Know your yard.
Never miss a window.
GreenKeep is a soil-temperature-driven lawn care app for iOS. We watch local 2" soil temp and the 7-day forecast, then tell you exactly when to apply pre-emergent, fertilizer, or seed — based on real conditions, not a generic calendar.
What's different
Lawn care timed by the soil, not the calendar.
Every other app or guide picks a date and hopes the weather plays along. GreenKeep watches your zip's soil and forecast and tells you the day to act.
Real soil data
Most guides say "apply pre-emergent in March." We say "apply when soil hits 50°F at your zip — and it'll get there this Saturday."
Forecast-aware tips
"Rain forecast Tuesday — apply Monday for free activation." Smart timing tips that watch the next 7 days, not just today's weather.
Garden bed tracker
Beyond the lawn. Log plantings, waterings, fertilizers, pruning. See what you did, when, and what's due — across every bed in your yard.
Quiet by default
Maximum 3 alerts per week. We only notify when conditions actually line up — not because seven days have passed since the last ping.
Built for your zip
Cool-season grasses (fescue, Kentucky bluegrass) trigger differently than warm-season (bermuda, zoysia). GreenKeep knows the difference and times each task to your grass type.
Privacy-first
We use your zip code, not your location. No ads, no data sales. Your account history is yours alone, deletable any time from inside the app.
How it works
Three steps. No spreadsheets.
Tell us your zip and grass
Two taps in onboarding. We pull local soil data from Open-Meteo and stop bothering you about microclimate guesswork.
We watch the conditions
Daily soil temperature, twice-daily 7-day forecast. Trigger thresholds for every common task — pre-emergent, spring fert, overseed, aerate, winterize.
You get the right alert at the right time
One push, with the soil temperature, the forecast context, and a specific recommendation. Tap to view details, mark complete, snooze, or skip the season.
