A note from the maker
Why I started Terento
I’m Gediminas, a Garmin user who enjoys hiking in the mountains. Before a trip, I want my watch ready with maps for where I’m going. Getting those maps onto it often took more effort than it should.
I started Terento to make that easier for myself and other Mac users. I’m keeping it free and open source because I want this small solution to be useful to the community.
