# U vs JD Memory

The clearest difference is rating: JD Memory at 2.7 against U's 2.3. JD Memory also leads on iOS requirement (9.0 vs 12.1). U's advantage is review sentiment (29% vs 18%). On price, ratings volume, update cadence and ads there is nothing between them.

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

JD Memory holds the better App Store score, 2.7 against 2.3. Both are backed by a comparable volume of ratings — 17 and 32 respectively. Written reviews complicate that: 29% of U's written reviews are positive against 18% of JD Memory'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 3 months. The most recent releases landed on October 8, 2026 and October 9, 2026 respectively.
