# SeaNav vs SeaDrive

SeaNav and SeaDrive both sit at 4.4 stars, but that hides the real split: 89% of SeaDrive's written reviews are positive against 55% of SeaNav's. SeaNav's advantage is device support (4 vs 2) and iOS requirement (15.6 vs 18.1). On price, rating, ratings volume and update cadence there is nothing between them.

Both are free to download. SeaNav sells 18 in-app purchases, starting at $4.99 per year 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 — 4.4 for SeaNav against 4.5 for SeaDrive. Both are backed by a comparable volume of ratings — 247 and 248 respectively. Written reviews are what separate them: 55% of SeaNav's written reviews are positive against 89% of SeaDrive's.

SeaNav ships an update every 3 weeks, SeaDrive fortnightly. The most recent releases landed on September 22, 2026 and September 25, 2026 respectively.
