Farm Spray & Tank Mix Calc
Dosage, calibration, mixing
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Mix every tank right: dose times area gives product per tank, water and the partial last fill. Nozzle calibration included. Works offline in the field.
The farmer's spray calculator — dosing, tank mixing and nozzle calibration in one honest tool.
Enter the label dose and your field size to get the exact amount of product to buy. Plan every sprayer fill: product and water per tank, tanks needed for the whole field, the area each tank covers and the partial last fill — ready to read back at the water source. Work in decares or hectares; dose, rate and area all follow one global unit.

• Mix a second product in the same tank
• Quick converters: decare ↔ hectare, liter ↔ milliliter, % ↔ g/L
• Save named recipes to history
• Share clean PDF recipe cards
Built for gloves and sunlight: big keypad, huge results, Outdoor Bright mode.
Everything stays on your phone — fully offline, no account, no tracking.
Always follow the product label — the label is the law.
