Verdict

The call

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.
