I bought the previous version. The one that worked without a monthly subscription. Navionics crippled it so it won't work anymore to force you in to a monthly subscription. This Company is untrustworthy and evil. Do not give them your money! I paid for a working app and you purposely broke it! Fix it or issue me a full refund! I know your standard response is to say you added features blah blah blah. I didn't ask for more features! I paid for the app I expect it to work like I paid for!
