Verdict
The clearest difference is rating: C at 4.5 against Raymarine's 1.5. C also leads on review sentiment (51% vs 12%) and ratings volume (2.3K vs 17). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. C sells 10 in-app purchases, starting at $1.99 per month and Raymarine sells 6 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.
C holds the better App Store score, 4.5 against 1.5. That said, the two scores are not equally well evidenced: C has 2.3K ratings behind it against 17, so its average is the more settled of the two. Written reviews point the same way: 51% of C's written reviews are positive against 12% of Raymarine's.
C ships an update every 6 weeks, Raymarine every 4 months. The most recent releases landed on September 23, 2026 and September 21, 2026 respectively.
