Not much in the free realm, but for a few dollars you can get UpgradeU app for iPhone
for $20 one time purchase
and it's good for all the licenses. Also, Marine
Advancement program has a good review, it's what I have for studying my chief mate unlimited.. It's a USB that plugs into a Windows computer, doesn't need Internet
. That runs you just under $100. Might be less for the lower licenses, mine was that much.
are the Capt Murphy line of study books and there is another I can't think of..
Good luck either way!
