ReceptionRating · Positive reviews · Number of ratings

ROAST APP holds the better App Store score, 4.9 against 3.9. That said, the two scores are not equally well evidenced: ROAST APP has 794 ratings behind it against 54, so its average is the more settled of the two. Written reviews complicate that: 53% of FOUR's written reviews are positive against 52% of ROAST APP's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

FOUR ships an update monthly, ROAST APP every 6 weeks. The most recent releases landed on October 30, 2026 and October 21, 2026 respectively.
