计算器APP其实是一个很普通的应用程序,然而我发现大部分计算器工具的体验,却是一言难尽: 「要么是很难看,要么是很难用,要么是很简陋...」,始终都没能让自己满意。 于是,我决定自己动手开发了一个计算器:真好算。 真好算的定位:为普通用户提供极致的日常计算体验。不需要很复杂的功能(但要很实用),不需要很高大上的界面(但要很耐看),我觉得我目前是做到了。 真好算的所有功能都集中在首页,一键触达。计算数字按钮整体靠下,十分适合单手操作。 其中,我最喜欢真好算的一个功能是:首页顶部横条支持显示最近10次(可自定义数量)历史计算记录。它既方便了你的下一次参考,同时又不像其他计算器那样过度干扰界面,真正做到了兼具简洁和实用。 此外,计算器首页的中间位置,直接集成各种实用工具的功能入口,一键触达。例如:金额大写、年龄生日、日期倒数、房贷计算、货币汇率、单位换算、世界时钟、BMI计算等功能,同时支持按自己的喜好手动排序,方便又实用。 另外,最重要的是:无广告无弹窗。 真好算目前主要功能: - 计算步骤 - 计算记录 - 金额大写 - 年龄生日 - 日期倒数 - 货币汇率 - 房贷计算 - BMI计算 - 世界时钟 - 单位换算 联系开发者: linguny@gmail.com
