# PDF Reader vs WPS Office

The clearest difference is review sentiment: WPS Office at 82% against PDF Reader's 33%. WPS Office also leads on rating (4.8 vs 3.5) and update cadence (fortnightly vs every 9 months). PDF Reader's advantage is monetization model (free with in-app purchases vs subscription) and iOS requirement (9.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. PDF Reader sells 1 one-off in-app purchase and WPS Office sells 23 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

WPS Office holds the better App Store score, 4.8 against 3.5. That said, the two scores are not equally well evidenced: WPS Office has 18K ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 33% of PDF Reader's written reviews are positive against 82% of WPS Office's.

PDF Reader ships an update every 9 months, WPS Office fortnightly. The most recent releases landed on September 14, 2026 and September 24, 2026 respectively.
