Best and most useful calculator ever!

I have used a lot of calculator apps in the past. This is the best and the most useful calculator app I have ever used. I am a landscape gardener and use a lot of calculations in my work. Especially, when I spray pesticides which involves a lot of calculations to determine the correct amount of products and in determining acreages, etc. I use this app constantly and helps make my job easier. I have an iPhone and an iPad and you must always keep the support and updates going. Keep up the good work.
