# InstaScan vs PDF Summarizer

The clearest difference is monetization model: InstaScan at free with in-app purchases against PDF Summarizer's subscription. InstaScan also leads on review sentiment (60% vs 33%) and ratings volume (1.9K vs 16). PDF Summarizer's advantage is ads (none vs shown). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. InstaScan sells 3 in-app purchases, starting at $7.99 per 3 months and PDF Summarizer sells 8 in-app purchases, starting at $5.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.6 for InstaScan against 4.6 for PDF Summarizer. That said, the two scores are not equally well evidenced: InstaScan has 1.9K ratings behind it against 16, so its average is the more settled of the two. Written reviews are what separate them: 60% of InstaScan's written reviews are positive against 33% of PDF Summarizer's.
