Meshgrid is a peer-to-peer mesh networking app for iOS that enables off-grid maps, chat, and team coordination via Bluetooth Low Energy, without cellular service. It targets search-and-rescue, field crews, and disaster response teams with features like BLE node connections, GPS tracking, mesh messaging, and offline map layers. Its niche approach to reliable off-grid communication fills a known gap for outdoor and emergency coordination.

Target audience: field crews, search and rescue teams, disaster response coordinators, security and event organizers
