## What is Sprayer Calibration Pocket?

Sprayer Calibration Pocket is an offline field calculator for applicators, growers, turf crews, and land managers who need quick spray math before filling a tank.

Use it to:

- convert nozzle flow, speed, and spacing into gallons per acre
- estimate total boom width and system gallons per minute
- calculate tank acres from the current tank size
- turn a label rate per acre into total product ounces for the tank
- share a plain-text calibration sheet for a crew note or job folder

Why people pay for it:

- spray mistakes are expensive and often happen at the truck, not at a desk
- the app combines nozzle, boom, tank, acreage, and mix math in one offline sheet
- no spreadsheet setup, account, ads, subscription, analytics SDK, or server dependency

Sprayer Calibration Pocket is a math aid only. Always follow the product label, local rules, required protective equipment, equipment manuals, weather limits, and trained applicator judgment before applying any product.
