The call

The clearest difference is rating: Diary With Password at 4.7 against BiiB's 3.0. Diary With Password also leads on ratings volume (27K vs 2).

ReceptionRating · Positive reviews · Number of ratings

Diary With Password holds the better App Store score, 4.7 against 3.0. That said, the two scores are not equally well evidenced: Diary With Password has 27K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 92% of Diary With Password's written reviews are positive against 100% of BiiB's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Diary With Password ships an update every 2 weeks, BiiB weekly. The most recent releases landed on November 8, 2026 and October 30, 2026 respectively.
