Verdict
The clearest difference is ratings volume: PDF Expert at 216K against Rest Assured's 2. PDF Expert also leads on chart position (#76 vs unranked) and iOS requirement (16.0 vs 18.0). Rest Assured's advantage is rating (5.0 vs 4.7). On price, ads, in-app purchases and monetization model 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
Both are free to download. PDF Expert sells 10 in-app purchases, starting at $9.99 per month and Rest Assured sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
Rest Assured holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: PDF Expert has 216K ratings behind it against 2, so its average is the more settled of the two.
