# ShapeScale vs Styku

The clearest difference is rating: Styku at 4.7 against ShapeScale's 4.0. Styku also leads on ratings volume (250 vs 43). ShapeScale's advantage is in-app purchases (none vs 3) and update cadence (weekly vs monthly). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. Styku sells 3 in-app purchases, starting at $49.99 per 3 months. ShapeScale asks for nothing beyond the download.

Styku holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Styku has 250 ratings behind it against 43, so its average is the more settled of the two. Written reviews complicate that: 58% of ShapeScale's written reviews are positive against 56% of Styku's, so the app with the better star average is not the one people write more warmly about.

ShapeScale ships an update weekly, Styku monthly. The most recent releases landed on September 10, 2026 and September 24, 2026 respectively.
