# WindowDraw vs 慧算房

The clearest difference is in-app purchases: 慧算房 at none against WindowDraw's 3. 慧算房 also leads on update cadence (every 8 days vs every 2 weeks). WindowDraw's advantage is ratings volume (8 vs 1) and iOS requirement (13.0 vs 15.0). On price, rating, ads and device support there is nothing between them.

Both are free to download. WindowDraw sells 3 in-app purchases, starting at $9.90 per month. 慧算房 asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.9 for WindowDraw against 5.0 for 慧算房. That said, the two scores are not equally well evidenced: WindowDraw has 8 ratings behind it against 1, so its average is the more settled of the two.

WindowDraw ships an update every 2 weeks, 慧算房 every 8 days. Both last shipped on October 24, 2026.
