# OneBook vs Sonelune

The clearest difference is update cadence: Sonelune at every 3 days against OneBook's weekly. OneBook's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. OneBook sells 2 in-app purchases, starting at $8.00 per month and Sonelune sells 4 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.

OneBook ships an update weekly, Sonelune every 3 days. The most recent releases landed on November 6, 2026 and October 31, 2026 respectively.
