Know the grade
before you ride.

GradeCheck overlays real-time road grade percentages onto Apple Maps. No route planning. No activity tracking. Just the road ahead.

How it works

Three steps to know the road

01

Open the map

Browse any road on Apple Maps — a route you're planning, your neighborhood, or a climb across the state. Tap any segment.

02

See the grade

The grade percentage appears instantly. Flat roads are green. Steep climbs are red. Color-coded at every segment.

03

Decide with confidence

Know whether to shift gears before the hill hits. Know if your EV can make it. Know if that trail is accessible. Real data, right now.

The scale

What the colors mean

0–4% Flat Comfortable for everyone. Standard road grade.
4–7% Gentle Noticeable climb. Fine for casual cyclists.
7–12% Moderate Real effort. Sustained climbing — shift down early.
12–18% Steep Expert territory. Locals only.
18%+ Extreme Medical-grade climbing. Not for the faint-hearted.

EV drivers

Grade matters enormously for range. Plan routes with elevation data to get accurate distance estimates.

Outdoor adventurers

Hikers, trail runners, and gravel riders who need real grade data to plan access and safety.

Truck & RV drivers

Know the grade of mountain passes before committing. Plan safer descents with engine braking in mind.

Every road has a grade.
Now you know yours.
