Verdict

The call

The clearest difference is monetization model: Polaris Office at free with in-app purchases against PDF Pro's subscription. Polaris Office also leads on update cadence (every 4 weeks vs every 2 months). PDF Pro's advantage is ads (none vs shown) and rating (4.7 vs 4.4). On price, review sentiment, ratings volume and in-app purchases there is nothing between them.

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. PDF Pro sells 12 in-app purchases, starting at $1.99 per month and Polaris Office sells 13 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

PDF Pro holds the better App Store score, 4.7 against 4.4. Both are backed by a comparable volume of ratings — 6.9K and 2.5K respectively. Written reviews complicate that: 60% of PDF Pro's written reviews are positive against 63% of Polaris Office's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

PDF Pro ships an update every 2 months, Polaris Office every 4 weeks. The most recent releases landed on October 14, 2026 and October 15, 2026 respectively.
