How it works

Two photos in. A plan out.

No guessing in the garden centre aisle. Grassly looks at your actual lawn, in your actual season, where you live.

  1. Photograph your lawn

    Stand back and take one photo of the area you want to fix. Daylight works best.

  2. Add a close-up

    Get down low for a sharp shot of the blades. That is how Grassly tells buffalo from kikuyu.

  3. Get your score and plan

    A health score out of 100, what is holding the lawn back, and next steps with real amounts.

Grass ID

Know your grass. Then care for it properly.

Most lawn advice depends on the grass you have. Grassly identifies it from a close-up and shows how sure it is. When it is not sure, it asks for a better photo instead of guessing.

  • Local names: buffalo, couch, kikuyu and Queensland blue couch in Australia.
  • Mowing height, watering and feeding for that grass.
  • Reference photos to compare against your own.
Buffalo · strong match 91%Mow 3–5 cm
Identification result: Buffalo, Stenotaphrum secundatum, strong match 91 percent, with traits such as wide, coarse blades and a 3 to 5 centimetre mowing height.

Every morning

One clear call for today.

Grassly reads your local forecast and soil temperature, then tells you what the lawn needs today: water, mow, feed or leave it be. One tap logs what you did.

  • A water ring that counts rain and sprinkler time against what the lawn uses.
  • A countdown to the next mow, from your grass and the weather.
  • Soil temperature windows for feeding, seeding and weed prevention.

Today's call card, Feeding window is open, above three rings: water 109 percent of this week's need, mow in 5 days, and soil at 19 °C.

Questions

Good to know.

Which grasses can Grassly identify?

The common lawn grasses: buffalo, couch, kikuyu, zoysia, Queensland blue couch, tall and fine fescue, perennial ryegrass, Kentucky bluegrass, bentgrass, centipede and more. When a photo is not clear enough, Grassly says so and asks for another one.

How accurate is it?

No app is right every time, so Grassly shows how confident it is on every result and lets you correct it. Its care advice follows published turf guidance for your grass, your season and your local weather.

What does it cost?

Grassly is free to download. Some features need Grassly Premium, a subscription you can cancel at any time in your iPhone's Settings under your Apple ID.

Does it work outside Australia?

Yes. Grassly adapts grass names, units and seasons to Australia, New Zealand and the United States.

Where does the weather come from?

Forecasts come from MET Norway, the Norwegian Meteorological Institute, for the town you choose. Grassly never needs your street address.

Start with one scan.

Two photos, and you will know what your lawn needs next.
