Verdict

ReceptionRating · Positive reviews · Number of ratings

Secret Diary holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Secure Notepad Pro has 2.7K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 76% of Secure Notepad Pro's written reviews are positive against 70% of Secret Diary's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Secure Notepad Pro ships an update every 5 months, Secret Diary every 3 months. The most recent releases landed on September 23, 2026 and August 23, 2026 respectively.
