Memory-Map for Android

I use MM for sailing, in conjunction with other navigation tools. Never trust your boat & crew's safety to one method of determining your fix, but having said that, MM is a good nav program to have in your pocket.

I've used this app for many years now and it is my go to navigation aid. It is feature rich and does take some learning. Part of the learning is understanding what it is good at and what it is not so good at. It makes 180° errors too. U need a separate compass as a backup and sanity check. U can't rely on the 'navigate to' waypoint using the inbuilt compass and red/green arrow alone. You can't enter lat/long and zoom to that map point. Some of the route functions are a bit clunky. You can access tops maps for much of the planet and you can find your way. I've tried 3 or 4 others but this is the best and they keep improving it. Sometimes that's glitzy stuff that looks interesting but doesn't really impact but also things that make a difference. Highly recommended.

Great

This app is extremely simple you will need to spend some time to familiarize yourself on its operations but it couldn't be simpler. I've actually started use it as a go between when doin research for reef fishing or as a backup and have had to use it as such. Total life saver and worth every penny. Would like to have additional offshore maps and inshore maps with increased detailed overlays.

Terrible! Complete waste of time for boat navigation in us waters.
