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.

Verdict
The clearest difference is rating: PRO CHARTS at 4.5 against Seapilot's 2.8. PRO CHARTS also leads on ratings volume (8.5K vs 16) and chart position (#175 vs unranked). Seapilot's advantage is review sentiment (38% vs 17%) and iOS requirement (9.3 vs 15.6). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. PRO CHARTS sells 4 in-app purchases, starting at $2.99 per month and Seapilot sells 18 in-app purchases, starting at $8.99 per year. Whichever you choose, the download price is not the number that matters.
PRO CHARTS holds the better App Store score, 4.5 against 2.8. That said, the two scores are not equally well evidenced: PRO CHARTS has 8.5K ratings behind it against 16, so its average is the more settled of the two. Written reviews complicate that: 17% of PRO CHARTS's written reviews are positive against 38% of Seapilot's, so the app with the better star average is not the one people write more warmly about.
PRO CHARTS ships an update every 2 months, Seapilot every 3 months. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
