Sprinkler Plan

Plan your sprinkler system with confidence.

Upload a photo of your yard, place your sprinkler heads, and visualize exactly what each head covers. Set a weekly watering goal and fine-tune head positions until every inch of lawn gets what it needs.

Features

• Visual layout — place heads directly on your yard photo and see coverage arcs drawn to scale in real time
• True-to-scale — calibrate using any two points with a known distance; every measurement reflects your actual yard
• Goal-based planning — set a weekly watering target (like 1 inch/week), then adjust head placement and zone run times until every zone hits it

How it works

1. Upload a yard photo — any aerial or top-down photo works; a Google Maps screenshot is perfect
2. Set the scale — click two points on the image and enter the real-world distance between them
3. Place sprinkler heads — add heads, assign zones, and adjust radius and arc angle to match your hardware
4. Dial in your coverage — set a weekly watering goal, then tune zone run times and head positions until the coverage map shows every area is hitting its target
