Needs more work

So it's a bit annoying that the trip algorithm thinks that every time I cross a bridge I deserve congratulations on sailing, and it's twice as annoying that every time I try to delete that trip the app crashes. And for this I get the dubious award of 5 free log book entries...? Needs more work.

The app seems towork really well, but they were not upfront about pricing. I just don’t do reoccurring charges that automatically renew. I would rather pay up front, and even so 36$/year is too rich for my blood.

Customer service is very responsive if you have issues. App works great. It’s just don’t have the ability to make notes which is a big downside but they are fixing that
