Chemcalc
Read full descriptionHide full description
Chemcalc is a practical spray planning app for farmers, contractors, and agronomists working in New Zealand and Australia. It helps you work out application rates, tank loads, and product totals quickly and clearly, so you can spend less time on arithmetic and more time in the field. Use the spray rate calculator to plan a job from the basics that matter: area, water rate, product rate, tank size, and equipment. Chemcalc works out how much product you need, how many tank loads are required, and keeps the maths consistent as you adjust inputs. You can save completed calculations and open them again later when you need to repeat a job or check what you used last time. Build a library of your own chemicals with label information at hand. Add and edit products, attach photos, and open label PDFs when you need to confirm rates, restrictions, or other label details. Label PDFs can be saved locally after you view them, so they are available again even when you are offline. Rates from labels can be applied in the calculator to reduce manual entry and mistakes. Create tank mixes that combine several products into one recipe, and save spray equipment profiles for tractors, trucks, helicopters, and other setups with tank capacity, speed, and boom width. The flow rate calculator helps you turn a single nozzle measurement into total flow and application rate, which is useful when checking or setting up application equipment. When you need transport paperwork, Chemcalc can help you draft a dangerous goods consignment note from a saved job and label data, pulling together the shipping information required for moving agricultural chemicals. Chemcalc supports both metric and imperial units, so you can work in hectares or acres, litres or gallons, and the product units that suit your operation. The app is designed to be straightforward on phone and tablet, with a clean layout and tools grouped on the home screen so common tasks are easy to find. If something is missing, incorrect, or you want a product added, you can send feedback directly from the app without setting up email on your device. Chemcalc is built for real spray work in NZ and AU conditions, with label-aware tools, saved workflows, and calculators that fit how spraying is actually planned and checked in the paddock or on the road.
