Is there a farming app that works in Ouallam?

Divisi does. It reads Ouallam's own rainfall, soil and terrain rather than a national average, so the planting dates and crop shortlist on this page are the same ones the app works out for a field here — then dates each job for that field, and keeps working with no signal.

Is this exact for my own field?

No — these are readings taken across Ouallam, not on your field. Soil, slope and rainfall change from one farm to the next. Check your own location to see your own numbers.
