# Shapr 3D CAD modeling vs CRUMB

The clearest difference is price: Shapr 3D CAD modeling at Free against CRUMB's $7.99. Shapr 3D CAD modeling also leads on rating (4.7 vs 4.4) and ratings volume (34K vs 146). CRUMB's advantage is in-app purchases (none vs 6) and chart position (#79 vs unranked). On review sentiment, update cadence, ads and device support there is nothing between them.

Shapr 3D CAD modeling is free to download; CRUMB costs $7.99 up front. Shapr 3D CAD modeling sells 6 in-app purchases, starting at $32.99 per month. CRUMB asks for nothing beyond the download.

Shapr 3D CAD modeling holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Shapr 3D CAD modeling has 34K ratings behind it against 146, so its average is the more settled of the two. Written reviews complicate that: 52% of Shapr 3D CAD modeling's written reviews are positive against 56% of CRUMB's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly weekly. The most recent releases landed on November 8, 2026 and November 7, 2026 respectively.
