StackPilot Poker Timer

Features
Read full description

Run poker night like a professional tournament director. StackPilot is a premium tournament clock built for the table — a gorgeous, room-readable timer designed iPad-first, with animated blind changes, break handling, and a refined look in felt green and gold. THE SEAT DRAW CEREMONY Stop scribbling names on napkins. StackPilot deals branded cards face-down onto a virtual felt table, then flips them one by one to reveal each player's seat — with haptics, chip drops, and the Ace claiming Seat 1 and the dealer button. It's the first big moment of the night, before the first hand is even dealt. A CLOCK EVERYONE CAN READ • Big, bold timer built for TV mirroring and across-the-room glances • Animated level changes with sound and voice announcements • Automatic breaks, with "play resumes at" times • Paused state that's unmistakable from the couch • Keeps the screen awake through the whole game FULL TOURNAMENT DIRECTOR TOOLS (PRO) • Player roster — entries, re-entries, add-ons, and eliminations • Optional results calculator — set final placements and work out the split however your group decides (1st / 2nd / 3rd and beyond) • Blind structure editor — Standard, Turbo, Deep Stack presets or fully custom levels, breaks, and antes • Seat draw ceremony with dealt cards and dealer button • Save your setup as a template and reuse it every game night • Remote control — pause the clock or eliminate players from your iPhone while the iPad stays on the table • Player database with lifetime stats, win rates, and a league leaderboard • Complete tournament history FREE FOREVER The tournament clock, blind structures, and setup basics are free — no account, no ads, no subscription. One $4.99 purchase unlocks everything else, forever, with Family Sharing. BUILT FOR YOUR GAME Whether it's a casual home game or your league's championship, StackPilot handles dead-button rules, house rotations, late entries, and the blind-movement debates that stall every home game (there's a built-in Poker Rules reference for that). StackPilot is a tournament timer and organizer for in-person games. It involves no wagering, no real money, and no simulated gambling of any kind. Shuffle up and deal.
