A Harford County man’s boating app is cruising to a new level of success after a little help from his daughter and a whole lot of TikTok users. It took just 12 seconds for millions of people to see Jeff Foulk’s hard work. The Havre de Grace business owner has been trying to get the word out about his boat navigation app for three years. So, his daughter spread the word to more than 20 million people on TikTok.
