ReceptionRating · Positive reviews · Number of ratings

Flashcards by NKO holds the better App Store score, 4.9 against 4.4. That said, the two scores are not equally well evidenced: Flashcards by NKO has 2K ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 94% of Flashcards by NKO's written reviews are positive against 100% of Interpretrain's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Flashcards by NKO ships an update every 4 weeks, Interpretrain every 2 months. The most recent releases landed on September 22, 2026 and June 3, 2026 respectively.
