Verdict
The clearest difference is rating: Memento at 5.0 against NuKey's 4.4. Memento also leads on review sentiment (100% vs 62%). NuKey's advantage is update cadence (every 2 days vs fortnightly) and ratings volume (50 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Memento sells 1 one-off in-app purchase and NuKey sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Memento holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: NuKey has 50 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 100% of Memento's written reviews are positive against 62% of NuKey's.
Memento ships an update fortnightly, NuKey every 2 days. The most recent releases landed on October 31, 2026 and November 1, 2026 respectively.
