RainHUD

Track approaching storms in augmented reality with a first-of-its-kind community reporting network.

Look up, not down!

RainHUD turns your iPhone camera into a weather instrument. Volumetric NEXRAD radar renders precipitation cores in 3D against the real sky — so that dark edge to the west stops being a mystery. Point your phone at it and see what it's tied to, how tall it is, and when it arrives.

TAP ANY STORM CORE Every core is a selectable target. One tap shows intensity (dBZ), altitude, bearing, distance, motion, ETA, data source, and confidence — with changes highlighted since you last looked. And the tracking is honest: when sources disagree or data goes stale, projected paths fade instead of pretending.

WARNINGS YOU CAN'T MISS Official NWS warning polygons, hail-prone cores, and tornado markers stand out as clear AR cues, placed beside the radar and cloud layers so high-impact information is obvious at a glance.

SCRUB THE TIMELINE Slide from past radar through Now into the forecast. Free includes 18 hours of NOAA HRRR forecast frames rendered on your device. Pro sharpens that to a 90-minute nowcast in 5-minute steps, 30-minute steps out to 18 hours, and an hourly tail to 48 — plus a 14-day daily forecast for everyone.

FIELD ALERTS WHILE YOUR PHONE IS DOWN Optional notifications surface NWS warnings and storm cores moving toward you between checks. An on-device barometric model can even flag "rain likely in the next hour" — no signal required. Built for people who work, play, and shoot outdoors.

LAYERS FOR THE WHOLE SKY Radar, storm tracks, satellite clouds, lightning, wind, and ground truth — official NWS spotter reports alongside community observations. Capture a 15-second Storm Clip of your AR view and share it anywhere.

A HEADING YOU CAN TRUST The compass reads your device's heading sensor only — AR tracking stabilizes placement but never rewrites your heading. The overlay recovers cleanly as you move and always shows its alignment status.

FREE AND PRO The core AR radar experience, NWS alerts, community reports, and the 18-hour forecast are free. RainHUD Pro adds Super-Res NEXRAD Level II volumetric detail, satellite and spotter layers, extended timelines, global location search, and advanced storm-approach notifications.

Built on NOAA NEXRAD Level II, MRMS, HRRR, GOES, NBM v5, RainViewer, and National Weather Service data.

RainHUD™ provides weather context only and is not an emergency alert system, certified weather instrument, or a replacement for official warnings. Always follow Wireless Emergency Alerts, NWS warnings, and local instructions.
