# FieldFab vs 3D modeling

The clearest difference is in-app purchases: FieldFab at none against 3D modeling's 6. 3D modeling's advantage is ratings volume (15K vs 79) and review sentiment (68% vs 50%). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. 3D modeling sells 6 in-app purchases, starting at $5.99 per month. FieldFab asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.5 for FieldFab against 4.6 for 3D modeling. That said, the two scores are not equally well evidenced: 3D modeling has 15K ratings behind it against 79, so its average is the more settled of the two. Written reviews are what separate them: 50% of FieldFab's written reviews are positive against 68% of 3D modeling's.

FieldFab ships an update every 6 weeks, 3D modeling every 2 months. The most recent releases landed on November 3, 2026 and November 10, 2026 respectively.
