Lawn Calc
Enter your sprinkler once. Each zone gets its minutes per watering.
Scan with your phone to install
Under Sprinkler, enter its Precipitation rate in inches per hour, or its Flow rate in gallons per minute. Do not know the rate? Set a few cans on the lawn, run the sprinkler for 15 minutes and multiply the average depth by 4.
Choose the Water per week, rain included — 1 inch by default — and the number of Waterings per week. Each zone shows its minutes per watering, for example "30 min per watering, 2× a week".
The square footage of your grass, zone by zone, measured on the satellite photo.
A typical program for your grass type, a reminder on the morning of each step, and nothing you cannot change.
Copy the rate from the bag. Lawn Calc counts the pounds for each zone and the bags for the whole lawn.
Every mowing, watering and bag spread, with the year's totals.
Beyond fertilizer: what to buy to overseed, lime, sod or topdress, from the area you measured.
No account, no server of ours. Here is everything the app sends over the network.
Draw it on the satellite photo, then let the schedule tell you what to spread and when.
