Spray Sketch is a field-ready tool for agricultural spray operators and farmers. Draw spray areas over a satellite map with your finger. Every stroke autosaves on the device and remains available offline.
Important
- Acreage is an estimate based on your freehand drawings. It is not a legal survey.
- Spray Sketch is not a replacement for official product labels, regulatory compliance checks, or licensed drone flight planning.
- Always follow the pesticide label, applicator regulations, and any drone or aviation rules that apply in your area.
- Satellite imagery may be out of date. Always ground-truth.
