Built for lawns in Australia. Works with warm and cool season grasses.

Features
The whole season, in your pocket
Built around how your home lawn actually behaves: temperature drives growth, and growth feeds the obsession.
Daily GDD, done for you
Every night LawnDash takes the day’s max and min temperature for your postcode from BoM via WillyWeather and works out growing degree days. No thermometer required.
Weather data, rain and temperature
Daily highs, lows and rainfall for your area, with the last 7 days of rain and watering side by side. Rain over your threshold counts as a watering, or send readings from your own weather station.
A log of everything you’ve done
Mow, fertilise, wetting agent, pre-emergent, post-emergent, irrigate, aerate, dethatch, even sharpening your mower blades. Every action is dated and sits on the day it happened, next to that day’s weather.
Australian products, with label rates
A catalogue of products from Syngenta, Turf Culture, SureFire, Lawntips and more, each with its label rate, rates by grass species and a warning where it isn’t suitable. Missing one? Send us a link and we’ll add it.
Dose by the square metre
Pick a product or a saved recipe with multiple products together, enter the area, and get the amount to mix. Rates that differ by grass variety are handled for you.
Zones and Recipes
Split your lawn into zones, each with its own grass type. Save the mixes you keep coming back to as recipes and reuse them in a tap.
Reminders and GDD warnings
Schedule any job to repeat - weekly, monthly, or growing season only and set a GDD threshold. Get a push, an email or even a Telegram message when it’s time.
Lawn care plans
Pick a seasonal plan from the library and it lands on your calendar as scheduled tasks, on your “yard work” days. Apply it to the whole lawn or a single zone.
History that starts before you do
Sign up and LawnDash backfills the last month of weather (from Apple Weather) for your area, so your GDD count is already running on day one.
Home Screen widgets
See the week’s water, GDD progress towards your warning, what’s scheduled and when to water next, straight from your Home Screen.

Since 2020
Built in a Perth backyard
LawnDash started as a spreadsheet, a Home Assistant sensor and a little .NET API called TurfManager. Six years of mowing later, it's the app I always wanted.
