GrowCalc — Precision Lawn Care in Your Pocket

GrowCalc is the complete agronomic toolkit for lawn enthusiasts, homeowners, and turf professionals. Built on precision math and backed by live climate data, it removes the guesswork from every application so you can grow a healthier lawn with confidence — anywhere in the world.

PRECISION NPK CALCULATOR: Calculate exact N-P-K rates per 1,000 sq ft (or 100 m²) for any product. Full support for granular, liquid, and ready-to-spray (RTS) formulations, with density, coverage, and dilution math handled automatically. Tank-mix multiple products in a single "cocktail" and see nutrient totals for the entire mix at a glance.

SMART APPLICATION LOG: Log every fertilizer, herbicide, fungicide, insecticide, and plant growth regulator applied to your property. Track season totals per zone, monitor cumulative NPK, and export complete records for review or record-keeping.

AI PHOTO DIAGNOSIS: Snap a photo of any weed, disease, insect damage, or nutrient deficiency and receive an instant identification with a step-by-step treatment plan — powered by advanced AI trained on turf science.

AI LAWN ASSISTANT: Ask any lawn-care question and get expert-grade answers on demand. From product substitutions to timing questions, your personal agronomy advisor is always one tap away.

LIVE WEATHER & SPRAY WINDOWS: Hyperlocal forecasts, hourly conditions, and soil data driven by your GPS location. Color-coded Spray Windows show whether the next seven days are Excellent, Good, Fair, or Poor for application — with clear "why" reasoning based on wind, rain, and temperature.

GROWING DEGREE DAYS (GDD): Track live Growing Degree Days for your climate to time PGR reapplications, fungicide intervals, pre-emergent windows, and pest activity. Automatic reminders fire when it's time to reapply.

BIO WATCH — GLOBAL PEST & DISEASE PRESSURE: Real-time pest, fungus, and disease pressure indicators for any location worldwide. Stay ahead of pressure spikes before they cost you a summer.

SEASONAL AGRONOMIC CALENDARS: Month-by-month task schedules tuned to warm-season and cool-season grasses — covering fertilization, aeration, dethatching, pre-emergent timing, seeding, and more.

PRODUCT LIBRARY & DASHBOARD: Save your go-to products with full labeled specs (NPK, active ingredients, coverage, application rates). Season-at-a-glance dashboard summarizes nutrients delivered, treatments logged, and upcoming reminders across every zone.

WARRANTY & EQUIPMENT KEEPER: Store equipment receipts, maintenance history, and warranty expiration dates in one secure vault — with expiry countdowns so you never miss a claim window.

MULTI-ZONE PROPERTY MANAGEMENT: Track front, back, side, and specialty areas independently. Perfect for enthusiasts, property owners, and pros managing multiple lawns.

METRIC & IMPERIAL, WORLDWIDE: Every calculation, weather feed, and biological tracker works globally. Full dynamic unit conversion throughout the app — no matter where you live or what units you prefer.
