# Unit Converter vs 单位转换器

The clearest difference is in-app purchases: 单位转换器 at none against Unit Converter's 1. 单位转换器 also leads on update cadence (every 2 days vs every 2 weeks). Unit Converter's advantage is ads (none vs shown) and iOS requirement (12.0 vs 16). On price and device support there is nothing between them.

Both are free to download. Unit Converter sells 1 one-off in-app purchase. 单位转换器 asks for nothing beyond the download.

Unit Converter ships an update every 2 weeks, 单位转换器 every 2 days. The most recent releases landed on October 25, 2026 and October 19, 2026 respectively.
