Description

This powerful app lets you create your own custom formulas and then perform computations using them by prompting you for the input values.

This app is easy to use, but unlike simpler apps, multiple entered values can be fed into multiple formulas and multiple output values can be displayed. The output of one formula in a group can be fed into the next by using the same variable name.

Related formulas can be grouped into categories to make them easy to find. e.g. Maths formulas, Surveying formulas, Loan interest formulas etc.

The order of variables displayed to the user can be changed, as can the number of decimal digits of precision shown in the output fields.

Three example formulas are pre-installed with the app. In order of increasing complexity they are: slope percentage, compound interest, and point scale factor. There are also a growing number of formulas available to easily download directly in the app from a web sharing hub. Current categories include health, finance, and surveying.

A formula group can be exported or emailed, allowing you to share your creations with other users of the app.

The results from multiple computations using the same formula can be saved to a CSV file for later viewing in a spreadsheet. You can also choose to compute the sum of the formulas for a range of values of one of the input variables using the sigma button.

In addition to evaluating formulas, there is also a calculator tool and a linear equation solving tool on the main page menu.

Questions & Answers

Q: What is an APK File?

A: Just like Windows (PC) systems use an .exe file for installing software, Android does the same. An APK file is the file format used for installing software on the Android operating system.

Q: If I install an APK from this website, will I be able to update the app from the Play Store?

A: Yes, absolutely. The Play Store installs APKs it downloads from Google's servers, and sideloading from a site like ApkClean.net goes through a very similar process, except you're the one performing the downloading and initiating the installation (sideloading).
As soon as the Play Store finds a version of the app newer than the one you've sideloaded, it will commence an update.

Q: Why ApkClean.net can guarantee APK 100% safe?

A: Whenever someone wants to download an APK file from ApkClean.net, we'll check the corresponding APK file on Google Play and allow user download it directly (of course, we'll cache it on our server). If the APK file does not exist on Google Play, we'll search it in our cache.

Q: What are Android App permissions?

A: Apps require access to certain systems within your device. When you install an application, you are notified of all of the permissions required to run that application.

5 ★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.
5 ★Just what I needed, this is a really excellent app and very intuitive!
5 ★It was a hard decision to buy it even with it on sale given I likely had 30 calculators on my android anyways. However, I didn't have a program-your-own formulas app so I got it. One of my first formulas tried was statistics based sum of a series and discovered SUM function not supported so I guess asking for more support of math functions is where to start asking as far as improvements. Developer added SUM immediately on my behalf. It's about 2yrs later and I don't regret buying it one bit.
5 ★👍
5 ★Awesome graceful setup of my new formulas. Now I can make those little formula-calcs I used to scrounge the whole store for.
5 ★Awesome app, it just takes a little bit of time to figure out how to put in all the information.
5 ★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?
5 ★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!
5 ★Good
5 ★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.
