it against 255, so its average is the more settled of the two. Written reviews point the same way: 84% of SailFlow's written reviews are positive against 57% of PredictCurrent's.

SailFlow ships an update every 3 weeks, PredictCurrent monthly. The most recent releases landed on September 25, 2026 and September 23, 2026 respectively.
