ReceptionRating · Positive reviews · Number of ratings

Ballpins holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: 21 Letters has 64 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 82% of 21 Letters's written reviews are positive against 0% of Ballpins's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 2 days. The most recent releases landed on November 4, 2026 and October 30, 2026 respectively.
