    Hello new to the forum I hope this is the right place to post this. I am looking for a tutorial for a calculation app. I have tried to search around but it is only giving me calculator apps. A little more specific I want my customers to be able to enter 3 different figures and for the app to do some hidden calculations and come out with a number. I have a calculation setup in an excel file on my computer but it would make it much easier if my customers had a app on their phone. Anything close would be helpful. Thank you in advanced for any information leading to a decent tutorial on a calculation app

    "hidden calculation"" needs some clarification.

    You could do this with a custom made app, website. or Tasker.

    If "hidden calculation" means add then a Reverse Polish Notation calculator (I use Real Calc) would support something like the following to add 10, 5, 10 ...

    10
    Enter
    5
    Enter
    10
    +
    +

    ... Thom

    Just some calculations for in the background is all I really meant. So rather than my customers having to remember an equation they would enter their information and it would spit out the answer. My customers are farmers they sometimes will need to know how many gallons per minute they are putting down of fertilizer. So the "hidden calculations" would be the equation for that. I would like 3 boxes available for them to enter width of tool bar, speed they are traveling and rate at which they are putting down their fertilizer

    That could be done easily with a little javascript and a web page. Is there a reason you want to use an app?

    I want to build an app myself so that at a later time I can possible expand it. I was looking for a tutorial that will show me ow to do this or something similar

    You can probably do something with app inventor. They have tutorials here.

    If you wanted something quick you could look at this little volume calculator I put together to figure out the tons of stone needed to cover a driveway. You just need to adjust the titles and the math. :)

    Ooops, I forgot to embed the javascript in the header and had some funky functions in there. Cleaned it up for you now. :D
