Verdict
The clearest difference is rating: Flashcards by NKO at 4.9 against Interpretrain's 4.4. Flashcards by NKO also leads on ratings volume (2K vs 11) and update cadence (every 4 weeks vs every 2 months). Interpretrain's advantage is in-app purchases (none vs 13) and iOS requirement (13.0 vs 17). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. Flashcards by NKO sells 13 in-app purchases, starting at $1.99 per month. Interpretrain asks for nothing beyond the download.
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.
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.
