# Chinese Calendar vs PDF Reader

The clearest difference is rating: PDF Reader at 4.7 against Chinese Calendar's 2.0. PDF Reader also leads on review sentiment (37% vs 0%) and update cadence (every 8 days vs every 2 months). Chinese Calendar's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Chinese Calendar sells 1 one-off in-app purchase and PDF Reader sells 9 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

PDF Reader holds the better App Store score, 4.7 against 2.0. That said, the two scores are not equally well evidenced: PDF Reader has 753 ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 0% of Chinese Calendar's written reviews are positive against 37% of PDF Reader's.

Chinese Calendar ships an update every 2 months, PDF Reader every 8 days. The most recent releases landed on October 20, 2026 and October 30, 2026 respectively.
