Verdict

The call

The clearest difference is price: 9 Kings at Free against Memory's $8.99. 9 Kings also leads on ratings volume (927 vs 12) and rating (4.8 vs 4.6). Memory's advantage is in-app purchases (none vs 1) and review sentiment (90% vs 64%). On update cadence, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

9 Kings holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: 9 Kings has 927 ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 90% of Memory's written reviews are positive against 64% of 9 Kings's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Memory ships an update every 10 days, 9 Kings weekly. The most recent releases landed on November 1, 2026 and October 31, 2026 respectively.
