MiraTrex PRO CHARTS™ is a powerful, yet easy-to-use marine navigation system. Whether you’re a fisherman, weekend cruiser, sailor, diver, jet-skier, or an offshore captain needing to find an exact location hundreds of miles offshore, PRO CHARTS™ will get you there and back home safely – with nothing more than your iPhone or iPad. Key Features: • High-resolution NOAA nautical chart coverage with depths for all U.S. coastal areas, the Great Lakes, major U.S. river systems, and Brazil plus global high-level nautical charts. Charts are automatically updated based on NOAA chart corrections. • Easy one-touch Waypoint and Route creation. Pre-plan your routes at home or create them at sea with equal ease. Just touch the screen to create new waypoints and routes. • Find your friends on the water. With our new Buddy-tracking feature, you can see and meet up with your friends while you’re out on the water. If you’re on your secret spot and don’t want to be seen, you can hide your location with the touch of a button. • Stay safe. Easily create and send a Float Plan of your trip to a friend or family member. Your Float Plan and location history can be forwarded to search and rescue personnel in case of an emergency. • Easy point-and-steer navigation. The red heading bug on the large on-screen compass always directs you to the next point on your route. Navigation is as easy as pointing your boat at the heading bug to stay on course. • No Network. No Problem. PRO CHARTS™ is designed so no internet connection is required to view your charts while out on the water. You simply download in advance any charts you’ll need at sea with the touch of a button. • Record your tracks. Track your position in real-time and later view your track history. • Fully indexed point of interest (POI) database including weather, aids to navigation (markers and lights), obstructions, tides, currents, your buddies, and more.

* What is Sea Drive? Sea Drive is a marine and boating navigation application focused on charting, navigation, route building, track recording, tides, currents, and more! Our goal is to provide the best user experience for boaters on and off the water. Sea Drive provides FREE US charts! We believe that everyone should have the tools on the water to feel safe and know how to find their way home (or pull up to a restaurant). * Who is it for? Sea Drive is for all of you who love the water! If you spend time on sailboats, fishing boats, bowriders, wakeboard boats, kayaks, or canoes this app will quickly become your go to co-captain * What are the features? **Offline Use Sea Drive is meant to be used on the water and in the real world, that means cell service won't always be available. Charting, tides, currents, routing, tracks, GPS, compass, and more are all available without internet! ** Free Chart Data (US) Currently only US charts are available (and will always remain free thanks to NOAA and your tax dollars). As Sea Drive improves we will be adding other chart regions for free or as low cost as possible. ** Tides and Currents Tap a tides or currents icons on the chart to view offline predictions (for years into the future) at over 3000 locations. ** Build and Navigate Routes Build routes with easy to add waypoints, drag waypoints, delete waypoints, and give waypoints custom names. Export and share your routes with other boaters. Activate a route to see bearing (magnetic or true) to waypoints, estimated time to waypoints, and ETA at destination among other metrics. ** Record Tracks Review and playback previously recorded tracks. ** Create and Share Markers Add notes and measure distances to markers. ** Basic Features Location (GPS & Compass). Caliper tool. Display settings for custom chart options. Vessel details for hazard avoidance and route planning. Satellite and road map chart overlays. ** POI We've integrated with marinas.com so we can show points interest directly on the chart for features like marinas, boat ramps, anchorage areas, inlets, locks, harbors and more. ** Weather View weather forecasts for up to five days in the future including marine related weather like wind, gusts, swells, and wave information. ** Live Track Sharing Create a live track share and send the link to friends. When imported, followers will see your current location and previous track directly on the Sea Drive app or website. * We love feedback! Sea Drive is built by boaters for boaters. This is just the start of our journey and we would like you all to be a part of it with us! Please provide any and all feedback!

Verdict
PRO CHARTS and SeaDrive both sit at 4.5 stars, but that hides the real split: 89% of SeaDrive's written reviews are positive against 27% of PRO CHARTS's. SeaDrive also leads on update cadence (fortnightly vs every 2 months). PRO CHARTS's advantage is ratings volume (8.5K vs 263) and chart position (#187 vs unranked). On price, rating, ads and in-app purchases there is nothing between them.
