www.irritracker.com Below is a email response asking for more information on this product: Our definition of map is two fold. Our form helps you create zone description maps from your phone or computer. The form includes information such as zone number, head type, plant material type, and zone location description. It also includes fields for customer name, address, phone number, controller location, and water source information. Secondly, Irritracker allows you to upload as builds, hand drawn maps, or color shaded maps into the form as a file (ex: .jpg file). Although it works on your phone, in my opinion this function is more usable on a tablet pc (ex. Ipad, Toshiba Thrive, etc.)(Irritracker works on all these devices!!). The bigger screen size allows you to expand out and see more detail in the uploaded image. Irritracker was created to work on your mobile phone out in the field. Therefore, the forms are designed to be simple, easy to read, and easily updated from your mobile device.
