TANK MIX CALCULATOR Enter your tank size, total acres, and target gallons per acre. Add as many chemical products as your mix requires — herbicides, fungicides, insecticides, or fertilizers — in any unit (oz, pt, qt, gal, lb). SprayCalc Pro instantly shows you: • Exact ounces, pints, quarts, and gallons of each product per tank • Water fill per tank • Total product needed for the entire job • Acres per tank and total tanks needed • Partial tank callout when acreage doesn't divide evenly NOZZLE & SPEED CALCULATOR Two powerful modes to dial in your application: • Find Target Speed — enter your nozzle GPM, spacing, and target GPA to get the exact MPH to drive • Find Actual GPA — enter your current speed to see the real gallons per acre being applied Includes boom width, total flow, acres per hour, a speed vs GPA reference table, and alerts when you're outside safe operating ranges. SAVED MIXES Save your go-to tank mixes and reload them in seconds. Tap any saved mix, enter a new acreage, and the app instantly recalculates per-tank amounts. Your mix library is always with you. FIELD HISTORY LOG Keep a complete record of every spray job: • Field name, date, and spray type • Acres, GPA, tank size, and tanks used • Every product applied with rate and total amount • Weather conditions at time of application • Notes and observations Log jobs directly from the calculator results screen, or enter them manually.
