# abcNotes vs pdf

The clearest difference is rating: abcNotes at 4.6 against pdf's 4.0. abcNotes also leads on review sentiment (77% vs 49%) and ratings volume (2.9K vs 17). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. abcNotes sells 1 one-off in-app purchase and pdf sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

abcNotes holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: abcNotes has 2.9K ratings behind it against 17, so its average is the more settled of the two. Written reviews point the same way: 77% of abcNotes's written reviews are positive against 49% of pdf's.

abcNotes ships an update every 2 weeks, pdf every 5 weeks. The most recent releases landed on September 29, 2026 and July 10, 2026 respectively.
