# Summarify vs LM NoteBook PRO

The clearest difference is rating: Summarify at 4.7 against LM NoteBook PRO's 3.5. Summarify also leads on ratings volume (439 vs 20). LM NoteBook PRO's advantage is review sentiment (100% vs 84%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Summarify sells 2 in-app purchases, starting at $4.99 per month and LM NoteBook PRO sells 5 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Summarify holds the better App Store score, 4.7 against 3.5. That said, the two scores are not equally well evidenced: Summarify has 439 ratings behind it against 20, so its average is the more settled of the two. Written reviews complicate that: 84% of Summarify's written reviews are positive against 100% of LM NoteBook PRO's, so the app with the better star average is not the one people write more warmly about.

Summarify ships an update monthly, LM NoteBook PRO every 5 weeks. The most recent releases landed on November 3, 2026 and November 4, 2026 respectively.
