Hey everyone, Im not programmer but my brother in law is and We are going to start working on an iPhone app that could help us as applicators. This isnt a sales pitch or anything but Im just looking for your thoughts and opions weather its worth the time to create or not. What I had in mind was a chemical calculator. Say you need to find out how much N you need to put down in a lawn or say your mixing up a tank of chemicals and need to know how much of each chemical to to put in the tank, this would tell you that and do all the math for you. I would also eventually like to add in a database of non compliant chemicals so that you dont mix 2 chems that are incompatable with each other and also eventually a database that has all weed types and what/when/how the best way to kill them is. But I need your help also, like your thoughts on the whole thing and any ideas to make the app work for you and be a great resource. I also want to tap into the gps tracking of the iPhone so that way you can track your pattern and also your amount applied. Im not sure how accurate that is but I hope to try it out. I have a some other ideas that will further this app in a way I cannot say just yet but this would just be the foundation for something that could be huge. Please lets not turn this into a cepphone thread but in turn keep it based on your thoughts, recomndations and ideas on the app. Thanks!!
