New — a calendar for the whole season

Know when to water.
Or when not to.

Most lawns are watered on a timer, and timers don't know it rained. Lawn Logic watches the weather at your address, tracks the moisture your soil is actually holding, and gives you one clear answer each morning.

Free, no ads, no account needed to look around. Pro from $2.99/month.

Lawn Logic showing a soil moisture arc at 29 percent, labelled Thirsty, with the recommendation to water for 30 minutes.

It's a model, not a schedule

Three things most watering apps get wrong.

🌧️

It counts the rain

Every day, Lawn Logic subtracts what actually fell from what your lawn needed. If a storm covered you, it says so and tells you to skip.

🌱

It tells you to wait

Letting soil dry toward its trigger is what drives roots deeper. Half the time the honest answer is "not yet" — so that's what you get.

📍

It knows your lawn

Bermuda in sand is a different lawn from fescue in clay. Grass type, soil, shade, and mowing day all change the answer.

Watering was only half the job

New in 1.7 — a calendar for everything else your lawn needs.

🗓️

It knows the season

Fescue is fed in autumn and rested in summer. Bermuda is the exact opposite. Same month, different advice — because getting that backwards is how lawns get damaged.

📋

It tells you how

Not just "aerate in September". Rent the machine rather than buy it, water the day before, two passes at right angles — and roughly 30 lb of seed for a typical lawn.

Builds the season around your grass, soil and location, sequences the work in the right order, and gives you the reason for every date.
