# SeaDrive vs Ditch

The clearest difference is rating: SeaDrive at 4.5 against Ditch's 3.9. SeaDrive also leads on review sentiment (89% vs 64%) and ratings volume (248 vs 22). Ditch's advantage is chart position (#189 vs unranked) and iOS requirement (15.1 vs 18.1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. SeaDrive sells 3 in-app purchases, starting at $2.99 per month and Ditch sells 2 in-app purchases, starting at $24.99 per year. Whichever you choose, the download price is not the number that matters.

SeaDrive holds the better App Store score, 4.5 against 3.9. That said, the two scores are not equally well evidenced: SeaDrive has 248 ratings behind it against 22, so its average is the more settled of the two. Written reviews point the same way: 89% of SeaDrive's written reviews are positive against 64% of Ditch's.

SeaDrive ships an update fortnightly, Ditch monthly. The most recent releases landed on September 25, 2026 and August 4, 2026 respectively.
