# sketchometry vs Geometry!!

The clearest difference is in-app purchases: sketchometry at none against Geometry!!'s 2. sketchometry also leads on ads (none vs shown) and update cadence (every 10 days vs every 7 months). Geometry!!'s advantage is ratings volume (56 vs 5). On price, rating, review sentiment and device support there is nothing between them.

Both are free to download. Geometry!! sells 2 in-app purchases, starting at $0.99 per year. sketchometry asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.6 for sketchometry against 4.5 for Geometry!!. That said, the two scores are not equally well evidenced: Geometry!! has 56 ratings behind it against 5, so its average is the more settled of the two. Written reviews are what separate them: 65% of sketchometry's written reviews are positive against 67% of Geometry!!'s.

sketchometry ships an update every 10 days, Geometry!! every 7 months. The most recent releases landed on October 12, 2026 and September 28, 2026 respectively.
