Homeowner struggles to water a 48x62 ft lawn efficiently, getting only 1/8" to 1/4" of water after 90 minutes and calculating a need for 9 hours to achieve 1/2" coverage due to low hose flow rate.

Workarounds Described

• uses tuna cans to measure water depth after running sprinkler
• times how long hose takes to fill a gallon to calculate flow rate
• manually calculates gallons needed and required runtime

Implied Software Gaps

• Auto-calculated sprinkler runtime based on lawn dimensions, flow rate, and desired water depth
• User-friendly flow rate measurement without manual timing
• Integration with smart controllers to automate watering schedule

LawnSprinkler Calc

A mobile app that calculates optimal sprinkler runtime based on lawn dimensions, hose flow rate, and desired water depth. Simply input your lawn shape and size, measure hose flow rate using a guided timer, and the app tells you how long to run each zone to achieve uniform coverage. Syncs with smart sprinkler controllers for automatic adjustment.
