Lawnplan
A 12-month lawn calendar timed for your grass type — cool or warm season
Pick fescue/bluegrass or bermuda/zoysia and Lawnplan lays out every pre-emergent, fertilizer, overseed and aeration window with the reason behind the timing, counts the 16-week germination block before you seed, and logs the product and rate you used. Free, nothing to install.

What you can do in Lawnplan on the web
Real grass-type templates
The full cool-season and warm-season task sets from the iPhone app — 23 and 24 tasks across all 12 months, each with its timing guidance, not a placeholder list.
The pre-emergent vs overseed guard
Log a pre-emergent and the home screen counts down the 8–16 week germination block, naming the date seed will actually come up.
Product and rate log
Mark a task complete with the product, the application rate and a note; every completion builds a searchable history you can export as CSV.
Square-footage product calculator
Turn a bag rate like 3.5 lbs per 1,000 sq ft into pounds for your lawn and the number of bags to buy, with the leftover shown.
As many lawns as you have
Front, back and the rental each get their own grass type, square footage and 12-month plan — switch between them from the season plan.
Yours, in this browser
No account and no server: lawns, plans and history are saved locally and exportable as JSON or CSV whenever you want.

Questions
Is the web version of Lawnplan free?+
Yes. Sign in with a free All Things AI account and use every screen — no subscription, no in-app purchases.
Where is my data stored?+
Only in this browser's local storage. Nothing you enter is sent to our servers, so we can't see it, back it up, or restore it. Clearing site data, a private window, or another device starts empty. Export a backup from the in-app menu to keep it.
Do I need an account?+
You can read about the app without one, but you must sign in to open it. Sign-in is free and takes a few seconds with Google.
How is the web version different from the Lawnplan iPhone app?+
No push reminders on the web — the iPhone app can nudge you when a treatment window opens. Nothing reads live soil temperature or your local frost dates; the months come from the grass-type template and you adjust for your own climate. Guidance is informational lawn-care advice, not a product label — always follow the rate printed on the bag.
