Plan your time on the lake with helpful tools for weather radar, lake levels, bathymetry on supported lakes, marinas, fuel reports, day planning, and Fishing Intelligence.

Verdict
The clearest difference is review sentiment: BuoyPilot at 100% against C's 51%. BuoyPilot also leads on rating (5.0 vs 4.5) and update cadence (fortnightly vs every 6 weeks). C's advantage is ratings volume (2.3K vs 4) and chart position (#92 vs unranked). 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 BuoyPilot sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
BuoyPilot holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: C has 2.3K ratings behind it against 4, 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 100% of BuoyPilot's.
C ships an update every 6 weeks, BuoyPilot fortnightly. The most recent releases landed on October 15, 2026 and September 18, 2026 respectively.
