Performance Racing Network vs Horizon Alert

The Performance Racing Network (PRN) is one of two NASCAR licensed multi-broadcast radio networks which markets, produces and distributes motorsports programming 365 days a year. PRN broadcasts 13 Monster Energy NASCAR Cup Series races, twelve NASCAR Nationwide Series events and produces "Fast Talk", "The Pit Reporters", "Garage Pass" and "zMAX Racing Country."

Horizon Alert tells you exactly when, where, and how to look up — and only when you can actually see something. A "Up Next" feed gathers every event visible from your location into one chronological list: rocket launches, ISS passes, meteor showers, eclipses, spacewalks, and more. Each one shows a live countdown and which direction to face. A "Nearby" map view centers on you with launch pads pinned on real satellite imagery and a visibility ring drawn at true geographic scale. Real visibility intelligence: • Cloud cover at launch time, fetched per location • Sun elevation, so daylight launches aren't dressed up as visible • Distance from the pad, calculated as a great-circle bearing Smart alerts you'll actually trust: • Choose your timings — 1 day, 12 hours, 2 hours, 30 minutes, 10 minutes, or T-zero • Notifications auto-cancel if conditions degrade • If the sky unexpectedly clears, you'll get a "conditions just cleared" alert ISS overhead passes: • Rise compass, peak altitude, set compass, brightness • All predicted from your location, with countdowns Built privacy-first: • No accounts, no analytics, no third-party tracking • Your location stays on your device • The only thing sent off your phone is a rounded latitude and longitude to fetch a cloud forecast for your general area A clean, dark-mode-native experience for anyone who wants to look up.
