# AutoCAD vs CtrlSun

The clearest difference is rating: AutoCAD at 4.4 against CtrlSun's 1.0. AutoCAD also leads on ratings volume (6.3K vs 1). CtrlSun's advantage is in-app purchases (none vs 3) and update cadence (every 3 weeks vs every 2 months). On price, ads and device support there is nothing between them.

Both are free to download. AutoCAD sells 3 in-app purchases, starting at $9.99 per month. CtrlSun asks for nothing beyond the download.

AutoCAD holds the better App Store score, 4.4 against 1.0. That said, the two scores are not equally well evidenced: AutoCAD has 6.3K ratings behind it against 1, so its average is the more settled of the two.

AutoCAD ships an update every 2 months, CtrlSun every 3 weeks. The most recent releases landed on October 17, 2026 and October 7, 2026 respectively.
