Great Lakes HD Nautical Charts is currently exposed due to stability failures that prevent access to its core value proposition, which will accelerate churn if not addressed in the next release cycle. - 🔴 The latest update prevents the app from launching, which creates a critical churn risk for the user base. - 🔴 Restrictive zoom limits on charts hamper core navigation utility, leading to poor user experience despite the initial ease of map downloads. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 2.14/5 | | Total Reviews | 7 | | Sentiment | Frustrated (25/100) | | Confidence | Medium | | Pricing Model | Paid | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Great Lakes HD Nautical Charts** (this app) | 2.14/5 | Frustrated | Flytomap | | [CDOT Colorado Road Cameras](https://marlvel.ai/apps/cdot-colorado-road-cameras) | 5.0/5 | N/A | Brite Technologies | | [Find My Friends Phone - iMapp](https://marlvel.ai/apps/com-unwite-onthemap) | 4.2/5 | Mixed | Awared SLU | | [전국 시외버스 승차권 통합 예매(버스타고)](https://marlvel.ai/apps/com-ebcard-bustago) | 1.6/5 | N/A | EZL Corp. | | [손편지 - 내 손안에 편의점 지도](https://marlvel.ai/apps/app--288) | N/A/5 | N/A | GEONJU CHOI | | [탐나는맵](https://marlvel.ai/apps/com-tamnann-tamnannmapapp) | 3.3/5 | N/A | hyunseo Jung | ## Company Profile - **Developer:** Flytomap - **Website:** [https://www.flytomap.com](https://www.flytomap.com) - **Social:** [Facebook](https://www.facebook.com/flytomap) · [X/Twitter](https://twitter.com/flytomap) · [YouTube](https://www.youtube.com/watch) ## Data Sources & Links - **App Store ID:** 388093264 - **Dev Site:** [Official Website](https://www.flytomap.com) - **Sources:** Developer website content, About us / company information, App store metadata, User reviews. ## Related Intel Reports - [*CDOT Colorado Road Cameras*](https://marlvel.ai/apps/cdot-colorado-road-cameras) (Brite Technologies) · 5.0/5 Rating - [*Find My Friends Phone - iMapp*](https://marlvel.ai/apps/com-unwite-onthemap) (Awared SLU) · 4.2/5 Rating - [*전국 시외버스 승차권 통합 예매(버스타고)*](https://marlvel.ai/apps/com-ebcard-bustago) (EZL Corp.) · 1.6/5 Rating - [*손편지 - 내 손안에 편의점 지도*](https://marlvel.ai/apps/app--288) (GEONJU CHOI) · N/A Rating - [*탐나는맵*](https://marlvel.ai/apps/com-tamnann-tamnannmapapp) (hyunseo Jung) · 3.3/5 Rating - [*0-60 Drag Race Timer: GPS*](https://marlvel.ai/apps/0-60-drag-race-timer-gps) (Rui Pedro Correia) · N/A Rating | Excellent Sentiment - [*10-4 by WEX*](https://marlvel.ai/apps/com-wex-backoff) (WEX, Inc.) · 4.8/5 Rating - [*13:20:Sync*](https://marlvel.ai/apps/com-redhouseamsterdam-mayaapp) (The RedHouse Apps) · 4.9/5 Rating - [*23d GPS*](https://marlvel.ai/apps/23d-gps) (Shane Moore) · N/A Rating - [*360Finder - Real-time Locator*](https://marlvel.ai/apps/360finder-real-time-locator) (HONG KONG NOBLE LIMITED) · N/A Rating ## Frequently Asked Questions {#faq} ### Is Great Lakes HD Nautical Charts worth paying for if I only boat occasionally? The $14.99 one-time purchase is designed for users who want a low-cost alternative to dedicated marine plotters.

Yes, the app is designed for offline use. You can download full map coverage to your device, allowing you to navigate without cellular data or a mobile signal. ### What is the difference between this app and a dedicated marine GPS plotter?
