Sentinel is a mission planning, navigation, and team coordination platform for iPhone. Build the plan, run the mission, and keep every operator on the same picture — with end-to-end encrypted comms and live position sharing. MISSION PLANNING The math and products that normally cost you a laptop, a protractor, and time you don’t have: • Gridded Reference Graphic (GRG) generation over any structure or area • Line-of-sight and terrain masking analysis between any two points • Helicopter landing zone assessment — size, slope, and obstructions • MEDEVAC 9-Line builder with formatted, transmittable output • Range, bearing, and elevation profile between any two points NAVIGATION • MGRS • USGS topographic and imagery basemaps • Route legs with distance, bearing, and running time • Waypoint capture, edit, and bulk management ENCRYPTED TEAM COMMS Team chat secured end to end. Your traffic is unreadable to anyone outside your team, including us. Messages queue when a member drops out of coverage and deliver the moment they’re back. SATELLITE-READY Where your carrier delivers satellite data to apps (direct-to-cell on supported iPhones), SENTINEL detects the satellite link and switches to a low-bandwidth mode on its own — position reports and team messages keep moving, and map downloads wait for a full-strength connection. POSITION LOCATION INFORMATION Live PLI across the team on a shared map. See where everyone is, in real time, without a TOC, a laptop, or a tech in the truck. Set update intervals to balance fidelity against battery and bandwidth. SHARED DATA Drop it once and the whole team has it. Waypoints, hazards, rally points, objectives, and custom markers sync across every device on the mission — so the picture on your screen is the picture on theirs. • Shared waypoints and overlays with live sync • MBTiles and GeoPackage import for your own map products • Export mission data for after-action review and reporting WHO USES SENTINEL • Volunteer and county search & rescue teams • Emergency management and incident command • Law enforcement tactical and special operations units • Wildland fire and remote-area EMS • Backcountry hunters, overlanders, and expedition teams WORKS WITH YOUR ECOSYSTEM • Import and export KML/KMZ files and CoT data packages • Bundle markers, graphics, and ops data into packages and share them with your team in seconds • Runs on iPhone, iPad, and Mac with one subscription YOUR DATA STAYS YOURS • End-to-end encryption for team content — the server relays ciphertext it cannot read • No ads, no tracking, no selling data • Location sharing is opt-in, visible, and instantly revocable • Delete your account and its data in-app at any time SENTINEL PRO Start with a free 2-week trial, then choose $5.99/month or $29.99/year.

Always carry backup navigation and communication for life-safety operations. BUILT BY SOMEONE WHO USES IT Sentinel was built by a working operator tired of stitching together four apps, a laminated card, and a Sharpie to do one job. Every tool here exists because it was needed on an actual mission. PRIVACY Team communications are end-to-end encrypted. We can’t read your messages, your positions, or your mission data. No ad networks. No data brokers. No selling your location. ## Key features - Gridded Reference Graphic (GRG) generation - Line-of-sight and terrain masking analysis - Live position sharing with end-to-end encryption - MGRS navigation with topographic basemaps - Shared waypoints and overlays with live sync - Import/export KML/KMZ and CoT data ## Pricing and in-app purchases Base price: Free. **Subscriptions** | Subscription | Price | Period | | --- | --- | --- | | SENTINEL TacMap | $29.99 | per year | | SENTINEL TacMap | $5.99 | per month | ## Frequently asked questions about SENTINEL TacMap ### What is SENTINEL TacMap?
