Formula Calculator Equreka for Android
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.
Please note that this app is designed for phone with > 512MB RAM. If your RAM is 512MB or less, it may crash upon loading due to not enough RAM to load all of the formulas

Creating Equations / Formulas tips
- Equreka support variables from a to z (26 variables) in case sensitive typography. Uppercase letter (A to Z) are not supported
- Please use standardized Equation Naming Convention for equation name you may create. The standard equation name are like this: "(topic specific) (end result) BY (variables) IN (dimension)". For example: "photovoltaic capacity factor by energy production and peak sun hour in metric"
- use 'equation tag' to store any keyword that didn't fit into 'Equation Name'. For example equation common name like "Newton Third Law" or "relativity", equation topic like "high school physics", "thermodynamic" and etc
- due to library bug, please avoid to use ( ) as bracket. Use [ ] and { } instead. ( Bracket ( ) still will be calculated correctly but the equation may be displayed incorrectly in equation string renderer due to this bug)
- always use asterix ( * ) as a multiplication operator ( x ). using dot ( . ) or omitted it completely will result in uncontrolled manner. Example: write 2*b instead of 2b to calculate 2 multiplied with b

Notes:
if you really want these pro version features, but you didn't have money to buy it (maybe because you already struggle for daily life, too poor to afford, have big debt to bear, or something like that), don't worry. Just contact me. I'll give you code to unlock your Equreka to become Equreka Pro. For Free.
Put in (a+b)/2 with a = .18 b = 1.62 it gave answer as .81? What???? I was using this as part of a bigger equation first and kept getting the wrong answer.
Missing round () function, floor and ceil are great if you know your decimal should be upped or downed, but if it needs to follow a standard rounding principle then we're screwed.... Also there's the issue with the floor function, other than that, love it, easy to use and easily customized
Very Nice Formula Usable Calculator, How to Convert Round Figure of Final Answer. How use formula to another formula. like a(Fx)=b+c another formula use d(Fx)=a+d use same in single formula
Dude somebody is going to have to explain how to work this this is not what I was expecting
Usage of Floor Function gives "Repeating Letters Error". Kindly fix. Also please increase the Font-Size of Digits we input in the variables. Thanks.
Very good....
cool :-)
Very good app.
Great
May I ask where you have obtained the formulae for photovoltaic panel tilt?
Manteb gan Jimbus, kayanya ini bakal jd calc terbaik di PlayStore
Try to input normal distribution equation could not save it. Could not navigate back to main formula screen. Pi symbol missing
Because i think it's okay. I didn't download it. But i will download it later.
Very goooooooood
Mantabs gan..
There is so much more expressions then I was looking for but it's fun to try the ones I don't know.
The best math program created.
Very use full appeal
Awesome
It is Buggy worth nothing. Language dose not retain Formulas do not done load Gui is not intuitive . Very difficult to work with it
Keren mas applikasi-nya.. :D
Best calculation tools I've ever download

Small size, but very powerful. It comes with a HUGE equation database, and you can save your own equation as well. Despite the extensive database, it only takes up around 8MB of space, very efficient. You can also see the equation and how the answer is obtained, so it is better than a calculator where you only see the results.
Mangstab gan
Good.. Bisa buat bantu ujian nih :D
This is good app , I like this, I hope you can develope this app
Ijin icip2 gan appnya..dari penjelasan di kaskus sepertinya menjanjikan sekali prospek kedepan..its a very usefull app.
Really helpful
Good app. Very like it.
Interesting concept, but it has never once successfully connected to the equation database, and refuses to continue.
Mantap bang
Good...
Wonderfull
Wow keren...bingit

Best programmable I have found so far but has a few problems. Floor does not work as found by another, pi is entered as a number, no rounding for results, after modifying cannot save as new function. Having said all that, I love the formula formatting and like it enough to want to pay for it and stop the adverts.
