# iSometric 3D Form vs Nonogram.com

The clearest difference is rating: Nonogram.com at 4.6 against iSometric 3D Form's 3.2. Nonogram.com also leads on ratings volume (195K vs 6) and chart position (#71 vs unranked). iSometric 3D Form's advantage is in-app purchases (none vs 10) and ads (none vs shown). On price, update cadence, device support and iOS requirement there is nothing between them.

Both are free to download. Nonogram.com sells 8 one-off in-app purchases. iSometric 3D Form asks for nothing beyond the download.

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.

iSometric 3D Form ships an update monthly, Nonogram.com every 5 weeks. The most recent releases landed on October 15, 2026 and October 19, 2026 respectively.
