# PDF OCR vs SpongeHome

The clearest difference is rating: SpongeHome at 5.0 against PDF OCR's 4.4. SpongeHome also leads on update cadence (weekly vs every 3 weeks). PDF OCR's advantage is monetization model (free vs freemium) and ratings volume (7 vs 1). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. PDF OCR sells 3 in-app purchases, starting at $3.99 per month and SpongeHome sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

SpongeHome holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: PDF OCR has 7 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

PDF OCR ships an update every 3 weeks, SpongeHome weekly. The most recent releases landed on October 25, 2026 and October 18, 2026 respectively.
