## Description

Built by a farmer, for farmers. Calculate tank mixes, find your target speed, save your go-to mixes, and log every spray job — all in one app.

SprayCalc Pro is the essential spray calculator for farmers, custom applicators, and agronomists. Stop doing math in your head or on scraps of paper — get your tank mixes right every time.
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. Filter by spray type, search by field name or product, and track season totals at a glance.
DISCLAIMER
SprayCalc Pro is a calculation aid. Always verify application rates against current product labels and consult a licensed agronomist for crop-specific recommendations. Follow all local regulations regarding pesticide application
