Every seed rate calculator asks you to type in an area. This one measures the field.

Walk around the field with GPS, trace it on the satellite map, or stand at each corner and let the app average the position. Seed Calc turns the real area into what you have to buy: seed in kilograms and bags from your rate per hectare, acre or bigha, fertilizer from your dose, and spray mix for the tank. The rates are yours: the app never invents a dose.

Acres, hectares, bigha, guntha, cent, marla, kanal, or your own unit, with composite display like 1 acre 40 cent. Export a PDF with the map to scale and the quantities, or share a single image. Save the map before you leave and it works without a signal. Reopen a field next season and measure it again. No account, no subscription: a single purchase removes ads.
