Why cloud cover percentage isn't enough

What GoldCast Scores That Standard Apps Don't

Your iPhone's built-in weather app shows cloud cover as a single percentage. That number doesn't tell you cloud altitude, whether the horizon is clear, or how humidity will affect colour saturation. The variables that determine sunset quality are almost never shown in standard weather apps. GoldCast is built specifically around them.

☁️

Cloud Altitude, Not Just Coverage

40% low stratus kills a sunset. 40% mid-level altocumulus with a clear horizon produces vivid colour. GoldCast separates cloud by altitude layer and scores the combination that matters for sunset quality — not a single coverage number.

🌅

Horizon Clarity Score

A clear band near the western horizon is the single most important variable for dramatic sunset colour. GoldCast factors horizon clarity into every score — the variable most apps don't show at all.

💧

Humidity and Colour Saturation

High humidity mutes colour. Low humidity after a cold front produces the most vivid, saturated tones. GoldCast includes humidity in the quality score alongside cloud conditions.

🔔

Push Alerts Before It Happens

The most common problem is finding out a sunset was spectacular the next morning. GoldCast sends a push alert when tonight's score hits your threshold — before the window opens. Set it once, let it run. Exclusive to the iOS app.

🔔

Never Miss a Good Sunset Again

GoldCast monitors conditions daily for your saved locations. When an exceptional sunset is forecast, your iPhone notifies you before the window opens — not the morning after. Exclusive to the iOS app.

Common Questions

What is the best sunset app for iPhone?

LightCast GoldCast. It scores sunset quality using cloud altitude, horizon clarity, and humidity — not just cloud cover percentage — and sends a push alert when tonight looks exceptional. Free on web, push alerts in the iOS app. Download here. $2.99/month after a 7-day free trial.

Is GoldCast free?

The web version at lightcastsuite.com/goldcast is free. The iOS app includes a 7-day free trial then $2.99/month. Push alerts and saved locations are iOS-only.

What makes a good sunset forecast?

Broken mid-level cloud, a clear horizon band, and low humidity. GoldCast scores all three together into a single 0–100 quality score so you get a direct answer rather than interpreting multiple variables yourself.

Does GoldCast include golden hour timing?

Yes. GoldCast calculates the exact golden hour start and end for your location and date, plus blue hour timing. The quality score tells you whether that window will be worth being outside for.
