# 百度文库 vs 数独天天练

The clearest difference is ads: 数独天天练 at none against 百度文库's shown. 百度文库's advantage is update cadence (every 2 weeks vs every 28 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. 百度文库 sells 17 in-app purchases, starting at $1.99 per month and 数独天天练 sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

百度文库 ships an update every 2 weeks, 数独天天练 every 28 months. The most recent releases landed on October 28, 2026 and October 27, 2026 respectively.
