About this app

AgChemicalCalc – Your Field Chemical Calculator

AgChemicalCalc is the ultimate tool for farmers, agronomists, and spray operators who need precise, reliable chemical calculations for their fields and sprayer tanks. Designed for simplicity and accuracy, this app allows you to calculate chemical requirements quickly and efficiently — entirely offline. The benefit of this app is no complex and expensive farm management software required, just a lightweight pdf reader and calculator. Currently Image based PDF's are not supported.

Avoid unreliable, inconsistent AI-generated results.
This app performs all calculations locally using fixed formulas, ensuring the same accurate result every time. No AI processing, no internet connection, and no variation — just consistent, repeatable spray calculations you can trust.

Key Features:

Works Offline: No internet connection required. All calculations are performed locally on your device.

Supports Multiple Units: Works with kg, L, qt, gal, and more, allowing flexibility across regions and chemical types.

Easy PDF Input: Upload standard chemical order PDFs, and the app parses chemical names and application rates automatically.

Accurate & Safe: Designed for real-world agronomy applications. Always double-check PDF formats, but calculations are precise and ready for practical use.

User-Friendly Interface: Simple, clean, and clear interface with color-coded results, making it easy to read and use in the field.
