I made an all-in-one calculator for Androud using Java, and called it Kalkulator

[masesm]

Hello everyone,
I spent the last month working on a project deem useful to my own major in college. I'm an engineering major, so math, programming, and conversions were constantly demanded and used. I wrote my own app that pretty much does everything I mentioned. I used java, and only java, and use both eclipse and android studio as my IDEs. I would have made the app available for iOS as well, but I soon found out I cannot develop apps on Windows PCs (bummer). But if I get a Mac, I definitely will. If you have the time, install the app, try it and give me feedback on it. I would like to know how to improve it, and what new things to add, and if I would be more than happy to answer any questions about the project. Thanks.

I know you're not trying to make a living from this thing but immediate things that came into thought anyway:

- Need some clear instructions how to use the Graphing Calculator. It's not very intuitive right now.
- No option to buy the app to remove adds.
- Needs more features for the scientific calculator. Maybe make some scroll bar. You could also for example introduce holding down 'sin' makes it into 'asin' and so forth for the other trig functions. Also needs atan2 and a bunch of other shit.
- Could need some graphical work on the scientific calculator itself. Look at the standard calculators.

-I'm not sure if you saw it, it's easy to miss, there is a gray question mark button in the bottom-left corner. It opens a custom webpage: [url]http://masesk.com/kgraphmanual.html[/url]. It should have all the commands there, but if you're saying that the page is not clear enough, you can elaborate on that and tell me how to fix.
-I'm working on that as an update. I initially was not going to include ads at all, but I wanted to try it, and learn how to implement the ad api into the app. If you think I should, I will definitely add it. Else, I'm mostly going to remove ads.
-The standard calculator was a challenge. I used the built-in XML layout for Android Studio, which I have/had zero experience on. I ended up using RelativeLayout with each button aligning to the next, that way bigger size screens can keep the same button size, but increase the middle margin. However, this whole delima was because I wanted to keep all the buttons square. If not, then a TableLayout will make all the buttons wide enough to fit the screen, with as many buttons on each line as I want. If anyone else knows of any other solution, let me know. I really appreciate your feedback. It means a lot to hear feedback from other programmers.

PS: I'm already working on new operations which include: factorial, x^2, asin, acos, atan, e, e^x, sinh, cosh, tanh.
