# 材料成本計算器 vs MT訂單日曆

The clearest difference is in-app purchases: 材料成本計算器 at none against MT訂單日曆's 1. MT訂單日曆's advantage is ads (none vs shown) and update cadence (daily vs every 12 months). On price, device support and iOS requirement there is nothing between them.

Both are free to download. MT訂單日曆 sells 1 one-off in-app purchase. 材料成本計算器 asks for nothing beyond the download.

材料成本計算器 ships an update every 12 months, MT訂單日曆 daily. The most recent releases landed on October 30, 2026 and November 5, 2026 respectively.
