ZoneMap vs TrailBand

Ditch the messy folded PDFs, tiny spreadsheet cells, and coffee-stained channel sheets. ZoneMap is a fast, offline-first radio reference, tactical mapping, and field comms toolkit built for first responders, wildland fire personnel, incident comms technicians (COMT/COML), ham radio operators, and scanner hobbyists. Keep your plans organized, searchable, and rock-solid—from the staging area to the backcountry dead zones. ZERO CELL SERVICE? NO PROBLEM Incidents rarely happen next to a cell tower. ZoneMap is 100% offline-first. Your entire channel directory, tactical maps, and RF toolset load instantly with zero latency—no loading spinners, no timeouts, and zero dependence on cellular data. HIGH-STRESS CHANNEL READABILITY Stop squinting at 8-point font in the dark. • Crystal-Clear Lineups: View channel numbers, band, digital modes (P25, DMR, mixed), frequencies, tones (CTCSS/DCS/NAC), power levels, and operational notes on clean, color-coded cards. • Scan Lists & Favorites: Star critical tactical nets or local repeaters for quick one-tap monitoring. • Automated ICS Imports: Parse ICS-204 and ICS-205 documents directly into live, interactive channel zones. TACTICAL MAPS, GEOPDF & GPS Turn your device into a full offline tactical GIS viewer: • GeoPDF Support: Import georeferenced maps from CalTopo, Avenza, Gaia GPS, or OnX. Run them as custom basemaps or layered overlays. Use the on-map fine-tuning tool to nudge or stretch GeoPDF boundaries to match live GPS. • Vector Layers: Drop in KML, KMZ, GPX tracks, and GeoJSON overlays with zero network overhead. • Universal Coordinate Converter: Instantly convert coordinates between DD, DMM, DMS, UTM, USNG, MGRS, Maidenhead Grid, Plus Codes, and GARS. BUILT-IN FIELD & RF TOOLKIT Leave the reference binders and cheat sheets behind: • Incident Forms: Fill, sign, and export official-layout ICS-214 Unit Logs and ICS-213 General Messages straight to PDF. • Fire Weather: Sling psychrometer Relative Humidity (RH) and Dew Point calculator with real-time hazard ratings. • Ham & RF Calculators: Antenna wire cut lengths (dipoles, EFHW, J-pole), VSWR & return loss, coax loss, dBm/watt conversions, OET 65 RF exposure distances, battery run-time budgets, and intermod product checks. • Tone & Audio Suite: Interactive DTMF keypad with playback, Morse code audio trainer (with Farnsworth timing), two-tone sequential paging alerts, and CTCSS/DCS reference lists. • Live Lookups: Satellite pass tracking with Doppler curves, solar weather band conditions, and callsign lookups (cached for offline field use). AGENCY & TEAM DEPLOYMENT Managing comms for mutual-aid strike teams or larger incidents? • Instant QR & Link Setup: Field crews scan a single QR code to download official lineups and incident forms instantly. • Multi-Agency Support: Connect up to 4 agencies simultaneously without numbering conflicts. • Free for Field Responders: Field operators access official agency plans, incident overlays, and custom agency forms completely free via simple Access Codes—no personal subscription required. Get your comms organized. Download ZoneMap today. Note: Advanced individual features and personal cloud sync require a ZoneMap subscription. Field users connecting via agency access codes do not require a subscription. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

TrailBand turns an FRS, GMRS or MURS channel number into the exact frequency and settings to program into a handheld radio. Built for offroad and overland groups, where some vehicles have bubble-pack FRS walkie-talkies and others have programmable radios, and nobody can work out how to make them talk to each other. • All 35 channels: FRS/GMRS 1 to 22, the eight GMRS repeater pairs, and MURS 1 to 5 • Receive and transmit frequency, offset, bandwidth, tuning step and power setting for every channel • CTCSS tones and DCS codes, with the bubble-pack privacy code number shown beside every standard tone • Search by channel number, or by a frequency you heard • Favorites for the channels your group runs • Export a CHIRP-compatible CSV to program a radio over USB • Send a plain text programming card to the group so every radio ends up identical • Reference articles on FRS vs GMRS, MURS, matching consumer radios, using a repeater, and choosing a trail channel Frequencies and power limits follow the US FCC allocations in 47 CFR Part 95. TrailBand is a reference tool: no account, no data collected, works entirely offline. A radio must be certified for the service it transmits in. TrailBand says plainly where the popular Part 90 handhelds stand.
