Your lawn.
This week.
Handled.
A lawn plan built for your grass, your ZIP code and this week's weather — and product picks from every major brand, not just one. No account. No fertilizer box you didn't ask for.

What you get

How it works
Tell it about your lawn. It tells you what to do.
Your ZIP + your grass
Ten US grasses, from Kentucky bluegrass and tall fescue to bermuda, zoysia, St. Augustine and centipede. Eight US climate zones, set from your ZIP code.
Pick your effort

Why it's different
The honest broker.
Most lawn apps are run by a fertilizer company, so they recommend their own bags. Others won't recommend a product at all. Lawn Obsessed picks the best product for your lawn and your budget from every major brand — and shows you why.
"The best product for the job wins. Not the one that pays us most."
Some product links earn us a small commission. That's how the app stays free — here's how it works.
- Every recommendation has a "Why?" with the actual numbers
- Built on university extension research, not forum folklore
- Your data stays on your phone — no account, no tracking
- Journal, progress photos, multiple lawns, dose calculator
- Event prep: peak your lawn for July 4th, the Masters, or the mother-in-law
- Robot mower? It knows — and tells you when to park it
Three ways to play
Choose your level of obsession.
God Mode
The whole street knows. HOA fears me. The full program: feeding, iron, pre-emergent, PGR, fungicide on schedule — and our Go For Gold pro-grade picks.
Dialed In
The neighbor gives a silent nod in acknowledgment when passing. The solid core: proper feeds, weed control, the right mowing height.
Keeping the HOA Off My Back
Green enough. No letters. Done. The minimum that actually works.
