Know where you actually stand. PLOT is a session and bankroll tracker for cash-game and tournament poker players who want an honest record of their results — what you played, how long you sat, and what it did to your bankroll. LOG A SESSION IN SECONDS Cash or tournament - plus jackpots, high-hand bonuses and room promos.. Stakes, buy-ins, top-ups, rebuys, add-ons and what you cashed out. Your recent setups sit on the home screen, so starting your usual game is one tap. RUN A LIVE SESSION Start the clock at the table. Add top-ups as you go, count your stack to see where you stand, and end it when you rack up. Closing the app doesn't stop the clock — the timer is derived from when you sat down, so it's still right hours later. SEE THE TREND A cumulative profit chart plus profit, $/hr, hours, win rate and session count — for this week, month, year, all time, or a range you pick. IN UNITS THAT ACTUALLY COMPARE bb/hr for cash games, so 8 bb/hr at $1/$2 counts as the same achievement as at $5/$10. ROI and ITM% for tournaments. FIND WHERE THE MONEY COMES FROM The same numbers broken down by stakes, game, venue and format. TRACK YOUR BANKROLL Sessions plus your own deposits, withdrawals and adjustments, so the number you see is the real one. KEEP IT TIDY Your own list of game types, venues and tags. Notes on any session. Search and filters over your whole history. TAKE YOUR DATA WITH YOU Export every session to CSV, or import one. PLOT reads its own exports and PokerBankrollTracker's, and skips sessions you already have. YOUR DATA STAYS YOURS Everything lives on your device and syncs through your own iCloud account. There's no PLOT account and no PLOT server. PLOT is free and shows one small banner ad. A single optional in-app purchase removes it for good, on every device signed in to your Apple Account. Requires iPhone running iOS 26 or later.
