## Most critical reviews (4 lowest-rated)

### 1/5 — Why

*2020-07-07*

For any Great Lakes  users it's useless.  No data whatever.

### 1/5 — No information provided

*2018-05-13*

This app provides zero marine information overlay.  Only provides a generic land map.  No marine information provided

### 3/5 — Useful but not the ants pants

*2024-11-24*

Pretty good for map and markers but no reliable depth details. OK therefore for sports and recreation use. More serious users would prefer C-map paid version.

### 4/5 — Needs more coverage

*2019-03-07*

The OpenSeaMap project appears to only cover some specific areas, but from what I can see where there is data provided it looks great. I look forward to US West coast coverage!!
