Great app to keep track of my boats from anywhere! When I'm away at sea it keeps me updated about who is around when i come back home or where they are going next so that makes our jobs easier as we can plan accordingly!! Nothing really but its easy enough if you know how stacktrack works then there isn't much else needed other than having an active account with them which not all people do (at least here). It would be great tho have more features added like using GPS tracking etc.. As far now though this has been very helpful especially during high season/ busy time periods such as summertime boating holidays ect.
