## Description

PRO CHARTS - Marine Navigation is a powerful yet easy-to-use navigation tool designed for mariners. It provides offline NOAA charts, one-touch waypoint and route creation, and simple point-and-steer navigation to help you stay on course, even when you’re out of network. 

Key features include buddy tracking, float plans that can be shared with friends or family, a fully indexed POI database (weather, aids to navigation, obstructions, tides, currents, and more), and real-time position tracking. The extension supports offline chart caching, so you can view charts without internet access, making it ideal for remote or offshore voyages.

## Review summary

Users frequently report account creation/login failures, persistent subscription and billing problems, and charts that fail to load, disappear, or are unavailable offline. Support is often described as unavailable. A smaller set appreciates chart access when it works and long-term usage, but the dominant feedback is reliability and licensing friction.

### Pros

- Having charts and location instantly is helpful when you need them.
- Long-term users report value and there is feedback that tech support has been helpful.

### Cons

- Account signup/login problems (unable to create an account or sign in).
- Subscription and billing issues (expired/renewal problems, being prompted to subscribe, devices not syncing purchases).
- Charts failing to load, download, or display; offline maps not available in some areas.
- Poor or non-existent customer support and communication.
- Chart overlays not displaying and overall chart reliability issues.
