# cards.study vs Spark

The clearest difference is ads: cards.study at none against Spark's shown. cards.study also leads on rating (5.0 vs 4.8). Spark's advantage is ratings volume (2.8K vs 8) and update cadence (weekly vs every 4 weeks). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. cards.study sells 1 in-app purchase, starting at $5.99 per month and Spark sells 7 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

cards.study holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Spark has 2.8K ratings behind it against 8, so its average is the more settled of the two. Written reviews point the same way: 100% of cards.study's written reviews are positive against 93% of Spark's.

cards.study ships an update every 4 weeks, Spark weekly. The most recent releases landed on November 4, 2026 and November 9, 2026 respectively.
