GDD Tracker is the complete lawn care companion for homeowners and pros who want precision timing and organized records. Using your location and hyper-local weather data, the app calculates Growing Degree Days (GDD) so you know exactly when to apply pre-emergents, post-emergents, plant growth regulators, fertilizers, and more. But GDD Tracker goes beyond just tracking — it's a full-featured lawn management tool. GDD Tracking & Forecasting • Accurate GDD calculations based on your location and daily temps • Forecasted date to hit your target threshold • Clear progress with percentage, badge, and cumulative/daily charts • No-spray advisories for high wind, heat, or rain Application Log • Log every application — PGR, fertilizer, weed control, fungicide, insecticide, and more • Track products, rates, and notes for each entry • View season history with year-over-year comparisons • Export your records as CSV or PDF Smart Reminders • Get notified when it's time to reapply • Set reminders by GDD accumulation, calendar days, or soil temperature • Early warning alerts as you approach your threshold Built for Your Lawn • 50+ grass variety profiles — Bermuda, Zoysia, Fescue, Bluegrass, and more • Rate calculator for exact product amounts based on lawn size • Soil temperature estimates for pre-emergent and seeding timing • Manage multiple lawns with separate locations, settings, and color tags Everywhere You Need It • Widgets for your Home Screen • Apple Watch app for a quick glance • iCloud sync across all your devices • Optional device location or locked "home" coordinates Privacy-First No ads.
