About this app
What Wagerlog does
Wagerlog is a single private journal for every wager you place — across Kalshi, Polymarket, DraftKings, FanDuel, BetMGM, Caesars, a horse track, an office pool. You enter your stake, price, and side. When the event resolves, you log the outcome. Wagerlog computes EV, CLV (closing line value), and your true ROI by sportsbook + market type + sport. What's in v1: — Bet entry: book/platform, market (e.g. NBA moneyline, S&P close), side, stake USD, price (American odds or cents), expected resolution. — Resolution: outcome + final settled USD. — CLV input: when you have the closing line, enter it; Wagerlog computes whether you got CLV. — Roll-up: YTD ROI by book, by sport, by market type. Win rate, average odds, Kelly stake suggestion (for educational purposes only). — No broker integration. No social. Yours. Free.

Why it exists
The problem
PDF: 100K+ Polymarket accounts have lost $1K+. CNBC May 2026: most prediction-market traders lose money. The single best discipline change is keeping a written journal. Existing apps (Action Network, Bet Tracker Pro) are betting-feature heavy; Wagerlog is the calm journal.
What's different
How Wagerlog stands out
Wagerlog is platform-agnostic: it logs Kalshi event contracts the same way it logs DraftKings parlays. No bookmaker integration; no real-money handling; just the journal.
