Sprinkler Score: Lawn Audit

Measure once. Water right. SprinklerScore guides you through a simple catch-can test, then turns your measurements into a clear picture of how evenly a sprinkler zone applies water. NO SPECIAL HARDWARE Use identical catch cups, tuna cans, or other straight-sided containers. SprinklerScore is hardware-neutral and works with any sprinkler brand. A GUIDED FIELD TEST • Inspect the zone for obvious faults • Choose your test length and number of cups • Run the built-in timer • Enter each cup reading as you collect it • See outlier warnings before calculating RESULTS YOU CAN ACT ON • Distribution Uniformity of the Low Quarter (DULQ) • Average catch depth and precipitation rate • Runtime for a target depth you provide • A separate dry-quarter runtime for diagnosis—not an automatic recommendation • Estimated gallons when you enter a zone area • Notes about wind, runoff, and visible sprinkler issues RETEST AND COMPARE Save a baseline, make an adjustment, and repeat the same setup to see whether coverage improved. Generate a clean PDF for one audit or share all readings as CSV. PRIVATE BY DESIGN Your audits stay on your iPhone. SprinklerScore has no account, ads, analytics, tracking, location access, or developer-operated data server. Reports leave the app only when you choose to share them. FREE AND UNLIMITED Every audit, repeat test, comparison, PDF report, and CSV export is included. No purchase or subscription. SprinklerScore is an educational measurement aid, not a certified irrigation audit. Results do not account for plant demand, weather, soil, slope, local restrictions, or equipment safety. Supply a target depth from a trusted local source and consult a qualified irrigation professional when needed.
