# Sylvi vs Flashcard Blocker

The clearest difference is ratings volume: Sylvi at 342 against Flashcard Blocker's 4. Sylvi also leads on update cadence (every 3 days vs weekly) and iOS requirement (16.4 vs 18.0). Flashcard Blocker's advantage is rating (5.0 vs 4.7) and review sentiment (100% vs 83%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Sylvi sells 10 in-app purchases, starting at $2.99 per month and Flashcard Blocker sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Flashcard Blocker holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Sylvi has 342 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 83% of Sylvi's written reviews are positive against 100% of Flashcard Blocker's.

Sylvi ships an update every 3 days, Flashcard Blocker weekly. The most recent releases landed on November 4, 2026 and November 5, 2026 respectively.
