# PRO CHARTS vs SeaDrive

PRO CHARTS and SeaDrive both sit at 4.5 stars, but that hides the real split: 89% of SeaDrive's written reviews are positive against 27% of PRO CHARTS's. SeaDrive also leads on update cadence (fortnightly vs every 2 months). PRO CHARTS's advantage is ratings volume (8.5K vs 263) and chart position (#194 vs unranked). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. PRO CHARTS sells 4 in-app purchases, starting at $2.99 per month and SeaDrive sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.5 for PRO CHARTS against 4.5 for SeaDrive. That said, the two scores are not equally well evidenced: PRO CHARTS has 8.5K ratings behind it against 263, so its average is the more settled of the two. Written reviews are what separate them: 27% of PRO CHARTS's written reviews are positive against 89% of SeaDrive's.

PRO CHARTS ships an update every 2 months, SeaDrive fortnightly. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
