★ WEATHER RADAR: LEVEL 2, LEVEL III & TDWR
GPU-rendered radar, crisp at any zoom. NEXRAD Level 2 decoded on your device: Reflectivity, Velocity, Correlation Coefficient, Spectrum Width, and Storm-Relative Velocity, with elevation tilt selection. Plus Level III dual-pol (ZDR, CC, KDP, HCA), derived products (VIL, Digital Precip Rate, rotation), storm tracks, mesocyclone and TVS markers, VAD Wind Profile, and the 45-site TDWR network. Add a Mesoanalysis layer, Storm Cell Deep Dive, and dual-view compare. 16 .pal color tables, or import your own.

★ ANIMATED & COMPOSITE RADAR
Loop recent volumes (play, scrub, speed). Pair with a GPU-crisp CONUS MRMS mosaic from the full catalog, including the FLASH flash-flood suite, with 12-hour playback and tap-to-read values.

★ SEVERE WEATHER ALERTS
Background NWS warnings with a polygon preview map, even when the app is closed. Filter modes: Standard, Outbreak, and PDS/Emergency only. Watch zones: current location, home, any city, state, or nationwide. Severe alert tone, Do Not Disturb override, and an optional full-screen alarm for Tornado Emergency and PDS warnings (Android 14+, off by default). Each warning shows estimated population inside the polygon.

★ NWS & SPC ON THE MAP
• 50+ NWS warning polygons, individually toggleable
• Tornado and severe thunderstorm watch boxes
• SPC Mesoscale Discussions and WPC flood discussions, full text on tap
• Outlooks: convective Day 1 to 8, thunderstorm, excessive rainfall, fire weather, winter storm severity, CPC 6 to 10 day, drought
• SPC storm reports and the live Spotter Network feed

★ LIGHTNING, SATELLITE & TROPICAL
Live GOES GLM lightning. GOES East and West satellite (Infrared, Water Vapor, Visible, GeoColor) with a radar-synced cloud loop. Worldwide tropical and hurricane tracking: outlook areas, forecast cones, spaghetti models, and wind arrival times.

★ WEATHER MODELS & FORECASTS
Overlay HRRR, GFS, RRFS, NAM, and ECMWF forecast guidance (reflectivity, temperature, wind, CAPE, precipitation) with a time bar and legend.

★ WIND, SOUNDINGS & OBSERVATIONS
Animated surface wind flow with speed-colored particles. On-device skew-T soundings and hodographs, tap anywhere for a profile. Plus RTMA observations, MRMS observed precipitation, METARs, EPA AirNow air quality, and WPC surface fronts.

★ LIVE CHASERS & CAMERAS
Watch major storm chasers stream live via YouTube and Facebook Live, right on the map. Plus tens of thousands of DOT traffic cameras across 37 states, FAA, Windy, NOAA buoy, USGS volcano, National Park, and ALERTWildfire. Live video where offered.

★ SPOTTER NETWORK REPORTING
Tornado, funnel cloud, wall cloud, hail, wind, flood, and damage reports with the exact fields Spotter Network expects. Reports queue offline and auto-upload.

★ GPS BEACON & CHASER MODE
Foreground and background beacon to Spotter Network. Configurable interval, encrypted credentials, auto-restart on boot. Chaser Mode orients the map to your heading.

★ FIELD TOOLS
City search, long-press map menu, storm cell picker, distance and bearing tools, freehand drawing, storm track projection, per-event colors, county and state lines, and 6 themes including true-black OLED.

★ BUILT FOR SEVERE WEATHER SEASON
Tornado outbreaks, supercells, hail, damaging wind, flash flooding, winter storms, and hurricane landfall. Whether you chase, spot, or just watch the sky from home, Spotter Tools Pro puts professional weather radar and real-time NWS alerts in your pocket.

Ratings and reviews

One of the most effective all-in-one storm-chasing tools available. I love that you only have to pay once. You keep receiving upgrades. Have used other apps, but you'll need to use multiple apps to get all of the information you need for storm chasing and forecasting. With this app, everything is in one place and at your fingertips.

Well they added everything I could think about, the app is definitely professional and contends with the other professional apps out there! The developer has definitely put the time into making this app a perfect radar app for anyone and experienced chasers and not only keeps building on it I definitely highly recommend this radar app and would give more stars if I could!

Best all-in-one storm spotting/chasing app on the play store. I can't recommend this app enough.

What’s new

INSTANT LEVEL 2, NOW SIX PRODUCTS
Correlation coefficient, spectrum width, storm relative velocity and normalized rotation join reflectivity and velocity on the fast path. Switching products is quick now too.

NORMALIZED ROTATION WORKS
It never drew anything before. It does now.

TROPICAL FIX
A Category 4 hurricane south of Hawaii drew nothing. Storms crossing 140W now render, and East Pacific recon tracks parse.

Plus much clearer exported loops and wider Pacific satellite coverage.
