PeakForecast - Outdoor Weather

⛰️ City weather apps tell you the weather at the trailhead.
PeakCast tells you the weather at the summit.

■ Summit-based forecasts
・Search any city worldwide, or pick from 100 famous Korean mountains built in
・World-renowned forecasts, corrected for summit altitude
・Compare expected summit vs. trailhead temperature on one screen

■ Today's hiking & camping index
・A 0–100 score combining rain, wind, temperature, thunderstorms and fog, with a traffic light for each factor
・Thunderstorm risk or an active weather warning forces the score down to "Danger" — no matter how nice it looks
・Transparent scoring: every deduction is listed, so you see exactly why
・Camping index covers the night (6 PM – 9 AM next day): overnight low, tent condensation, wind
・🌌 "Great night for stargazing" badge (cloud cover + moonlight combined)

■ Safety warnings, worldwide
・Automatic warnings built from forecast data: strong wind, gusts, heavy rain, snow, cold snap, heat, UV, lightning and fog — available everywhere on Earth
・In Korea, official KMA weather warnings and Korea Forest Service forest-fire risk are shown as well

■ Forecast data made for the mountains
・Lightning probability — know the risky hours before you're on a ridge
・Fog (visibility), wind gusts and dew point (predicts tent condensation)
・Precipitation range (min–max) — decide whether your pack needs a rain cover
・Sunrise/sunset countdown, golden hour, moon phase

■ Air quality
・Korea: AirKorea PM2.5 / PM10 with CAI grade
・Everywhere else: nearest-station data via OpenAQ

■ The basics, done right
・Hourly (24 h) and daily forecasts, precipitation probability chart
・3 home-screen widgets (light/dark)
・Morning weather briefing and sunset reminder notifications
・Offline cache — the last forecast stays visible even when you lose signal on the trail
