# Spool vs 3D PrintCost

The clearest difference is ads: Spool at none against 3D PrintCost's shown. Spool also leads on device support (3 vs 1). 3D PrintCost's advantage is update cadence (every 4 days vs every 2 weeks) and iOS requirement (17.0 vs 26.1). On price and in-app purchases there is nothing between them.

Both are free to download. Spool sells 3 in-app purchases, starting at $4.99 per month and 3D PrintCost sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Spool ships an update every 2 weeks, 3D PrintCost every 4 days. The most recent releases landed on October 10, 2026 and October 7, 2026 respectively.
