I can handle the UI but I need help with making calculation work. I need a very simple iphone and android app built that does PSI calculations based on ideal gas law. A user enters digits in three boxes, 1 a starting temp in Fahrenheit, 2 a staring PSI and 3 an ending temperature in Fahrenheit . The app uses the ideal gas law to come up with the ending PSI and presents this. I need the three boxes created, and the calculation to be done and the answer presented. I can handle the rest of the app. I have attached an excel spreadsheet and a word doc showing how the formula works so you can use that. I can handle making the UI look good but need the calculations to work.

Hello, I am a unity 2D c# developer. I have good competencies regarding 2D native games and applications. I have worked on 6 games so far and many of them are supposed to be launched very soon. I will be working on the project using unity 2D which will make it easier to transfer the app to various platform as android and windows , mac etc. too. You can design the UI in unity, its very fast and gets automatically adjusted with different screen resolution. I have read the description and is fully capable of making the app logic. I will also make a simple GUI with the app, you can then modify it in any ways you like. You may contact me for further discussions if you want. Regards, Abhishek Agrawal
