LoRa mesh SAR app with voice, maps, and live team tracking—works without cell towers.

Strengths
  • •Codec2 voice clips and AVIF image compression are tuned specifically for low-bandwidth LoRa links, not generic trade-offs.
  • •Live location, trails, and SAR incident markers give teams spatial context during active operations—not just chat.
  • •Cross-platform (iOS and Android) with offline maps and GPX import/export—genuinely field-ready today.
Weaknesses
  • •Requires LoRa hardware (not in scope, but user must source separately)—limits accessibility vs cellular mesh.
  • •No visible user reports or deployment case studies—unclear if SAR teams have actually adopted it.
