ReceptionRating · Positive reviews · Number of ratings

Piko's Blocks holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: On the line has 140 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 78% of On the line's written reviews are positive against 75% of Piko's Blocks's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

On the line ships an update every 4 months, Piko's Blocks monthly. The most recent releases landed on October 26, 2026 and October 29, 2026 respectively.
