# Seapilot vs C

The clearest difference is rating: C at 4.5 against Seapilot's 2.9. C also leads on ratings volume (2.3K vs 15) and review sentiment (51% vs 38%). Seapilot's advantage is iOS requirement (9.3 vs 15.1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Seapilot sells 18 in-app purchases, starting at $8.99 per year and C sells 10 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

C holds the better App Store score, 4.5 against 2.9. That said, the two scores are not equally well evidenced: C has 2.3K ratings behind it against 15, so its average is the more settled of the two. Written reviews point the same way: 38% of Seapilot's written reviews are positive against 51% of C's.

Seapilot ships an update every 3 months, C every 6 weeks. The most recent releases landed on September 30, 2026 and October 13, 2026 respectively.
