Identify your grass from a photo. Check weeds and brown spots for likely causes. Get a weather-aware lawn plan built for your yard.
What Grass Is This? brings grass identification, lawn problem guidance, and a practical care plan into one app. Start with a scan. Confirm your grass type. See what your lawn needs next.
IDENTIFY YOUR GRASS
Take a clear photo of your lawn. The app identifies common U.S. grass types and asks follow-up questions when the result needs more information.
CHECK WEEDS AND BROWN SPOTS
Photograph a problem area to check likely causes such as weeds, drought, disease, heat stress, or mowing damage. Get clear guidance and a practical next step. When a problem needs local expertise, the app directs you to an extension office or lawn professional.
GET A PLAN FOR YOUR LAWN
Build a plan from your grass type, ZIP code, lawn size, sun exposure, soil temperature, and local weather. See what to do this week, why it matters, and what comes next. Your plan covers mowing, watering, fertilizer, weed prevention, overseeding, dormancy, and seasonal changes.
TIME WORK BY WEATHER AND SOIL TEMPERATURE
Watch local conditions for pre-emergent, seeding, fertilizer, watering, and mowing windows. Use reminders to act closer to the right time.
READ A SOIL TEST
Upload a soil-test PDF. See the extracted values, plain-language interpretation, and recommended actions. Premium can save the result to your lawn and connect it to your plan.
MEASURE AND CALCULATE
Measure your lawn and calculate fertilizer, seed, watering, and other lawn-care needs. Save your lawn details so you do not enter them again.
TRACK WHAT WORKED
Log photos, mowing, watering, treatments, soil tests, and notes. Build a private lawn journal that shows how your yard changes through the season.
USE WIDGETS AND APPLE WATCH
See your next lawn task from a Home Screen widget. Check soil temperature and timing status from your Lock Screen or Apple Watch.
FREE TO START
Start with grass identification, lawn setup, calculators, and your first lawn-care task. Create an account to save your lawn and results.
PREMIUM
Premium adds unlimited grass and problem scans, the complete season plan, weather-aware alerts, diagnosis history, lawn health tracking, saved soil tests, and more.
No in-app ads. Saved lawn photos and journal entries are stored in private account storage and are not public unless you choose to share them. Photos that you scan are sent to our AI service for analysis.

Ratings & Reviews
What's new in version 1.2.12
Home now pages through this week's moves one card at a time. Swipe up to see what comes next, tap any card to open it, and the dots keep pace as you scroll.
- The Today's move widget shows the same move, the same next step and the same colours as the app.
- VoiceOver users can page the stack and hear every card, chip and counter on Home.
- Switching lawns opens on that lawn's move, not the last one you looked at.
Fixes: the stack respects Reduce Motion, cards no longer stay faded after a task completes, and lapsed subscriptions are handled correctly.
Thanks for using the app. If you've got feedback or a feature wish, reach out via Settings, then Help. We read every one.
