Verdict

The call

The clearest difference is rating: Memory King at 4.4 against KoolPuzz's 3.0. Memory King also leads on ads (none vs shown) and ratings volume (332 vs 1). KoolPuzz's advantage is update cadence (every 9 days vs every 3 months) and review sentiment (100% vs 91%). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Memory King sells 3 one-off in-app purchases and KoolPuzz sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Memory King holds the better App Store score, 4.4 against 3.0. That said, the two scores are not equally well evidenced: Memory King has 332 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 91% of Memory King's written reviews are positive against 100% of KoolPuzz's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Memory King ships an update every 3 months, KoolPuzz every 9 days. Both last shipped on November 1, 2026.
