# Calculator vs 长卷

The clearest difference is in-app purchases: 长卷 at none against Calculator's 4. 长卷 also leads on ads (none vs shown) and review sentiment (100% vs 70%). Calculator's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 27.0). On price there is nothing between them.

Both are free to download. Calculator sells 4 in-app purchases, starting at $2.49 per month. 长卷 asks for nothing beyond the download.

Calculator ships an update every 2 months, 长卷 every 3 weeks. The most recent releases landed on October 16, 2026 and October 6, 2026 respectively.
