# Fast OCR vs PDF Master

The clearest difference is monetization model: Fast OCR at free with in-app purchases against PDF Master's subscription. Fast OCR also leads on ads (none vs shown) and update cadence (every 2 days vs every 2 weeks). PDF Master's advantage is ratings volume (202 vs 1) and rating (4.3 vs 4.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Fast OCR sells 2 in-app purchases, starting at $5.99 per month and PDF Master sells 10 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

PDF Master holds the better App Store score, 4.3 against 4.0. That said, the two scores are not equally well evidenced: PDF Master has 202 ratings behind it against 1, so its average is the more settled of the two.

Fast OCR ships an update every 2 days, PDF Master every 2 weeks. Both last shipped on November 4, 2026.
