SoilIQ - Soil Intelligence

SoilIQ — Soil Temperature & Planting Intelligence

The weather app knows what's happening in the sky. SoilIQ knows what's happening underground.

Seeds germinate in soil — not in air. In early spring, soil and air temperatures are regularly 10–20°F apart. Only one of them tells you when to plant. SoilIQ is built around that truth.

REAL-TIME SOIL TEMPERATURE — 3 DEPTHS
Surface, root zone, and deep — live readings updated continuously, forecasted 14 days out. Every depth that matters, every day of the season.

PLANTAI — 130+ CROPS
Not "after last frost." The actual planting window — calculated from your live soil data and 14-day forecast. "Plant tomatoes in 4 days when root zone hits 60°F." Corn, soybeans, peppers, turf, cover crops, and 120+ more.

FROST ALERTS THAT GIVE YOU TIME
Near frost, hard freeze, killing freeze — powered by Apple Weather. An early warning the moment an event is detected, plus a morning reminder the day before so you can act before it arrives.
