I was answering a lot of questions for a new geocacher yesterday and he asked how to do a multi while caching with his phone, i.e. entering subsequent coordinates. I told him I have no idea since I don't use a phone to cache. I'm not sure what phone or program he is using, but he mentioned paying $9.99 for the app.
I asked someone I know that has used a phine and he didn't know of a way either. He suggested entering the coordinates into the map app and use that.
Thanks for any help.
