CostPrice · In-app purchases · Ads · Monetization

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
