轻松设置自己的计算应用程序！创建公式并根据需要运行它们
应用信息
应用描述
Android应用分析和审查：Custom Formulas，由BinaryEarth开发。在工具类别中列出。当前版本为9.2，在 17/06/2025 上更新。根据用户在Google Play上的评论：Custom Formulas。超过5 千的安装。 Custom Formulas目前有81评论，平均评分为4.1星
这个功能强大的应用程序可让您创建自己的自定义公式，然后通过提示您输入值来使用它们执行计算。此应用程序易于使用，但与更简单的应用程序不同，多个输入值可以输入多个公式，并且可以显示多个输出值。通过使用相同的变量名，可以将组中一个公式的输出馈送到下一个。
可以将相关公式分组，以便于查找。例如数学公式，测量公式，贷款利息公式等。
可以更改显示给用户的变量顺序，也可以更改输出字段中显示的精度的小数位数。
该应用程序预装了三个示例公式。按照复杂度递增的顺序，它们是：斜率百分比、复利和点比例因子。还有越来越多的公式可以轻松地从网络共享中心直接下载到应用程序中。当前类别包括健康、金融和测量。
公式组可以导出或通过电子邮件发送，允许您与应用程序的其他用户共享您的创作。
使用相同公式的多次计算结果可以保存到 CSV 文件中，以便以后在电子表格中查看。您还可以选择使用 sigma 按钮计算其中一个输入变量的一系列值的公式总和。
除了计算公式外，主页菜单上还有计算器工具和线性方程求解工具。

I was originally looking for a programming app when I found this one. I watched the video and this is above and beyond the functionality I was initially seeking! I would love to see more in depth documentation or a user manual. I received developer feedback on the usage of the 'if()' statement. Turns out I was not using it correctly. Update: The developer replied to my email with some excellent feedback and examples! Now 5 stars!

Its good but still needs tweeking. I like the app and it's functionality, the biggest issue I have is it keeps forcing every number I input and the outputs, into scientific notation, including constants I put into formulas, which isn't an issue if that's what you want. But I don't always like using SN, because sometimes I just need to see my actual numbers without having to do the extra rearrangement in my head, especially if I'm a bit tired. Needs an option to fully disable SN.

The ability to do custom formulas with input and output labels have help me at work when I have multiple components to cut intos sets to fit into various sizes on the fly.

Excellent app, but, what would make it even better would be the app database saved somewhere that doesn't need root to play around with. I find it easier to edit the database on the PC. That way I also have a backup copy. Any chance this could be done?

I've just spent the last few hours making formulas for tabletop RPG damage calculations and Level Ups. This is amazing! It's easy to learn, but remember to use * and / instead of × and ÷, or your formulas won't run.

Simple and effective! I still didn't try it with longer and complex formulas, but for some basic ones it works perfectly.

Awesome graceful setup of my new formulas. Now I can make those little formula-calcs I used to scrounge the whole store for.

Great app that only need one more thing: automatic backup on Google Drive.
