# PDF Reader vs HTML5教程

The clearest difference is ads: PDF Reader at none against HTML5教程's shown. PDF Reader also leads on update cadence (every 3 weeks vs every 4 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. PDF Reader sells 5 one-off in-app purchases and HTML5教程 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

PDF Reader ships an update every 3 weeks, HTML5教程 every 4 months. The most recent releases landed on September 25, 2026 and May 18, 2026 respectively.
