Verdict

The call

The clearest difference is review sentiment: Plain Flashcards at 73% against AlgoApp's 50%. AlgoApp's advantage is ratings volume (20K vs 314) and rating (4.7 vs 4.4). On price, update cadence, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

AlgoApp holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: AlgoApp has 20K ratings behind it against 314, so its average is the more settled of the two. Written reviews complicate that: 50% of AlgoApp's written reviews are positive against 73% of Plain Flashcards's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

AlgoApp ships an update every 4 days, Plain Flashcards weekly. The most recent releases landed on October 31, 2026 and October 29, 2026 respectively.
