# MyDolphin Plus vs U

The clearest difference is rating: MyDolphin Plus at 4.7 against U's 3.0. MyDolphin Plus also leads on ratings volume (8.9K vs 1). U's advantage is review sentiment (50% vs 20%) and iOS requirement (10.0 vs 13.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

MyDolphin Plus holds the better App Store score, 4.7 against 3.0. That said, the two scores are not equally well evidenced: MyDolphin Plus has 8.9K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 20% of MyDolphin Plus's written reviews are positive against 50% of U's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on September 26, 2026 and June 1, 2026 respectively.
