# ARNBOOK vs SparkJoy

The clearest difference is update cadence: SparkJoy at every 2 days against ARNBOOK's every 3 weeks. ARNBOOK's advantage is ratings volume (5 vs 1). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. ARNBOOK sells 17 one-off in-app purchases and SparkJoy sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ARNBOOK holds the better App Store score, 1.2 against 1.0. That said, the two scores are not equally well evidenced: ARNBOOK has 5 ratings behind it against 1, so its average is the more settled of the two.

ARNBOOK ships an update every 3 weeks, SparkJoy every 2 days. The most recent releases landed on September 23, 2026 and September 19, 2026 respectively.
