Calculator apps?

[Wee Hooker]

So back in the 1980's , I had a calculator that allowed me to store frequently used formulas with variables.
For example:
The formula for volume could be stored then, when retrieved, it would ask you to input for variables for length, width, height.

I'd really like to duplicate that function with an app for my cell phone so that I could create and store commonly used formulas. ( For instance, Muzzle energy, triangle leg measurements etc.)

Does anyone know of an (android) app that can do such things?
I can't seem to find one with a google search.

If you are looking for an app. for volume, why? If you simply use the multiplication function you get the same thing! AxBxC=V Why do you need an app for that?

Go to the "Apps Store" on your phone and search calculator, you will find more different ones than you can imagine, some you have to pay for, many are free.

The OP asked for an app for multiple formulas........

Assuming you have an Android phone, have a look at this app: Equreka

Equreka Formula Calculator is an app to ease and quicken everyday calculation by storing your frequently used equation/formula into apps. If user want to perform calculation, the only things to do is open the formula and then enter its variables. Then, Equreka will calculate the equation & show the result.

The strong point of this app was, all formulas are not hard coded by developer. But freely customizable. It means, user could create, store, search, manage, edit, and execute his own equation / formula or current formulas already inserted on database.

We understand that creating a formula could become a complex task. So, we designed this app that to be as simple as possible. That's why equation / Formula in Equreka are created in one straightforward step by using "standard everyday" equation syntax. Just write the equation/formula intuitively, and then the apps parser will automatically detect which one is variable and which one is not. Save it, and the formula are ready to be used.

Currently, there are about 650+ formulas on database (and keep counting). Ranging from physics, math, finance, up to photovoltaic investment calculator. This apps could be very useful for engineer, students, scientist, professional and everyone who need to perform formula calculation frequently in their daily life.

Thanks! I think the Equrika app will work if I can get it to download.

There must be an app for downloading.

There must be an app for downloading.

Yes . . . quite a few, actually.

If you're used to HP, try "Go41C". Same as the HP 41 calculator. Works pretty well. As a Land Surveyor, I used to use the 41 all the time.

If you don't mind a full-blown graphing calculator on your phone, the app wabbitemu uses Texas Instruments OS to duplicate most of their calculators on android quite well!
All of the graphers are fully programmable for what you are doing. My current version of wabbitemu is 3 years old and going strong. Earlier versions were a bit flaky, and required starting over now and then. I think they may have the bugs worked out.
Get it? bugs wabbit,,,I know. But only someone around here would get it, so I had to say it.
