# SketchUp vs Deck Flows

The clearest difference is review sentiment: Deck Flows at 100% against SketchUp's 37%. Deck Flows also leads on rating (5.0 vs 4.5) and update cadence (daily vs every 3 weeks). SketchUp's advantage is ratings volume (18K vs 2) and chart position (#121 vs unranked). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. SketchUp sells 3 in-app purchases, starting at $11.99 per month and Deck Flows sells 2 in-app purchases, starting at $12.99 per month. Whichever you choose, the download price is not the number that matters.

Deck Flows holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: SketchUp has 18K ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 37% of SketchUp's written reviews are positive against 100% of Deck Flows's.

SketchUp ships an update every 3 weeks, Deck Flows daily. The most recent releases landed on October 16, 2026 and October 1, 2026 respectively.
