Bankroll — your total betting budget. Think of it like a poker chip stack. You start with, say, $500, and every win adds to it, every loss takes from it. Bankroll Pro tracks this for you automatically.
Units — a unit is just your standard bet size. Most bettors use 1–2% of their bankroll as one unit. If your bankroll is $500 and one unit is $5, a "2-unit bet" means you're risking $10. Units let you compare your performance regardless of bankroll size.
Payout If Win — when you place a bet, this is the total dollar amount you'd receive if it wins (your stake + profit). For example, if you bet $10 and win $8 profit, enter $18.
Implied % — this is the probability your sportsbook is implying that your bet will hit, based on the odds. It tells you what the house thinks your chances are.
Pending bets — bets you've logged but haven't settled yet. Mark them as Win, Loss, or Push once the game ends.
