Even though my subscription is up to date, it continuously says I need to renew and the maps don't work. Very frustrating. I'm thinking of canceling my subscription. ### 2/5 — Not working *2023-08-05, version 5.41* Screen unresponsive ### 3/5 — Cut me short on annual time *2023-07-15, version 5.41* I purchased a years subscription. At 2 months left it stoped working. Scam. I will not recommend it again. If you pay for twelve months then you should get twelve months use. ### 4/5 — Cannot download marine charts *2023-04-09, version 5.41* Purchased the app, but the app will not permit any nautical charts to be downloaded. There is no table of definitions or a instruction set that I could find. The help/support function email that I appealed to yields no response. I was very disappointed. Kevin Leary ### 1/5 — Doesn't work *2023-02-11, version 5.41* App keep saying subscription expired and choose a plan. Same after subscribing and restoring purchases. Can't download charts. Use setting keep reseting chart to none. Save your money until it works. ### 1/5 — 👎 *2023-02-11, version 5.41* Terrible app…inconsistent charting, chart disappears randomly if it overlays at all. Tried it for two weeks then cancelled my subscription. Don’t waste your money. ### 1/5 — Doesn’t show depths *2023-01-10, version 5.40* I bought this app thinking it would be a way to navigate lakes but it’s no better than looking on google earth or OnX. There are no listed depths and topo lake maps are inconsistent at best. ### 1/5 — Miratrex navigation *2022-12-27, version 5.40* Worthless. Can’t log in, can’t set new username, can’t set new password. Worthless. Completely worthless. ### 3/5 — Quality issues *2022-12-08, version 5.40* I really like the app but there is a major issue with the subscription. Even though my subscription is up to date, it continuously says I need to renew and the maps don't work. Very frustrating. I'm thinking of canceling my subscription. ### 1/5 — This app is worthless. *2022-09-14, version 5.33* This app is worthless. It keeps telling me my subscription is expired when it’s not. I select the NOAA RNC or ENC chart and download it for the area I’m at, and it t displays for a second and then goes away and when you return to the chart page it’s has no chart selected. ### 1/5 — Worst App *2022-08-30, version 5.33* Stay away, you’re on your own with no way to talk to anyone. ### 3/5 — Serious Flaws Zero Support *2022-08-20, version 5.33* Application doesn’t have any customer support. Don’t be fooled by the App Support icon on Apple Store. They are claiming that you will be able to use both Android and IOS with a single license purchase this is NOT true. The user interface in android doesn’t recognize your purchase through Apple Store and there is NO a real company you can connect too… ALSO, The company domain (website) is blocked! Go check it if you want to see. ### 1/5 — Chart overlays *2022-08-13, version 5.33* Cannot get the chart overlays to display. ### 1/5 — Half hour to sign in???? This is not good. *2022-07-29, version 5.32* Bad 1/2 hour to use app ## Most critical reviews (10 lowest-rated) ### 1/5 — Not sure but this might be a scam *2025-07-08, version 5.70* Downloaded the app and have been trying to create an account for several days. Getting continuous Network Error messages and unable to create an account or use the app. But I was charged for it promptly. Very dissatisfied ### 1/5 — Network fail *2025-05-10, version 5.70* The app wouldn’t let me create an account. The app got stuck before I could even try to use it. Goodbye. ### 1/5 — Free is a lie. *2025-04-23, version 5.70* From your App page “Base App with limited features - Free” There is no free continual use as stated. ### 1/5 — Looks good…. *2024-09-08, version 5.70* This looks like the perfect app for my kayak fishing trips. Unfortunately, they won’t send me a confirmation email so that I could sign up. ### 1/5 — Glorified satellite map. *2024-07-01, version 5.70* Need to pay to even use the chart feature. Lame. ### 1/5 — This app blows *2024-02-21, version 5.70* Charts never seem to load ### 1/5 — Trial not working *2024-01-27, version 5.70* Charts are not showing ### 1/5 — False information *2023-10-17, version 5.41* Tells you two weeks free and that’s a lie you must have a plan with them to use that charts ### 1/5 — Garbage app *2023-10-08, version 5.41* No way you can rely on this app for navigation. The heading is not accurate. I am not able to download my charts in my area. I use it on Lake Tahoe and Monterey Bay and neither are available offline. I paid for the subscription and the app still reminds me to subscribe EVERY TIME I open the app, even if it’s already running in the background. Try a different nav app. That’s what I’m doing. ### 1/5 — Not happy *2023-05-09, version 5.41* Took my money and did not renew my subscription. ## Most praised reviews (10 highest-rated) ### 5/5 — Maine coast *2025-08-15, version 5.70* Great for navigating Middle/Maquoit bay for our camp ### 5/5 — In my pocket *2024-07-30, version 5.70* Having my charts and location instantly is very helpful when you need them. ### 5/5 — Just a great app! *2023-06-24, version 5.41* Been using this app for 8 yrs.
