Paid for the app and would like a refund as it is unreliable. ### 2/5 — Personal opinion *2026-06-03, version 4.6.0* This app needs a lot of work. When you compare to Satellite or navionics the shoreline accuracy is completely off missing lakes bays and islands. The whole feel is not very user friendly and feels “clunky” I hope things get better because I love the ever growing high resolution plotting but I don’t feel great about its accuracy. I would also like to see some of the “ spaghetti plate ” effect get cleaner up from user uploaded plotting. ### 3/5 — offline maps do not work *2026-06-02, version 4.6.0* I downloaded 2 sections of wrecks i planned to fish using the relief shading when I was connected to wifi and when I went out on the boat and got to my spots, my offline downloaded maps had zero of my pins to show for… other than that, i do find the app easily navigable and user friendly when connected to wifi or service… I just have to screenshot the coordinates to each spot i plan to hit before going out so I can type them in while on the water ### 3/5 — Great when it works *2026-05-18, version 4.6.0* I love using this app, but it crashes often, can’t ever update offline maps without deleting and re creating them, settings menu freezes, etc. ### 1/5 — Mal *2026-05-14, version 4.6.0* Ya van varias veces que al finalizar el track se me sale de la app y me borra el track, por lo que vale no me hace gracia ### 1/5 — Paid for subscription but subscription is not enable *2026-05-11, version 4.6.0* Seems like this app service is getting worse by the year….fix it or we just have to move to more reliable apps. ### 1/5 — Not work! *2026-03-25, version 4.6.0* Your app is not working on iPhones. It’s been down for a week! ### 1/5 — The App Just stopped working *2026-03-13, version 4.6.0* Previous I have really enjoyed the app as it’s clear and easy to use but suddenly it won’t work all I get is a white screen with the C-Maps logo I have deleted and reinstalled but still not joy ### 1/5 — GPS Tracking now not free *2026-03-03, version 4.6.0* The free gps tracking is now not free and subscription is $80. Seems expensive don’t need of the additional fancy functions e.g. shaded relief etc. ### 4/5 — Marina porto Caribe *2026-02-26, version 4.6.0* Exelent support & functionality through the years!! A must have tool. ### 3/5 — Pb chargement cartes hors ligne *2026-02-22* Impossible de charger les cartes hors ligne. Sur un iPhone et une tablette android ### 1/5 — Offline maps doesn’t work *2026-02-18* I have Downloaded offline maps before but could not veiw them offline. Now I can’t even download offline maps at all. When trying to contact the support the “contact support” feature also doesn’t work. I pay a yearly subscription and they are happy to receive my money but seems like the lights are on but nobody’s home in the C-map office. Maybe they have all gone sailing!? ## Most critical reviews (10 lowest-rated) ### 1/5 — Unstable location tracking and App crashed a lot *2026-08-25, version 4.6.1* After newest update, App become extremely unstable. Waste of my subscription ### 1/5 — Not usable *2026-08-22, version 4.6.1* Not usable. Crashes constantly. Boat location doesn’t show up. Always need to turn on map shading. ### 1/5 — Unusable *2026-08-18, version 4.6.1* The app is unstable and crashes unexpectedly, even though it is already updated to the latest version. The cursor showing my current position does not appear. The track recording randomly freezes, even though I have granted the app location access set to Always. I am extremely frustrated to have paid so much for an app that is ultimately completely unusable. ### 1/5 — Glitchy app *2026-08-14, version 4.6.1* App shuts off seconds after being opened. It does this repeatedly before it actually stabilizes. Then routing is far more finicky than the garmin app. ### 1/5 — Waste of money *2026-08-04, version 4.6.1* I have tried to use this app for a couple of seasons. At the start it worked fine and was quite useful. Last season, it would lose track of my location usually in important areas, like where I needed to know where I was to set anchor versus running aground or narrow channels with poor markings. This season , it won’t show my location on the map at all. This is a basic map function! I have deleted the app and re- downloaded it with the same issues. I want my money back and will use another app. ### 1/5 — Don’t bother *2026-08-04, version 4.6.1* I have been using this app for a while now and have overall found it great BUT after this last update it is unusable. I cannot even report the issue without it crashing so I am left paying for an app I can’t use and I can’t get help with. I can’t see my position. I can’t track. I can’t navigate away from the page or the app forgets I was using it. And it crashes constantly. It is not functional as a navigational aid. Thank goodness it’s not my primary aid or I would be screwed. ### 1/5 — Works then not! *2026-07-28, version 4.6.1* Works sometimes but crashes frequently when ypu switch apps. Today im pff san diego and i cant even get the app to start. I have 5g, I rebooted my phome and it starts and crashes before i het a map 5 Out of sox times. The last time it gets a map, Doesnt bring up a cours or roit and then crashes. Im done. Cancelling subscription ### 1/5 — Disappointed *2026-07-10, version 4.6.1* I did the free at first, then decided to do the paid version. Then when there was an update, it wiped out almost everything I had added . That is when I decided not to pay any longer. ### 1/5 — App freezes in settings *2026-07-06, version 4.6.1* App freezes every time I open setting using iphone 15 pro max. Will update review once developers fix. ### 1/5 — Glitchy at best *2026-07-05, version 4.6.1* This app used to be my go to for navigation on inland lakes and the Great Lakes. The app is buggy as can be. It continuously loses my gps location, navigation, etc. it kills any other music app that is playing while it is open. I had to completely delete it and reload it because it kept getting stuck on the settings page with just a spinning gear. I checked for updates to the app, hard rebooted my phone and still the same results each time. This is disappointing from an app that used to be so reliable. ## Most praised reviews (10 highest-rated) ### 5/5 — C-MAP *2026-07-24, version 4.6.1* Es una app bastante buena y completa uncluso mwjor q los ploters de algunos barcos ### 5/5 — Boater *2026-06-21, version 4.6.1* Looking for updates ### 5/5 — Super App! *2026-05-17* Preis Leistung stimmt ### 5/5 — Review *2026-05-16, version 4.6.0* Great graphics easy to use ### 5/5 — great lake *2026-04-01, version 4.6.0* we have used this on more then one crossing of lake michigan. and worked great. ### 5/5 — C-Maps review *2026-03-22, version 4.6.0* I just started to use it.
