What LawnSuite does now, plus a calculator safeguard in an Android draft

I built LawnSuite around my own Sir Walter lawn on heavy clay in Ipswich. The useful part of an app, for me, is whether it answers the next question: does the lawn need water, what did I actually put on it, and did that job help?

Since the April launch posts, that's what I've been working on. There's also a calculator change worth explaining carefully, because it isn't everywhere yet: the batch-only behaviour described below is in the new Android build, currently in closed testing. It has not been verified as delivered to existing Play users, and the Web calculator doesn't share the change. That's the state of things as checked on 21 September 2026.

One of those April posts was my comparison of lawn care apps for Australian homeowners. It includes LawnSuite, the app I built myself, so keep that perspective in mind.

Watering starts with an estimate of what's in the soil

The watering balance now uses FAO-56 reference evapotranspiration to estimate weather-driven water use. Combine that with your lawn's turf and soil assumptions, and you get an estimate of how far its stored water has fallen below full.

It's a model, not a moisture probe buried under the buffalo. The grass and soil details you enter matter, and so does recording the watering you actually do. The watering advice is a Pro feature for eligible, configured lawn zones — creating a zone on its own doesn't supply everything the balance needs.

One rain distinction I want to be clear about. Forecast rain can change the watering advice, but automatic rain credit into the stored balance is currently off. A wet forecast and a measured refill are different things. Before you treat the screen as today's ground truth, look at the balance date, your recent watering and the lawn itself.

The assumptions behind a separate city comparison are in the FAO-56 versus weekly-rule article. That article is a climate-based comparison — it isn't a prediction of your next bill, and it doesn't walk through every step in the app's live balance. Local restrictions and permitted watering days still apply, whatever any screen says.

The program can move when the weather does

The seasonal programs start with grass type and Australian climate. The weather adjustment then gives scheduled work a chance to move when the forecast makes the original timing unsuitable — rain, wind and heat can all matter to different jobs.

This sits on the paid side of LawnSuite. The public calendar further down is a general guide; it doesn't keep a personal schedule or shift your saved jobs.

A rescheduled task isn't permission to use a product either. Check the current label, the conditions at your place and whether the lawn actually needs the treatment. The app can't inspect your backyard for you.

Finish the job, then check what happened

Treatment history is useful, but a completed tick doesn't tell you whether the lawn improved.

The care check-in flow on Android and Web connects eligible personal treatments to a later look at the result. You can record Better, Same or Worse, with an optional note or photo. If something isn't improving, the follow-up can carry that context into a conversation with Jed.

That gives the next decision some history: what you did, what you saw afterwards and what you're still unsure about. It doesn't prove the treatment caused the change — weather, growth and the original diagnosis can all muddy that story. This flow is for personal lawn care; I'm not claiming every business job runs the same way.

Jed gets a bounded product list, not permission to improvise

I've spent time reading Australian product labels to build the catalogue that grounds Jed's product suggestions. The app selects label-backed catalogue information for supported turf and site conditions, and instructs Jed to keep named suggestions within that information.

It's a useful boundary, but I won't dress it up as a guarantee about an AI answer. Jed can be wrong. Catalogue coverage is limited, and the app doesn't enforce every condition on every label. Check the current Australian label for your actual product, turf and situation — the label is the authority.

Why the new Android calculator gives a batch recipe

The distinction behind the calculator change is this: a label instruction expressed against water tells you about the mixture. On its own, it doesn't tell you how much ground that mixture should cover.

If a calculator quietly fills that gap with an assumed carrier volume, it can produce an area-based answer that looks more certain than its inputs justify. I don't want a result screen hiding missing information.

So in the new Android build, selecting a water-only rate leads to a batch recipe. You enter the water for the batch; the calculator works from the label information you've supplied. That result can be copied or saved, but it can't be logged from there as a completed lawn treatment — mixing something isn't evidence you applied it to a particular patch of ground.

This change has been tested in the Android closed-testing build; delivery to existing Play users has not been verified. The current Web calculator still has the older carrier-volume and area-conversion path, so don't assume the batch-only boundary applies there.

Whatever screen you use, check your inputs against the label. A calculator can do arithmetic; it can't make an unsuitable product suitable or supply directions the label doesn't have.

The public tools don't need an account

There are five tools on the free tools page:

• Lawn area measurement — trace the lawn on a satellite map.
• Label rate calculator — scale the rate from your own label to your measured area.
• Sprayer calibration — work from measured sprayer output.
• NPK converter — convert between oxide and elemental nutrient notation.
• 12-month lawn care calendar — see general task types for your grass and climate.

These are standalone tools. The public label-rate calculator isn't the Android batch screen described above, and sprayer calibration isn't sprinkler calibration.

If you haven't measured the lawn yet, start with the free lawn area tool. It's a practical input to sort out before comparing bags, plans or watering estimates.

What it costs

LawnSuite has a free account tier. The current advertised paid options are below, in Australian dollars, checked on 20 September 2026 against the pricing page.

The annual column is the annual subscription price, not a year of monthly payments added up. The founding offer is currently advertised; check the signup page for availability and terms when you join.

If all you need is an area measurement or a bit of label arithmetic, the public tools may be enough. The reason to use the app is keeping the lawn's details, jobs and follow-up in one place, with the paid plans adding the watering and seasonal-program features described here.

I built LawnSuite and its FAO-56 water-balance engine, and run it on my own Ipswich lawn. I've spent three years learning Sir Walter on heavy clay, including the mistakes, and read APVMA labels to gate the app's product database. For any lawn product you use, the label is the authority.
