Comparison
YardLedger vs Sunday
A subscription lawn-care service that mails seasonal boxes of liquid nutrient pouches you spray through a hose attachment, with the plan built from a mailed-in soil test plus climate and topography data for your address — now fronted by a free app whose AI companion, Sunny, answers yard questions without a subscription. YardLedger is a lawn care record that turns your own history, your grass type, and NOAA, Open-Meteo, and USDA data into a schedule — and asks you to approve every task the AI proposes before it lands on it.
What using YardLedger actually looks like
YardLedger’s workflows do not change with who we are being compared against. Each one says the plan it runs on, and what a paid plan adds to it. For what each plan costs, see the pricing page.
Write down what you put on the lawn, while you are still standing in it
FreeMows, waterings, aerations, soil tests, notes and problem spots all go in against the yard they happened to, with the date and photos — and an application carries what it actually was: the product out of your Garage and the rate you put down. 16 record types, unlimited entries, on the free tier too. This is the part everything else reads from — there is no separate "data entry" step, because the log IS the product.
- Plus adds Multiple Properties: a second yard on Plus and up to 10 on Pro, each with its own history, zones and schedule.
- Plus adds photo storage: room for 100 photos on Plus and 500 on Pro, against 30 on the free tier.
Start with a plan on day one, before you have any history at all
FreeName a grass the engine models and setting the yard up puts a starter schedule on the calendar straight away — built by the same rules-based engine behind the free public schedule generator, from that grass, your USDA hardiness zone, the date you start and how hands-on you want to be. No AI wrote it, every item is visible, and you can move or delete any of them. A mixed or unidentified lawn skips the starter plan and starts from the assistant instead. Your soil and your weather come in after that, through the watering balance and anything you ask.
- Plus adds Calendar Sync: an iCal subscription, so the schedule shows up in Google Calendar, Outlook or whatever you already keep.
Ask about your own yard, then decide what lands on the calendar
FreeAsk the assistant a question or hand it a photo of a bad patch, and it answers against that yard's own history, weather and products — proposing tasks with the reasoning attached and safety notes on any plan it builds. It proposes; you add the tasks you want, one at a time or all at once, and anything you leave alone never reaches your calendar. The monthly credit allowance is what scales with the plan: 5 a month on the free tier (15 in your first), 150 on Plus, 600 on Pro.
Draw the yard into zones, and water off a running balance rather than a weekly habit
FreeTrace the lawn on an overhead view and each zone carries its own area, grass and exposure into one running balance for the yard: Open-Meteo evapotranspiration draws it down, rainfall credits it back — the modeled figure, raised to a NOAA gauge reading where one covers you — and the soil sets how deep and how often to refill — the USDA SSURGO estimate for your coordinates where the survey covers you, a loam default where it does not. What comes back out is per zone: how long to run each one. Free accounts get the whole engine, the automatic soil resolution and a property-level override of it.
- Plus adds Sprinkler Calibration: per-zone head type, a precipitation rate measured from your own catch-cup run, root depth and slope, so a run-time estimate starts from your system's settings rather than a standard rate.
- Plus adds Weather Stations: a personal weather station (Ambient Weather, Ecowitt, Tempest, WeatherLink or Netatmo) driving your yard's conditions from readings taken at the property, and its ET too on the days the station reports enough sun, wind and humidity to compute one.
- Plus adds Sprinkler & Utility Map: pinning the sprinkler heads, valves, supply lines, drains and the main shut-off on the same overhead view, with photos and notes.
Be told about the weather that is going to cost you something
FreeFree accounts get the seasonal safety alerts — frost, winterize-now, spring irrigation startup, and the spring and fall pre-emergent windows — alongside the ordinary care reminders, on push or email.
- Plus adds Proactive Care Alerts: day-to-day weather-aware alerts that ride along with your daily reminder: when to water, when to skip for rain, spray-weather checks, and a weekly summary..
Turn on a guided program and let it bring its own steps
FreeWinterization, spring irrigation startup and yard leveling are free programs on every plan. Enable one and its steps join this yard's plan, for you to review and complete like anything else on it.
- Plus adds Premium Care Programs: crabgrass pre-emergent on soil-temperature timing and PGR on accumulated growing degree days, plus fall pre-emergent for winter weeds and grub prevention.
Time a reapplication by the weather instead of by the calendar
PlusPer-yard accrual from your local weather, so the timing moves with the season rather than the calendar: PGR sums growing degree days and reminds you when the reapplication interval comes due, and crabgrass pre-emergent watches a rolling soil temperature climbing toward the germination threshold and opens its window as it approaches.
- Pro adds Custom PGR Target: tuning that interval to this lawn — an exact GDD target, or one dialled in from your height of cut — instead of the standard fixed cadence.
Cost
Which one is cheaper?
Neither YardLedger nor Sunday is cleanly the cheaper one — they are not the same purchase. Sunday's money buys nutrient pouches delivered to your door and its total depends on your lawn size, your plan and whatever offer is running; YardLedger's buys software and ships you nothing, so you source product yourself. The one line that does compare directly is the free one: both apps are free to start, and YardLedger’s free tier has no expiry and no card.
- What the money buys
- YardLedgerSoftware, and only software. YardLedger sells no fertilizer, seed or chemicals and earns nothing on what you apply, so the subscription is the whole of what it bills you — product you buy wherever it is cheapest.
- SundayProduct. Seasonal boxes of liquid nutrient pouches, with the plan and the app there to time what ships.
- What it costs
- YardLedgerNothing at all on Keep Track: no card, no trial clock, 1 yard, and unlimited care logging. Stay Ahead and Every Yard are ordinary monthly-or-annual software subscriptions; the current figures are on the pricing page rather than frozen into this table.
- SundayThe app is free, and Sunny is free without a subscription. Beyond that, Sunday's own pages disagree about where a plan starts — its custom-plan page says “as low as $55” while its own Sunday-versus-Scotts comparison says a full-season plan “starts at $80” — so the honest answer is to get a quote for your yard rather than to pick one of a competitor’s two figures. Plans are sized by lawn area and bill as a recurring seasonal subscription you can update or cancel any time; what that buys is the nutrients, not the software.
- Free path
- YardLedgerFive tools with no signup and no card, including a schedule generator that renders a real month-by-month plan from your grass type and ZIP.
- SundayA real one: the app and its Sunny assistant answer yard questions with nothing bought, and you can upload a photo of the yard for it to answer against.
Put your own product bill in the YardLedger column before you compare — sourcing the same nutrients yourself is a real cost, not zero. What Sunday's price adds on top of the product is the sourcing, the formulation and the timing of the delivery, which is most of what people are buying from it.

When Sunday is the better choice
If what you actually want is for the right product to arrive at the door at the right time — no sourcing, no spreader calibration, no decision to make — Sunday is the better purchase, and YardLedger will never ship you anything. Sunday also formulates to published exclusions (no glyphosate, imidacloprid, bifenthrin, or trifluralin), so if low-toxicity inputs are the deciding factor it is doing something YardLedger does not: YardLedger records and times whatever product you choose, it does not curate the shelf for you. And its app is worth having on its own terms — Sunny answers yard questions for free, with nothing bought, and takes a photo of the yard to answer against.
Side by side
| YardLedger | Sunday | |
|---|---|---|
| What you're actually buying | Software, on a freemium plan. YardLedger sells no fertilizer, seed or chemicals and earns nothing on what you apply. Plans are built against the products already in your Garage, so a recommendation can name a store brand, a generic equivalent of a premium bag, or nothing at all when the lawn does not need feeding. | A product subscription. You are buying seasonal boxes of nutrients; the plan and the app exist to time what ships and to keep the boxes coming. |
| How a task gets scheduled | Every task arrives with the reason it is there, and nothing the assistant proposes is scheduled until you approve it. Follow the plan as it comes, or change it. | The plan is built for you before the first box ships and arrives as a My Plan checklist with application dates on it — the decisions it encodes were made upstream of you. |
| Where the data comes from | Named and linkable: NOAA National Weather Service, Open-Meteo, phzmapi.org for the USDA hardiness zone, and USDA SSURGO for soil. | Says its lawn engine combines topography and local climate data with the result of your personal soil sample; the upstream weather and soil services behind that are not named on the site. |
| Platforms | iOS, Android, and the web app — the same account on all three. | iOS and Android apps, with the account managed on the web. |
| Care logging | Unlimited care events on every tier, including the free one, across 16 record types, with photos. | Tracking, reminders, and weed and pest records come with an active subscription and follow the applications in your Sunday plan — built around the products Sunday ships rather than as a general record of everything done to the yard. |
| Pricing | A free tier that does not expire and needs no card: 1 yard, unlimited care logging, the personalized seasonal schedule, three guided care programs, and frost and winterize alerts. Stay Ahead adds the premium care programs, day-to-day weather alerts, calendar sync, GDD, and a second yard. Current prices are on the pricing page. | The app is free, and Sunny is free without a subscription. Beyond that, Sunday's own pages disagree about where a plan starts — its custom-plan page says “as low as $55” while its own Sunday-versus-Scotts comparison says a full-season plan “starts at $80” — so the honest answer is to get a quote for your yard rather than to pick one of a competitor’s two figures. Plans are sized by lawn area and bill as a recurring seasonal subscription you can update or cancel any time; what that buys is the nutrients, not the software. |
| Try it before an account | Five free tools with no signup, including a schedule generator that renders a real month-by-month plan from your grass type and ZIP. | A genuine free path: download the app and ask Sunny about your yard, or photograph a weed, with nothing bought. The plan, the timed reminders, and the boxes are the subscription. |

Common questions
Is YardLedger a replacement for Sunday?
YardLedger is not a replacement for Sunday — they are different purchases. Sunday sells you the fertilizer and mails it to you on a schedule. YardLedger sells no products at all; it keeps the record of your yard and turns it into a schedule you approve. If you like Sunday's boxes, the two run together: log each Sunday application as a care event and YardLedger builds around it.
Which is cheaper, YardLedger or Sunday?
YardLedger and Sunday are not directly comparable on price, and any page that says otherwise is comparing the wrong things. Sunday's price buys physical product delivered to you. YardLedger's price buys software, and you buy product separately from wherever you like — often cheaper, and always your choice. YardLedger's free tier costs nothing, does not expire, and needs no card.
Does YardLedger do a soil test?
YardLedger does not mail you a soil-test kit. It does read one: upload a soil-test report from any lab and YardLedger drafts structured results from it — pH, phosphorus, potassium and the other rows it can read — for you to check before they feed the guidance. Sunday includes its own soil test with the first box, tied to the products it then ships you.
Will YardLedger only recommend certain brands?
YardLedger does not limit its recommendations to certain brands. It earns nothing on what you apply, so there is no catalog for a recommendation to steer toward — including the recommendation to skip an application because your lawn does not need it this month. A product-subscription business cannot easily make that last call.
