I built a free USDA zone-aware lawn care app and just shipped a full v2.0 redesign — would love feedback from lawn people and/or devs
Hey r/webdev,
I've been working on a side project called LawnSmart — a free web app that gives you a monthly lawn care checklist tailored to your specific USDA hardiness zone and state.
The idea started because generic "mow in spring, fertilize in fall" advice doesn't really cut it when you're in Zone 4b dealing with a short growing season vs. someone in Zone 9a with bermudagrass year-round. So I built something that adapts the task list, timing, and alerts to where you actually live.
Just shipped v2.0 — a full ground-up redesign with:
- 📅 Monthly task checklists sorted by priority (Critical → High → Medium → Low)
- 🗺️ USDA zone + state customization (e.g. pre-emergent timing varies significantly by zone)
- 📊 Calendar view, yearly history, and monthly notes
- 📱 Mobile-first PWA (installable, works offline) + desktop layout
- 🛒 Seasonal product recommendations matched to your current tasks
It's completely free and works in the browser — no account needed, all data stays on your device.
I'd genuinely love feedback on two fronts:
🌱 Lawn care side: Is the task timing accurate for your zone? Anything missing, wrong, or that doesn't match your real-world experience? The zone data is my biggest area of uncertainty and real-world input from people who actually maintain lawns would be invaluable.
💻 Tech side: PWA feel, performance, UX — anything that feels off or could be cleaner?
Happy to answer questions about either. Thanks for taking a look!
