# Sketchalyze vs STRUCT

The clearest difference is update cadence: STRUCT at every 4 weeks against Sketchalyze's every 13 months. Sketchalyze's advantage is ratings volume (7 vs 1). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

On the App Store both sit at effectively the same score — 5.0 for Sketchalyze against 5.0 for STRUCT. That said, the two scores are not equally well evidenced: Sketchalyze has 7 ratings behind it against 1, so its average is the more settled of the two.

Sketchalyze ships an update every 13 months, STRUCT every 4 weeks. The most recent releases landed on September 13, 2026 and September 30, 2026 respectively.
