Verdict
The clearest difference is review sentiment: PDF OCR at 100% against Stacked's 67%. PDF OCR also leads on update cadence (every 3 weeks vs every 7 months) and monetization model (free vs free with in-app purchases). Stacked's advantage is rating (4.6 vs 4.4). On price, ratings volume, ads 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
Both are free to download. PDF OCR sells 3 in-app purchases, starting at $3.99 per month and Stacked sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
Stacked holds the better App Store score, 4.6 against 4.4. Both are backed by a comparable volume of ratings — 7 and 13 respectively. Written reviews complicate that: 100% of PDF OCR's written reviews are positive against 67% of Stacked's, so the app with the better star average is not the one people write more warmly about.
PDF OCR ships an update every 3 weeks, Stacked every 7 months. The most recent releases landed on November 2, 2026 and October 24, 2026 respectively.
