ReceptionRating · Positive reviews · Number of ratings

Nonogram.com holds the better App Store score, 4.6 against 3.2. That said, the two scores are not equally well evidenced: Nonogram.com has 195K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 56% of iSometric 3D Form's written reviews are positive against 47% of Nonogram.com's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

iSometric 3D Form ships an update monthly, Nonogram.com every 5 weeks. The most recent releases landed on October 15, 2026 and October 18, 2026 respectively.
