Wake Watch is the Boater's Resource for information on no wake zones, boating speed limits and bridges. We have no wake zone and boating speed limit maps for FL, NC & CT. We have bridge heights and opening schedules for FL, GA, SC, NC, VA & CT. The app uses your GPS location to track your boat on the map to keep you aware of what bridges and no wake zones are coming up on your route. NOAA boating charts can also be used as the base map! This is a must have for recreational boaters in Florida and snowbirds cruising south for the winter down the ICW. Boating in FL can be frustrating due to no wake zones and limited bridge openings. Limited bridge openings could mean waits of up to an hour or more. This tool will help you to stay informed and plan accordingly. The app covers all of the waterways in Florida, including the Intracoastal Waterway (ICW), bays, inlets and canals. Also covers key areas such as the Okeechobee Waterway, New River, and more. Includes information from a variety of sources, including NOAA charts, state and federal Manatee Protection Zones, Boating Safety Zones and more. It covers the ICW all the way up to Chesapeake Bay, and all coastal waters and rivers up through VA. Tide station information was also added. For each tide station, the times for high and low tides each day are shown. Tidal heights are included as well. NOAA Coastal Waters Forecasts are now included. These include wave height forecasts up to five days out. NOAA Raster Nautical Charts can also be used as the background maps. Speed and heading data are now included. If your primary GPS/plotter fails, you've got NOAA Charts, speed and heading...Everything you need!

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 Your first 14 days are free, with no card needed. After that, SENTINEL Pro is $9.99 a year. One subscription unlocks the full app on all your devices.

Terms of Use: https://strikeapps.github.io/sentinel-legal/terms.html Privacy Policy: https://strikeapps.github.io/sentinel-legal/privacy.html A NOTE ON SAFETY SENTINEL is a coordination tool that supports trained judgment — it is not a substitute for proper training, equipment, or agency procedures. 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.

Verdict
The clearest difference is price: SENTINEL TacMap at Free against WakeWatch's $1.99. SENTINEL TacMap also leads on rating (5.0 vs 2.2) and update cadence (every 4 days vs every 2 months). WakeWatch's advantage is in-app purchases (none vs 2) and ratings volume (10 vs 1). On ads and device support there is nothing between them.
