Hey Product Hunt! 👋 I'm Markus, a solo developer from Austria.

The Origin Story: Two years ago, I completely burned my front lawn. I bought premium fertilizer, followed a popular YouTube tutorial, and torched the grass. Why? Because the advice was meant for Texas, and a heatwave hit my area in Europe two days later.

The hard lesson: Lawn care is hyper-local. Timing, soil temperature, and real-time weather dictate everything. What works 5,000 miles away might ruin your yard.

I got so frustrated with generic guides and expensive, ad-filled tracking apps that I built LawnCoach.

💡 How it works: It's basically a professional greenkeeper in your pocket. You input your location (supports 20+ countries) and grass type, and LawnCoach generates a dynamic calendar that adapts to your local real-time weather.

⚙️ Key Features:

🌡️ Weather Guards: It literally throws a push warning and reschedules tasks if a heatwave or frost is approaching.
🤖 AI Coach (Gemini): Ask "Why are there yellow patches after fertilizing?" and get context-aware answers trained on pro-greenkeeper data.
⛳ Pro-Grade: Recommends the exact routines and active ingredients used on golf courses, not just big-box store marketing fluff.

💸 Why is it 100% Free? No ads, no paywalls, no subscriptions. I built this in React Native/Expo to scratch my own itch, and I just want people to use it and stop killing their grass. (Currently iOS only, Android is in the works!)

My ask to the PH Community: Please try the AI Coach! Throw your hardest, most specific gardening questions at it and let me know if it hallucinates or gives solid advice. I'd love your feedback on the UX! 🌱
