I suggest everyone here get this app. It's free for 30 days without any kind of sign up or anything then it's like $10 a year or something. Very easy to use and the most efficient way to follow your card IMO.
I have been using BetBud this year and have had pretty good luck with the app. I think it was free and then you could buy an upgrade that let you put in parlays and teasers etc. I have only had one issue where an NFL game didn't register for some reason. i just downloaded Bet Tracker to see which one I like better.
Might check it out. Was just counting my bets a minute ago, got 25 that'll be finishing in the next 72hrs.
