Collin Co Sheriff vs ZoneMap

The Colin Co Sheriff app provides citizens the ability to submit anonymous tips to the Collin County, TX Sheriff's Office. The app also displays agency crime alerts, online crime map, and other organization web and social media content.

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.
