ReceptionRating · Positive reviews · Number of ratings

Pepp holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: iSequence HD has 33 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 77% of iSequence HD's written reviews are positive against 29% of Pepp's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

iSequence HD ships an update every 3 months, Pepp every 6 months. The most recent releases landed on October 14, 2026 and October 5, 2026 respectively.
