AvWx vs ARTstronomy Planner

Situational awareness for pilots and dispatchers — every airport you care about, on one screen. AvWx brings NOAA's forecasts and radar, AviationWeather.gov, FAA advisories and NOTAMs, Digital ATIS, NWS alerts and Apple Weather into one picture, so you can read a whole day of flying without opening five apps. TAF TIMELINE Every TAF drawn on one time axis: TEMPO and PROB groups in their own band, each hour's worst ceiling and visibility with its flight category, runway wind components, the current METAR overlaid, and NOAA's hourly forecast beneath it. NOAA METEOGRAM One day, hour by hour: clouds by altitude to 45,000 ft, the freezing level, precipitation and snowfall by type, winds aloft and the flight category — each reading labeled with the NOAA model behind it. MAPS AND RADAR NOAA's newest radar scans looped over the last hour, storm cells with motion arrows, lightning within minutes of the flash, satellite clouds, fronts, NWS alert regions, worldwide forecast layers, airspace, and satellite imagery down to the runway. ALSO • Ceiling and visibility every 15 minutes for six hours in the US, and out to a week worldwide • NOTAMs worldwide, straight from the FAA's NOTAM Management Service — closed runways and approach aids out of service marked on the runway table and METAR tiles, closures drawn on the satellite view • Traffic flow and the runways in use, handy at non-towered fields • SIGMETs, CWAs and NWS alerts matched to your airport's position, not just its region • Decoded D-ATIS, METAR tiles, favored runways, density altitude, sun and moon • Saved places beyond airports — home, layovers, anywhere — with full forecasts FREE: up to five airports, METAR and TAF, the TAF timeline, NOTAMs, traffic flow and FAA advisories. PREMIUM: unlimited airports, the maps and radar, the NOAA meteogram and charts, Apple Weather's tiles and charts, and no ads. One-week free trial. An in-app Guide and Legend explain every bar and color. AvWx is a professional supplement, not a replacement for certified flight-planning tools.

One honest GO/MAYBE/NO GO verdict for tonight's sky — tuned to what you're shooting. ARTstronomy Planner tells you — honestly — whether tonight is worth setting up the telescope or driving out to your dark site. No more juggling five weather apps, squinting at cloud maps, and guessing when the moon's too bright to bother. Pick what you're shooting — deep-sky, Moon & planets, or a mixed night out — and get one clear verdict: GO, MAYBE, or NO GO. WHAT YOU GET • Smart verdicts, tuned to your session — cloud cover, moon brightness, seeing, sky darkness, and dark-window length are weighed differently for long-exposure imaging than for a casual night at the eyepiece. • Sky Timeline — an hourly, color-coded forecast strip you slide through like a dial. Total cloud, seeing, precipitation, and humidity for the next two weeks, with sunset, sunrise, and astronomical twilight marked right on the grid. • Live moon phase — a real moon-phase icon and illumination percentage that updates as you drag through time, so you can see exactly how the moon will look at 11pm versus 3am. • ISS pass tracking — visible International Space Station passes appear right on your timeline. Tap one for rise, peak, and set times, direction, altitude, and estimated brightness. • Narrowband-aware scoring — tell it you shoot narrowband, and the app stops marking down nights for a bright moon your filters can cut right through. • Drive-out comparison — see at a glance whether your dark site is actually worth the drive tonight, or if home is just as good. • Bortle sky-quality estimates for any site, home or away, pulled from real light-pollution data. • Ranked target suggestions — the best deep-sky objects or Moon/planet targets for tonight, scored for your gear and your sky. ARTSTRONOMY PLANNER PRO Free, forever: • Tonight's GO / MAYBE / NO GO verdict for your location, for deep-sky, Moon & planets, or mixed sessions • Score and "why" breakdown, live moon phase, and Bortle estimate for your location • Sky Timeline for the next 24 hours Pro unlocks: • The full 14-day hourly Sky Timeline • Drive-out comparison with your saved dark sites • Ranked target suggestions for any night • ISS pass tracking • Narrowband-aware scoring Try Pro free for 7 days.
