I like offline charts, routes, tracks, etc. However the app adds circles that clutter my screen. My useage was brief and I didnt explore settings. What was really annoying was the app stopped working, apparently when my trial period was over (?). I did a multi-day paddle and it wouldn't even skow my position on the chart. There was no notice or earning, just stopped working.

Very expensive app to maintain. You're forced to pay for the updates to the amount of $25.00 PER CHART each time..And if you switch to a new phone or other device, you must pay for the charts and downloads each time. This app is very expensive over time. On the plus side, the charts appear to be quite accurate. This developer needs to set up customer accounts so users can transfer charts between devices. Upgrades should not cost as much as the initial download! They also do not reply to email.

Every year at renewal time I have to contact support to get a new registration key and it never works. I have to go back and forth with them to get it to work. what a pain. When the app works most of the time it works well. Sometime the track will turn off during a trip and you would not know it happens. This app makes a good backup plan for boaters.
