Full feature list

Everything in Spotter Tools Pro

Six categories. One app. Everything below ships in the current build — tap a deep-dive link for more on radar and alerts.

GPS & Beacon

Spotter Network Beacon

Transmit your position so the NWS and fellow spotters know where you are during severe weather.

  • Foreground & background beacon

    A persistent foreground service keeps the beacon alive even when the screen is off, with a status notification you can tap to return to the map.

  • Configurable upload interval

    Choose how often the app pushes your position to Spotter Network — balance accuracy against battery.

  • Auto-restart on boot

    Optional boot receiver brings the beacon back automatically after a device reboot so you never forget to turn it back on.

  • Encrypted credential storage

    Your Spotter Network application ID lives in encrypted device storage — never on a server we operate.

  • Battery optimization wizard

    Built-in, device-specific instructions for Samsung, Xiaomi, OnePlus, Pixel, and more — so the OS doesn't kill the beacon in the background.

Map & Layers

The Map

A Mapbox-rendered tactical view with every layer a spotter needs — toggle exactly what's on screen.

  • Active spotter markers

    See every other Spotter Network beacon on the map with callsigns, vehicle info, and status.

  • NWS warnings & watches

    Tornado, severe thunderstorm, flash flood, and fire warnings as full polygons — plus tornado / severe watch boxes.

  • SPC storm reports

    Today's SPC tornado, hail, and damaging-wind reports plotted in real time.

  • SPC mesoscale discussions

    Short-fuse SPC forecast areas (MCDs) overlaid as polygons with full discussion text on tap.

  • Convective outlooks

    Day 1 and Day 2 outlooks — Categorical, Tornado, Wind, and Hail — switchable from a single sheet.

  • METARs

    Live airport observations with selectable variables (temperature, dew point, wind, pressure, visibility) and unit pickers.

  • Map style picker

    Switch between basemap styles to match the conditions and your preference.

  • Mapbox location search

    Geocode addresses, towns, and landmarks to jump anywhere on the map instantly.

Radar

Single-Site & Composite Radar

Real, decoded NEXRAD Level 2 in your hand — plus a composite mosaic and a full animation transport.

  • NEXRAD Level 2 decoding

    Reflectivity (BR), Velocity (BV), and Correlation Coefficient (CC) products decoded directly from raw Level 2 data — no third-party tile server.

  • Composite radar mosaic

    CONUS-wide WMS composite for at-a-glance precipitation context, with selectable sources.

  • Full animation transport

    Play, pause, scrub, change loop speed, and pick frame count — same controls you'd expect from a desktop radar app.

  • Custom GR2Analyst-style color tables

    Sixteen built-in .pal palettes for BR, BV, and CC, plus drop-in import for your own .pal files.

  • Storm cell picker

    Tap any storm cell on the radar to see its identifier and attributes pulled from the radar product.

  • Per-site selection

    Pick the closest WSR-88D site automatically, or choose a specific site to focus on — useful when chasing the edge of coverage.

Alerts & Notifications

Smart Push Alerts

An on-device watch worker fires NWS warnings even when the app is closed — with the controls a chase op-center actually needs.

  • Background watch worker

    A foreground service watches the NWS alerts feed and posts notifications without needing a cloud account.

  • Custom watch zones

    Track your current location, a fixed home zone, custom counties / forecast zones, or any combination at once.

  • Filter modes (including Outbreak)

    Choose between standard severity filtering or 'Outbreak' mode for active multi-state events where you want broader coverage.

  • Event-type filters

    Per-event toggles for tornado warnings, severe thunderstorm warnings, flash flood, fire weather, and more.

  • Custom sound profile + DND override

    Bundled severe-alert tone or stock system sounds, with an option to bypass Do Not Disturb for the most critical events.

  • Full-screen Tornado Emergency takeover

    On Android 14+, opt-in alarm-style full-screen intent for Tornado Emergencies and PDS warnings — wakes the screen even when locked.

  • Custom flash colors

    Pick distinctive flash colors per alert tier so a tornado warning never looks like a flood advisory.

  • Significant report & MCD pings

    Optional notifications when SPC posts a new mesoscale discussion or a high-tier storm report lands inside your zones.

Reporting

Severe Weather Reporting

File reports straight from the field — directly to Spotter Network, with the right metadata baked in.

  • All Spotter Network report types

    Tornado, funnel cloud, wall cloud, hail, damaging wind, flooding, and damage — each with the right structured fields.

  • Photo attachments

    Attach photos from the camera or gallery so your report carries verifiable visual evidence.

  • Reporting guidelines

    Built-in reporting guidelines reference so you can submit a clean report under pressure.

  • Local report history

    Every report is saved to a local SQLite database for your own records — even when offline.

  • Browse SPC reports on the map

    Toggle today's SPC tornado / hail / wind reports as map markers and tap any of them for full detail.

Customization & Setup

Set It Up the Way You Like

Spotter Tools Pro is opinionated about defaults but gives you control over the things that matter.

  • Guided onboarding

    A four-step setup walks you through permissions, map data, and the beacon so you're operational the first time you open it.

  • Searchable settings

    A sticky search field at the top of Settings filters every control on the page — find a toggle in seconds.

  • Connection status indicator

    An always-visible chip on the map shows whether you're online, on cellular, or offline.

  • Active spotter info sheets

    Tap any active spotter to see their callsign, vehicle, and last update without leaving the map.

  • No accounts, no analytics

    Nothing you do is sent to a server we operate. Beacon goes to Spotter Network, weather data comes from NWS / SPC / Mapbox — that's it.
