Get tonight's meteor shower forecast in one screen — radiant altitude, moonlight interference, cloud cover, activity. IAU-verified peak times.
Will there be a meteor shower tonight — and can you actually see it?
MeteorCast answers in one screen. A single Tonight card gives you a Good / Maybe / Poor verdict and a 0–100 score, computed on your device from four honest inputs: which meteor shower is active tonight (by IAU rate), how high its radiant sits above your horizon, how much the Moon will wash out faint meteors, and how thick your local cloud cover is. No paywalls hiding the answer. No paragraphs to read to find out.
Behind the verdict are four expandable reasons you can inspect at a glance:
• Shower activity — which shower is peaking tonight, its Zenithal Hourly Rate ceiling, and whether tonight sits inside its active window (Perseids, Geminids, Quadrantids, Leonids, Lyrids, Orionids, Eta Aquariids, Taurids, and other major showers from an embedded IAU/AMS reference).
• Radiant altitude — the radiant's current altitude above your horizon, computed from J2000 equatorial coordinates and your observation spot's latitude. A radiant near the horizon means fewer meteors; a high radiant means many.
• Moonlight interference — an interference index built from moon phase and current moon altitude. A near-full moon high in the sky can hide most meteors even under a great forecast; MeteorCast tells you exactly how much.
• Cloud cover — cloud percentage and visibility from WeatherKit for your observation spot. Tri-state: if WeatherKit is unavailable, MeteorCast keeps the last verdict and clearly labels the missing factor rather than pretending.
KEY FEATURES
• Tonight Verdict — Good / Maybe / Poor + 0–100 score in one screen.
• Peak Window — 21:00 to 04:00 timeline showing when the radiant hits its highest altitude, overlaid with moonset. Locked to Premium.
• Observation Spots — save up to 10 favorite spots (backyard, cabin, remote dark-sky site) and switch between them instantly. Free tier: 1 spot.
• Embedded IAU/AMS Data — 14 major meteor showers with radiant coordinates and ZHR ceilings, offline. Updated with the app.
• WeatherKit + Location — cloud and visibility from Apple WeatherKit; precise location only used for tonight's forecast and your spots. Never uploaded.
• Tri-State Honesty — offline, permission denied, WeatherKit down — MeteorCast tells you what factor is missing instead of faking a verdict.
WHAT MeteorCast IS NOT
• Not a star map (no sky chart, no constellation view — try SkyCue for that).
• Not a meteor shower encyclopedia (just tonight, and just enough context).
• Not a long-range calendar (this week / this month deferred to v1.1).
• No AR, no camera, no social features, no ads, no subscription.
PRIVACY FIRST
Precise location is used only to compute tonight's forecast at your saved spots. It never leaves your device. Purchase history is tracked by Apple (as with any IAP) for entitlement — MeteorCast itself has no server. Nutrition label: Location + Purchases used only for App Functionality, linked to you per Apple's standard IAP model.
PAY ONCE, FORECAST FOREVER
Free tier gives you the Tonight Verdict, all four reasons, and 1 observation spot. A single Lifetime purchase of $3.99 unlocks the Peak Window preview (radiant altitude timeline + moonset overlay) and expands your spot library from 1 to 10. No subscription. No ads. One-time.
Built for the nights when you'd actually go outside.
