# Fit and Build vs Category Stack

The clearest difference is rating: Category Stack at 4.9 against Fit and Build's 2.0. Category Stack also leads on ratings volume (15 vs 1). Fit and Build's advantage is in-app purchases (none vs 10) and update cadence (every 2 days vs every 3 months). On price, ads and device support there is nothing between them.

Both are free to download. Category Stack sells 10 one-off in-app purchases. Fit and Build asks for nothing beyond the download.

Category Stack holds the better App Store score, 4.9 against 2.0. That said, the two scores are not equally well evidenced: Category Stack has 15 ratings behind it against 1, so its average is the more settled of the two.

Fit and Build ships an update every 2 days, Category Stack every 3 months. The most recent releases landed on October 25, 2026 and November 1, 2026 respectively.
