# CAD Smart Modeling vs Graph Paper

The clearest difference is rating: CAD Smart Modeling at 3.5 against Graph Paper's 2.8. CAD Smart Modeling also leads on iOS requirement (13.0 vs 18.0). Graph Paper's advantage is in-app purchases (none vs 7) and ads (none vs shown). On price, ratings volume and device support there is nothing between them.

Both are free to download. CAD Smart Modeling sells 7 in-app purchases, starting at $3.99 per month. Graph Paper asks for nothing beyond the download.

CAD Smart Modeling holds the better App Store score, 3.5 against 2.8. Both are backed by a comparable volume of ratings — 10 and 8 respectively. Written reviews complicate that: 0% of CAD Smart Modeling's written reviews are positive against 25% of Graph Paper's, so the app with the better star average is not the one people write more warmly about.

CAD Smart Modeling ships an update every 5 months, Graph Paper daily. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
