GDDTracker

Time lawn care perfectly with GDD Tracker. Get local weather, smart forecasts, and reminders so you apply treatments at the right time—without the guesswork.

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. No data selling. Location is used only to fetch local weather. iCloud sync is optional.

How it works:

1. Add your lawn and choose your grass type or set a custom threshold.
2. Set your start date (e.g., last application).
3. Track daily progress as GDD accumulates.
4. Log applications and get notified when it's time to reapply.

Perfect for: • Homeowners aiming for a healthier, weed-free lawn • DIY lawn enthusiasts who want precision timing • Lawn care pros who manage multiple properties and schedules
