# Scripting vs STEP File Viewer

The clearest difference is rating: Scripting at 4.9 against STEP File Viewer's 4.0. Scripting also leads on review sentiment (98% vs 63%) and ratings volume (112 vs 4). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Scripting sells 3 in-app purchases, starting at $0.99 per month and STEP File Viewer sells 12 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Scripting holds the better App Store score, 4.9 against 4.0. That said, the two scores are not equally well evidenced: Scripting has 112 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 98% of Scripting's written reviews are positive against 63% of STEP File Viewer's.

Scripting ships an update fortnightly, STEP File Viewer every 2 weeks. The most recent releases landed on October 15, 2026 and October 9, 2026 respectively.
