# LM NoteBook PRO vs Deepen

The clearest difference is rating: Deepen at 5.0 against LM NoteBook PRO's 3.1. Deepen also leads on update cadence (every 5 days vs every 5 weeks). LM NoteBook PRO's advantage is ratings volume (15 vs 1). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. LM NoteBook PRO sells 5 in-app purchases, starting at $0.99 per 7 days and Deepen sells 3 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Deepen holds the better App Store score, 5.0 against 3.1. That said, the two scores are not equally well evidenced: LM NoteBook PRO has 15 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.

LM NoteBook PRO ships an update every 5 weeks, Deepen every 5 days. The most recent releases landed on October 25, 2026 and October 23, 2026 respectively.
