# 3Dskope vs PDF

The clearest difference is price: PDF at Free against 3Dskope's $3.99. PDF also leads on rating (4.0 vs 3.3) and update cadence (every 2 months vs every 6 months). 3Dskope's advantage is ratings volume (3 vs 1). On ads, in-app purchases, device support and iOS requirement there is nothing between them.

PDF is free to download; 3Dskope costs $3.99 up front. 3Dskope sells 8 one-off in-app purchases and PDF sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

3Dskope ships an update every 6 months, PDF every 2 months. The most recent releases landed on October 23, 2026 and October 28, 2026 respectively.
