# HTM vs 计算器

The clearest difference is update cadence: 计算器 at every 2 months against HTM's every 35 months. HTM's advantage is iOS requirement (12.0 vs 14.0). On price, ads, in-app purchases and device support there is nothing between them.

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

HTM ships an update every 35 months, 计算器 every 2 months. The most recent releases landed on September 16, 2026 and September 17, 2026 respectively.
